from Wikipedia

Phoenix Sky Harbor International Airport (IATA: PHX, ICAO: KPHX, FAA LID: PHX) is a civil-military public international airport 3 miles (2.6 nmi; 4.8 km) east of downtown Phoenix, in Maricopa County, Arizona, United States.[3] It is Arizona's largest and busiest airport; among the largest commercial airports in the United States, PHX was the 11th-busiest airport in the United States in terms of passenger boardings and 35th-busiest in the world in 2024.[5] The airport serves as a hub for American Airlines and a base for Frontier Airlines and Southwest Airlines.

Key Information

The airport is also home to the 161st Air Refueling Wing (161 ARW), an Air Mobility Command (AMC)–gained unit of the Arizona Air National Guard. The military enclave is known as Goldwater Air National Guard Base. One of two flying units in the Arizona ANG, the 161 ARW flies the KC-135R Stratotanker aircraft. In addition to its domestic role as a National Guard unit, answering to the Governor of Arizona, the 161 ARW also performs both a stateside and overseas role as a USAF organization, supporting air refueling and air mobility missions worldwide.[6]

Sky Harbor Airport's evocative name was conceived by J. Parker Van Zandt, the owner of Scenic Airways, who purchased 278 acres of farmland for Scenic's winter operations in November 1928. Sky Harbor was not only named but founded and built by Van Zandt in late 1928. He immediately commenced building a 100 x 120 foot airplane hangar and through early 1929 built one runway. This was the fourth airport built in Phoenix.[7] Scenic Airways, lacking funds after the infamous Stock Market Crash of 1929,[8][7] sold the airport to Acme Investment Company, which owned the airport until 1935, when the city of Phoenix purchased Sky Harbor airport from Acme for $100,000.[9]

Historical airline service

[edit]

On February 23, 1929, Maddux Air Lines began the airport's first scheduled passenger service with a route between San Francisco and El Paso stopping in Phoenix, Los Angeles, and several other cities; however the service was short-lived, ending by autumn 1929. Standard Air Lines had been serving Phoenix since late 1927 at a different airport and began landing at Sky Harbor on August 5, 1929. Standard operated a route between Los Angeles and El Paso stopping at Phoenix, Tucson, and Douglas, Arizona. Standard was acquired by American Airways in 1930 which later became American Airlines. American extended the route eastward to New York by way of Dallas, Nashville, and many other cities making for a southern transcontinental route across the United States.[10]

TWA began service to San Francisco in 1938 and added Phoenix onto its transcontinental network by 1944 with flights to Los Angeles and eastward to New York stopping at Albuquerque, Kansas City, and many more cities. Arizona Airways began intrastate service within Arizona in 1946 and merged into Frontier Airlines in 1950 which added new routes to Denver, Albuquerque, and El Paso. Bonanza Airlines began service by 1951 with a route to Las Vegas and Reno making several stops at smaller communities. New routes to Salt Lake City and Southern California were added in the 1960s along with nonstop flights to Las Vegas and Reno aboard Douglas DC-9 jets by 1965. Bonanza merged with two other carriers to become Air West in 1968 and was changed to Hughes Airwest in 1970 adding several new routes, including service to Mexico, creating a hub at Phoenix. Hughes Airwest was then merged into Republic Airlines in 1980 which continued the Phoenix hub operation until the mid-1980s. Western Airlines came to Sky Harbor in 1957 with flights to Denver, Los Angeles and San Diego, Continental Airlines came in 1961 to El Paso, Los Angeles, and Tucson, and Delta Air Lines began flights to Dallas by 1969.[9]

Bonanza Air Lines moved its headquarters from Las Vegas to Phoenix in 1966. Bonanza merged with two other airlines to form Air West, which became Hughes Airwest after Howard Hughes bought it in 1970.[11]

After the Airline Deregulation Act was signed in 1978, many new airlines began service to Sky Harbor. In 1978, former Hughes Airwest executive Ed Beauvais formed a plan for a new airline based in Phoenix. He founded America West Airlines in 1981, which began service from Phoenix in 1983 and doubled in size during its first year.[11] Allegheny Airlines and Eastern Airlines soon began service in 1979 followed by United Airlines in 1980. Allegheny changed its name to USAir shortly after beginning service in 1979. Southwest Airlines arrived at Phoenix in January 1982 with 13 daily flights to 12 cities; by 1986 it had 64 daily flights from Phoenix and had a crew base there. Southwest opened a maintenance facility at PHX in 1992, which was its largest.[12]

America West filed for Chapter 11 bankruptcy protection in 1991 and sold its larger aircraft and Japanese route authority, but continued growing its domestic operations from Terminal 4 in cooperation with Continental Airlines. Although AWA enjoyed further growth at Phoenix during the 1990s the aftermath of the September 11 attacks strained its financial position. AWA ended its relationship with Continental and merged with US Airways in 2005. US Airways moved its headquarters to the AWA campus in Tempe and retained many AWA managers to run the merged company. US Airways was then merged into American Airlines in 2015 which continues to build upon the largest hub operation at Phoenix Sky Harbor.[11]

Sky Harbor landed its first transatlantic flights in 1996 when British Airways inaugurated nonstop service to London. The flight was first operated with a Douglas DC-10 aircraft but soon upgraded to a Boeing 747-400.[13]

In May 2025, Starlux Airlines announced they would launch service in 2026 to Taipei, Taiwan, on an Airbus A350 aircraft, marking the first time an airline announced non stop service to Asia from the airport.[14] On 25 July 2025 China Airlines announced that it will start nonstop flights to Taipei, starting on December of that year.[15][16]

Facilities expansions and growth

[edit]

After World War II, the airport began work on a new passenger terminal, as well as a new parallel runway and a diagonal runway.[17] On the February 1953 C&GS diagram runways 8L and 8R are each 6,000 feet (1,800 m) long and runway 3 is 5,500 feet (1,700 m). The $835,000 Terminal 1 (originally called the West Wing), which also had the first control tower, opened in October 1952.[17]

The airport's master plan was redesigned in 1959 to eliminate the cross runway to make room for new terminals.[17] American and TWA began jet service to Phoenix in 1960 and 1961 respectively, and Terminal 2 (originally called the East Wing) opened in 1962.[18] Terminal 2 was designed by the Phoenix architectural firms of Weaver & Drover and Lescher & Mahoney and opened in 1962.[19] Terminal 2 also featured a 16-foot (4.9 m) high and 75-foot (23 m) wide mural composed of 52 different materials, including mosaic glass, gemstones, shells, and vintage toys.

The Phoenix, designed by the late French-American artist and full-time resident of Phoenix Paul Coze, was commissioned in 1960 as Phoenix's first work of public art and was installed in 1962 in the main lobby area of the terminal. The Phoenix was relocated to the Rental Car Center in 2021 following the decommissioning and demolition of Terminal 2.[20] In November 2006, a Military and Veterans Hospitality Room, sponsored by the Phoenix Military and Veterans Commission, was opened in Terminal 2. It has since relocated to Terminal 4 as the new USO club. This terminal underwent two renovation projects. The first was completed in 1988.[21] The second project, which cost $24 million and was designed by DWL Architects + Planners, Inc., was completed in 2007.[19]

Construction on Terminal 3 began in January 1977. Designed by DWL Architects + Planners, Inc., Terminal 3 opened in October 1979, and the "East" and "West" names were dropped since there were no longer only two terminals.[17]

A USAir Boeing 737-300 at Phoenix Sky Harbor International Airport on February 28, 1986. This aircraft, N360AU, would later be re-registered as N388US, and would go on to crash at Los Angeles in 1991 as Flight 1493

In October 1989, ground was broken for Terminal 4, the largest terminal.[22] It opened on November 2, 1990,[23] with four concourses: N2 and N3 on the north side and S3 and S4 on the south side. In 1994 the N4 International Concourse was opened, adding 10 gates and a sterile walkway to the S4 concourse. In 1997 construction began on the 14-gate N1 concourse for America West Airlines. It was completed in June 1998 at a cost of $50 million,[24] completing the expansion of the north side of the terminal. On the south side of the terminal, construction began in 2002 on the eight-gate S2 concourse for Southwest Airlines. This project was completed in 2004 and has a different architectural design from the other six concourses. The eighth and final concourse for Terminal 4, S1 (South 1), with gates D11–D18, began construction in May 2019. Terminal 4 is named after former Arizona Senator and 1964 Presidential candidate Barry M. Goldwater. After Goldwater's death in 1998, the then-mayor of Phoenix, Skip Rimsza, proposed renaming the airport in Goldwater's memory but was deluged with public support for the familiar "Sky Harbor" name.[25] Terminal 4, designed by DWL Architects + Planners, Inc., is the largest and busiest of the two terminals with 86 (now 92) gates, divided into eight satellite concourses connected behind security.[19]

In 2007, the Transportation Security Administration introduced the first of its backscatter X-ray machines at PHX.[26]

Recent developments

[edit]

In February 2020, Terminal 2 accepted its final flight and was then decommissioned. Demolition occurred in early 2021 with the terminal being replaced by concrete stands for aircraft, accessible by bus from other terminals.[27] Airlines previously using Terminal 2 were relocated to Terminal 3, which had completed renovations in January 2020.[28]

In January 2021, Terminal 3 was renamed in honor of Senator John McCain by the Phoenix City Council.[29]

In February 2024, the airport announced plans for infrastructure upgrades at its central utility plant in Terminal 4, which will improve air conditioning at the airport. The $36 million project was funded by a FAA Airport Terminal Program grant included in the federal Infrastructure Investment and Jobs Act that was signed into law by President Joe Biden.[30]

On April 29, 2024, Phoenix Mayor Kate Gallego announced that a new terminal would be constructed on the west end of the property near the former location of Terminal 2. She said that in 2023 the airport welcomed more than 48 million passengers and with continued growth expected the new terminal was needed to accommodate growing demand and handle the increased number of travelers. The terminal would feature a new customs facility and would be designed to have net-zero greenhouse gas emissions, making it an environmentally friendly structure.[31]

In 2024, the airport surpassed 50 million passengers in a single calendar year, an all-time record for the facility.[32]

Christmas Day shooting and stabbing

[edit]

On December 25, 2024, an apparent family dispute among a group of five at a restaurant in Terminal 4 escalated into a shooting and stabbing, leaving three with gunshot wounds and another with a stab wound. A man and a juvenile female were detained as a result of the incident. After the domestic incident, a man allegedly responding to false reports of an active shooter at the airport arrived at the airport shirtless and armed. The man had an altercation with police before he was also arrested.[33][34]

Terminals

[edit]

The airport has 119 active aircraft gates in two Terminals (3 and 4).[35] The airport administration states that the designations Terminal 1 and Terminal 2 have been "retired" and that it did not wish to renumber the other terminals since passengers were already familiar with the numbers in place.[36] Terminals 3 and 4 continued to retain their numbers after the closing of Terminal 2.[37] Bus gates are planned to be operated on the Terminal 2 site.[38][36][39][40] Terminal 3 is used by most domestic or precleared arrivals including Frontier Airlines.[41] Alaska Airlines also uses Terminal 3 for both its arrivals and departures.[6] International carriers, American and Southwest operate in Terminal 4.[42]

  • Terminal 3 contains 27 gates.[35]
  • Terminal 4 contains 92 gates.[35]

Runways

[edit]

PHX covers 3,400 acres (14 km2) at an elevation of 1,135 ft (346 m). The airport has three parallel concrete/grooved runways:[3][43]

  • Runway 8/26 measuring 11,489 ft × 150 ft (3,502 m × 46 m)
  • Runway 7L/25R measuring 10,300 ft × 150 ft (3,139 m × 46 m)
  • Runway 7R/25L measuring 7,800 ft × 150 ft (2,377 m × 46 m)

All three runways can accommodate aircraft with a maximum takeoff weight of 900,000 lb (410,000 kg) or greater.[3]

Sky Harbor's private airplane area is also one of eight service centers for the Medevac airline Air Evac.[44]

ATC tower

[edit]

The airport's 326-foot-tall (99 m) air traffic control tower began operations on January 14, 2007. It stands just east of the Terminal 3 parking garage and also houses the Phoenix TRACON. This is Sky Harbor's third control tower and is among the tallest control towers in North America.[45][46]

Museum

[edit]

The Phoenix Airport Museum is a museum displaying artwork and local aviation memorabilia located inside the terminal.[47]

Ongoing projects, including terminal modernizations and capacity enhancements, address persistent growth pressures amid projections for continued exceeding 60 million passengers by the early 2030s.

History

Early Development and Establishment

Phoenix Sky Harbor Airport was founded as a private airfield in late 1928 by J. Parker Van Zandt, owner of Scenic Airways, who purchased 278 acres of cotton fields east of 24th Street and south of the Southern Pacific railroad tracks in Phoenix. Van Zandt named the site Sky Harbor, envisioning it as a hub for aerial operations, and oversaw the construction of a dirt landing strip, an office building, and a , with initial operations commencing by early 1929. The facility supported early activities, including the start of scheduled passenger service that year via Scenic Airways, reflecting the era's growing interest in amid Phoenix's population expansion from and . The 1929 stock market crash strained private ownership, leading Van Zandt to sell Sky Harbor to Acme Investments Company in the early 1930s. established service at the airport in 1930, utilizing it for regional routes. In 1934, Acme leased the facility to Maricopa County for management, but the county relinquished the lease the following year amid financial pressures and operational challenges, leaving the site's future uncertain. To avert the discontinuation of ' operations—which had warned of withdrawal without stable municipal oversight—the City of Phoenix acquired Sky Harbor from Acme on July 16, 1935, for $100,000, encompassing approximately 285 acres then nicknamed "The Farm" for its isolated, rural character. The transaction involved $35,300 paid in cash and a $64,700 , marking the airport's transition to public ownership and its formal establishment as a city-managed asset. At this stage, infrastructure remained rudimentary, consisting primarily of the original runway and basic structures, with no dedicated passenger terminals until later decades; the purchase prioritized continuity of commercial air service over immediate expansion, aligning with Phoenix's economic reliance on connectivity to distant markets.

World War II Era and Initial Commercial Operations

During the era, Phoenix Sky Harbor Airport played a key role in activities. In 1940, the established its regional headquarters at the facility, which was expanded to 320 acres and equipped with its first control tower to support operations, including aircraft refueling. By April 1943, the airport hosted flying training programs for personnel and aviation students from Allied nations, leveraging Arizona's favorable weather for pilot instruction. That same year, the Navy Air Transport Service incorporated Sky Harbor as a scheduled stop on its transcontinental cargo and personnel routes, enhancing its logistical importance. Commercial operations persisted alongside military use, with airlines such as , , and Southwest Airways maintaining service using a total of 35 . Infrastructure improvements included the paving of the first in 1945 and the addition of a second story to the control tower in 1944 for better oversight. A 64-seat Sky Chefs restaurant opened in 1943 to accommodate travelers and service members, reflecting the dual civilian-military demands. Following the war's end in 1945, Sky Harbor rapidly shifted toward expanded . By , it was served by three major airlines and ranked as the busiest airport in the United States, with the site growing to 400 acres to handle surging demand. Passenger traffic climbed to 240,786 in 1950 amid Phoenix's to approximately 105,000, prompting further developments like the completion of Terminal 1 and a new control tower in 1952 at a cost of $835,000. These enhancements solidified the airport's role as a burgeoning commercial hub, with traffic reaching 296,066 passengers by the end of 1952. The also initiated operations there in 1949, marking a continued presence amid expansion.

Post-War Expansion and Airline Hub Growth

Following , Phoenix Sky Harbor underwent significant infrastructure upgrades to accommodate surging civilian air traffic, including construction of a new passenger terminal and additional s. Terminal 1 opened in September 1952 at a cost of $835,000, constructed by Mardian Construction Co., replacing outdated facilities and featuring a modern control tower. Concurrently, the airfield expanded with a new parallel (08/26) and a diagonal (03/21) to handle increased operations and mitigate congestion from military-era limitations. Passenger volumes reflected this growth, rising from 240,786 in 1950 to 296,066 in 1952, driven by Phoenix's booming population and tourism appeal. By 1962, Terminal 2 opened in April after a $2.7 million investment, encompassing 330,000 square feet, 19 gates, and a 1,000-car parking garage, coinciding with the airport surpassing one million annual passengers for the first time. These developments supported steady traffic increases through the and , with Terminal 3's opening in 1979 boosting capacity further as volumes reached 7 million passengers annually. The airport's evolution into a major airline hub accelerated in the 1980s with the launch of , founded in 1981 and commencing operations on August 1, 1983, from Phoenix as its primary base. Headquartered in nearby Tempe, the carrier initially deployed three leased 737-200s for short-haul western U.S. routes, capitalizing on to offer low-fare service and rapidly expand connectivity from Sky Harbor. This focus prompted dedicated infrastructure like the N-1 concourse in November 1986, adding 12 gates to accommodate America West's fleet growth and hub operations, which by the late 1980s handled a substantial share of the airport's traffic. 's strategy transformed Phoenix into a key southwest connecting point, fostering long-term hub dominance later inherited by successors and .

Major Infrastructure Modernizations

In 1976, construction began on Terminal 3, which opened in 1979 after costing $35 million for the terminal structure and an additional $13 million for its accompanying parking garage; the facility spanned 880,000 square feet with 23 gates. A new control tower, standing 185 feet tall, opened in 1977 to handle increasing air traffic demands. Terminal 4, the airport's largest capital improvement to date at $248 million, broke ground in October 1989 and commenced operations in November 1990; it initially featured 3.9 million square feet and 44 gates, later expanded to 94. In 2000, the north underwent extension, and a third parallel opened alongside a new south-side cargo facility to accommodate growing jet operations and freight volume. The existing 326-foot air traffic control tower, positioned east of the Terminal 3 parking garage and incorporating the Phoenix Terminal Radar Approach Control, entered service on January 14, 2007, replacing prior structures to enhance visibility and capacity for over 1,300 daily flights. Terminal 4 received further upgrades, including a seventh (D Concourse) in 2005 adding 180,000 square feet and gates D1-D8, followed by checkpoint expansions in 2009. The PHX Sky Train automated people mover launched in stages: Stage 1 in 2013 linking Terminals 3 and 4, Stage 1A in 2014 connecting all terminals, and Stage 2 in 2022 extending 2.5 miles to the Rental Car Center with two new stations for 24/7 service. Terminal 3's $590 million modernization, initiated in 2016, culminated in 2020 with renovated security checkpoints, ticketing areas, and concourses, including the North Concourse opening that year; Terminal 2 closed concurrently in February 2020 after remodeling in 2007. An eighth concourse at Terminal 4, adding eight gates and 275,000 square feet, opened in June 2022.

Key stations include the 44th Street/Washington hub for integration, East Economy Parking for long-term vehicle access, Terminal 4 (primary international and major domestic hub), Terminal 3 (domestic focus), and the Rental Car Center for off-site vehicle services. Travel times range from 2 to 6 minutes between stops, providing air-conditioned, elevated views of the airport grounds and reducing reliance on roadways. By diverting approximately 20,000 vehicles daily from airport roads, the Sky Train has lowered by nearly 6,000 tons annually and supported ridership growth to connect over 14 million travelers yearly to the facility. No other dedicated intra-airport rail or systems operate at Phoenix Sky Harbor, with passenger navigation within individual terminals relying on extensive pedestrian walkways, escalators, and rather than automated intra-terminal movers. The Sky Train's implementation has been credited with improving overall efficiency, particularly amid passenger volume exceeding 52 million annually pre-pandemic, by minimizing bus emissions and wait times compared to prior shuttle dependencies.

Road Access and Highway Connections

Phoenix Sky Harbor International Airport is situated adjacent to (I-10), the Papago Freeway, which forms its northern boundary and serves as the primary east-west corridor for accessing the facility from central and western . Travelers from or points west typically exit I-10 eastbound at Exit 153B for 24th Street or continue to Exit 154 for SR 143 northbound, merging onto Sky Harbor Boulevard to reach the terminals. From the east, westbound I-10 provides direct ramps to SR 143 and Sky Harbor Circle, facilitating entry via the airport's internal roadway system. Arizona State Route 143 (SR 143), designated as the Expressway, runs parallel to the airport's eastern perimeter, offering a crucial north-south link between I-10 to the south and Loop 202 (Red Mountain Freeway) to the north. This four-lane freeway connects directly to the airport via exits to Washington Street and Sky Harbor Boulevard, enabling efficient access for East Valley commuters from areas like Mesa and Tempe. SR 143's interchanges with I-10 and Loop 202 handle significant volumes of airport-bound traffic, though periodic closures for maintenance, such as those during the Broadway Curve Improvement Project, require detours via Loop 202 or alternative I-10 ramps. Loop 202 provides circumferential access encircling eastern Phoenix, with westbound segments linking to SR 143 southbound (Exit 5) for direct entry to the airport's East Economy Parking and Terminal 4 areas. This route is particularly vital for avoiding downtown congestion, integrating with the broader regional freeway network including Loop 101 to the north. Local arterials like Buckeye Road and Drive supplement highway access for nearby neighborhoods, feeding into Sky Harbor Boulevard, which distributes traffic to parking garages and curbside drop-offs at Terminals 3 and 4. Ongoing infrastructure enhancements, including taxiway bridges over access roads, aim to minimize disruptions from the estimated 40 million annual vehicles in the vicinity.

Public Transit, Parking, and Rental Services

Public transit access to Phoenix Sky Harbor International Airport is facilitated primarily through the Valley Metro light rail system, with direct connectivity at the 44th Street/Washington station. Passengers disembark the light rail and transfer to the complimentary PHX Sky Train, an automated people mover that links the station to Terminal 4, the Rental Car Center, and the East Economy Parking area, operating 24 hours daily. This integration allows travel to downtown Phoenix, Tempe, Mesa, and other Valley Metro destinations, with light rail service running approximately from 4:30 a.m. to 1:00 a.m. on weekdays and adjusted hours on weekends; a one-way adult fare is $2, valid for up to 2.5 hours of travel. Valley Metro bus routes supplement rail service, providing additional options to regional points, though remains the most direct public option for airport-bound travelers due to its proximity and frequency. Parking facilities at the airport encompass terminal-adjacent garages offering covered spaces with walkways to Terminals 3 and 4, as well as remote economy lots with dedicated shuttle service. The East Economy Parking lot charges $12 per day as of October 2025, with shuttles delivering passengers to the station at the Rental Car Center for onward terminal access. Reservations are recommended during peak periods to secure availability, and the airport maintains a 24-hour parking assistance at 602-273-4545. Rental car services are consolidated at the dedicated Rental Car Center, situated south of the terminals and reachable via the 24-hour from Terminal 4 or connections. This facility houses counters and vehicle lots for participating providers, streamlining pickup and return processes for arriving and departing passengers; economy parking shuttles also serve the center directly.

Incidents, Accidents, and Controversies

Aviation Accidents and Safety Events

On October 12, 2005, Flight 2676, a 737-7H4 (N755SA), collided with the tail section of a stationary 737-3H4 (N624SW) while taxiing to its gate at Phoenix Sky Harbor International Airport (PHX); the incident caused minor structural damage to both aircraft but resulted in no injuries to the 134 occupants aboard the moving aircraft. The (NTSB) attributed the event to the pilots' failure to maintain visual contact with the parked aircraft during low-visibility ground operations. A occurred on March 19, 2010, when the crew of a 35A (N126QS) taxied onto an active runway without clearance while Flight 568, a 737-300, was on short for ; issued a order to the airliner, averting a collision with separation maintained at approximately 1,000 feet. The NTSB determined the as the Learjet pilots' inadequate and failure to follow taxi instructions, compounded by the lack of a stop bar system on the intersecting . On August 28, 2002, Flight 2441, an A320-231 (N635AW), experienced an asymmetrical thrust reverser deployment during landing rollout on Runway 26, causing the aircraft to veer off the runway and collapse its nose ; the 154 passengers and 5 crew members evacuated without injury, though the aircraft sustained substantial damage. Investigation revealed a in the thrust reverser system due to improper maintenance and design flaws in the locking mechanism. PHX has experienced multiple near-midair collisions in recent years, with nine pilot-reported events between 2015 and 2024 involving aircraft arriving or departing the airport, often attributed to high traffic density and converging flight paths in the . A prominent case on January 11, 2025, saw Flight 3627 and Flight 1070 separate by only 440 meters horizontally and 61 meters vertically during simultaneous approaches to parallel runways, triggering a alert and prompting an FAA investigation into clearances. No fatal accidents have occurred on PHX runways or taxiways in the database of the Safety Network, reflecting effective safety protocols despite the airport's status as a high-volume hub handling over 40 million passengers annually. Incidents have primarily involved excursions, ground collisions, and violations, with NTSB recommendations focusing on enhanced pilot training, ground improvements, and procedural mitigations to address causal factors like and environmental conditions.

Security Incidents and Response Measures

An investigation documented 21 perimeter security breaches at Phoenix Sky Harbor International Airport between 2004 and early 2016, involving intruders who hopped, crawled under, or drove through fencing to access runways or airfields. These incidents included a 2005 case where a man fleeing police in a stolen crashed through a , prompting heightened scrutiny of access controls. None of the breaches were linked to known terrorist plots, though they exposed vulnerabilities in physical barriers despite post-9/11 investments in fencing and surveillance. In November 2012, Koko Nicole Anderson rammed her vehicle through a partially raised security gate at the airport, driving onto an active runway with her 2-year-old son inside before police stopped her. Anderson, who faced charges including child endangerment, entered a no-contest plea in 2015 and received probation, parenting classes, and mental health evaluation as part of the resolution. Similar unauthorized vehicle intrusions have occurred periodically, such as in 2017 when another driver struck a parked vehicle before breaching a gate, highlighting recurring challenges with gate reinforcement and rapid response. On December 25, 2024, a dispute at a Terminal 4 restaurant escalated into violence, resulting in three people being shot and one stabbed, with one victim in critical condition; the incident prompted a temporary order but did not involve perimeter or security compromise. Phoenix police investigated it as a domestic altercation, recommending charges against six individuals, including juveniles, for and weapons violations. In response to early breaches, the airport invested $10 million after the 2005 incident to upgrade perimeter , access , and detection systems, aiming to deter vehicle and pedestrian intrusions. The Secure Our Airport Responsibly (SOAR) program, launched to engage the public in vigilance, encourages reporting of suspicious activities to and personnel, supplementing federal TSA screenings with community-based threat identification. Despite these measures, perimeter incidents have continued at a rate of about one every few months historically, underscoring limitations in static barriers against determined or opportunistic trespassers. In March 2023, the City of Phoenix filed a against the City of Tempe, alleging breach of a 1994 intergovernmental agreement that restricted incompatible land uses, such as residential development, within designated high-noise contours east of Phoenix Sky Harbor International Airport. The dispute centered on Tempe's proposed Tempe , which included multifamily housing and an arena for the NHL team, potentially exposing future residents to aircraft noise exceeding 65 decibels and inviting subsequent nuisance lawsuits against the airport operator. Tempe countersued, claiming Phoenix's opposition violated prior allowances for similar developments and sought to block economic projects without evidence of imminent harm. The cities reached a settlement on December 6, 2024, amending the agreement to permit limited non-residential development while restricting multifamily housing to leasehold-only tenancies, prohibiting sales to individuals, and requiring noise disclosures and insulation for any approved structures. This resolution ended over three decades of contention, including prior disputes over aircraft impacts, and was influenced by the failed 2023 voter on the Coyotes' project, which heightened political tensions between the municipalities. Phoenix officials emphasized the accord's role in safeguarding airport operations from future litigation risks posed by noise-sensitive land uses, while Tempe viewed it as enabling controlled without conceding core . Phoenix has pursued multiple legal challenges against the (FAA) regarding flight procedure changes at Sky Harbor that altered noise distributions over urban areas. In June 2015, the city filed a petition under the contesting new Performance-Based Navigation (PBN) routes implemented in 2014–2015, which concentrated arrivals and departures over previously underflown neighborhoods in , leading to heightened noise complaints without adequate environmental review under the (NEPA). The suit, City of Phoenix v. Huerta, argued the FAA failed to assess cumulative impacts or alternatives, though federal courts largely deferred to the agency's technical expertise and dismissed key claims on procedural grounds. Adjacent jurisdictions have echoed these concerns; in 2020, the City of Scottsdale sued the FAA over similar PBN procedures, alleging insufficient evaluation of noise, air quality, and historic resource effects on nearby communities, but the D.C. upheld the FAA's environmental assessments in June 2022, citing compliance with statutory requirements for aviation efficiency. These cases highlight ongoing federal-local tensions, where FAA prioritizes national airspace modernization and fuel savings—PBN routes reduced flight times by up to 10 minutes—over localized noise mitigation, prompting Phoenix to invest in voluntary programs like over 10,000 nearby homes since 1981. No resolutions have mandated route reversals, but they have spurred enhanced FAA consultation with operators on community impacts. In August 2025, construction resumed on an on-airport facility for aviation employees following a settlement of a by opponents who contended the project lacked proper public input and environmental scrutiny; the dispute delayed groundbreaking but affirmed the city's authority under laws. Separately, the upheld Sky Harbor's rideshare fees—$4 for pickups and $2.80 via the —in April 2020, rejecting challenges that they unfairly burdened platforms like without legislative basis, thereby validating revenue mechanisms funding terminal improvements. These rulings underscore the airport's legal defenses against operational constraints, balancing economic viability with stakeholder objections.

Passenger Feedback and Criticisms

In the 2025 Airport Satisfaction Study, Phoenix Sky Harbor International Airport ranked third among mega airports (those handling over 33 million passengers annually), earning a score of 634 out of 1,000, reflecting improvements in , beverage, retail options, and ease of compared to prior years. This positioning highlights generally positive feedback on operational aspects, with the airport maintaining a top-three spot for the second consecutive year. Despite these aggregate survey results, individual passenger reviews often cite navigational challenges, particularly in Terminal 3, described as confusing and disorganized with inadequate signage leading to missed connections or frustration during transfers. Baggage handling draws recurring complaints, including delays at claim areas and misrouted luggage, as reported in multiple user accounts from 2018 to 2025. Security screening experiences vary, with criticisms of inconsistent TSA enforcement of rules—such as the 3-1-1 liquids policy—and occasional disrespectful interactions, though standard wait times remain manageable outside peak disruptions. Specific incidents amplify these issues; for instance, air conditioning maintenance in Terminal 4 on July 9, 2025, caused extended security queues exceeding typical durations, exacerbating summer heat discomfort for travelers. Baggage check lines have also faced scrutiny, with reports of waits up to two hours during high-volume periods like pre-holiday rushes in 2025, attributed to staffing and volume surges at low-cost carriers' counters. Parking feedback is mixed, praising frequent shuttles but noting high costs and occasional capacity strains during peak travel. Online review aggregates, such as Yelp's 3.3/5 rating from over 3,400 submissions, underscore these pain points amid otherwise helpful staff interactions.
