Dallas Love Field (IATA: DAL, ICAO: KDAL, FAA LID: DAL) is a city-owned public airport in the neighborhood of Love Field, 6 miles (9.7 km; 5.2 nmi) northwest of downtown Dallas, Texas. It was Dallas' main airport until 1974 when Dallas Fort Worth International Airport (DFW) opened. Love Field covers an area of 1,300 acres (530 ha) at an elevation of 487 feet (148 m) above mean sea level and has two runways.

Love Field is the birthplace, corporate headquarters, and a major operating base of Southwest Airlines; as of August 2021, Southwest has a 95% market share at the airport. Several full-service fixed-base operators (FBOs) provide general aviation services: fuel, maintenance, hangar rentals, and air charters. The City of Dallas Department of Aviation headquarters is on the airport grounds.

Dallas Love Field is named after Moss L. Love, who, while assigned to the U.S. Army 11th Cavalry, died in an airplane crash near San Diego, California, on September 4, 1913, becoming the tenth fatality in U.S. Army aviation history. His Wright Model C biplane crashed during practice for his Military Aviator Test. Love Field was named by the United States Army on October 19, 1917.

Dallas Love Field originated in 1917 when the Army announced it would establish a series of camps to train prospective pilots after the United States entered into World War I. The airfield was one of 32 new Air Service fields. It was constructed just southeast of Bachman Lake, and it covered over 700 acres and could accommodate up to 1,000 personnel. Dozens of wooden buildings served as headquarters, maintenance, and officers' quarters. Enlisted men had to bivouac in tents.

Love Field served as a base for flight training for the United States Army Air Service. In 1917, flight training occurred in two phases: primary and advanced. Primary training took eight weeks and consisted of pilots learning basic flight skills under dual and solo instruction. After completing their primary training at Love Field, flight cadets were transferred to another base for advanced training.

After officially opening on October 19, 1917, the first unit stationed at Love Field was the 136th Aero Squadron, transferred from Kelly Field, south of San Antonio, Texas. Only a few U.S. Army Air Service aircraft arrived with the 136th Aero Squadron, and most of the Curtiss JN-4 Jenny aircraft to be used for flight training were shipped in wooden crates by railcar. Training units assigned to Love Field during World War I were:

The 865th Aero Squadron (Repair) was formed at Love Field in March 1918 as a JN-4 aircraft repair and maintenance support unit. It was assigned to the Aviation Repair Depot, Dallas, Texas (at Love Field), in April 1918 and demobilized in March 1919.

With the sudden end of World War I in November 1918, the future operational status of Love Field was unknown. Many local officials speculated the U.S. government would keep the field open because of the outstanding combat record established by Love-trained pilots in Europe. Locals also pointed to the optimal weather conditions in the Dallas area for flight training. On November 11, 1918, cadets in flight training were allowed to complete their training; however, no new cadets were assigned to the base. The separate training squadrons were consolidated into a single Flying School detachment, as many of the personnel assigned were being demobilized.
