GoJet Airlines LLC is a regional airline headquartered in Bridgeton, Missouri, United States. Wholly owned by Trans States Holdings, it has 1,670 employees. It operates commuter feeder services under the United Express brand of United Airlines. United Express flights are currently operated out of United's hubs at Chicago–O'Hare, Newark and Washington-Dulles. GoJet's Delta Connection branded flights came to an end on March 31, 2020. Most of the flying at the end of the agreement was out of Detroit and Minneapolis–St. Paul as well as Raleigh–Durham International Airport. GoJet Airlines' system operations center (SOC), training center and corporate offices are co-located in the former Trans World Airlines and Ozark Airlines training center in Bridgeton, Missouri. The airline uses the former McDonnell Douglas factory hangar at Saint Louis Lambert International Airport as its primary maintenance facility, with maintenance staff available at all of the airline's destinations. Its call sign, "Lindbergh", is named for aviation pioneer Charles Lindbergh, who flew the Spirit of St. Louis solo across the Atlantic Ocean in 1927; the first person to do so.

The airline was established in late 2004 by Trans States Holdings. The airline would fly United Express-branded flights out of United Airlines' Chicago O’Hare hub to replace departing United Express carrier Atlantic Coast Airlines. GoJet took delivery of its first Bombardier CRJ700 in June, 2005.

The airline received its initial Air Carrier Operating Certificate in September 2005 and began scheduled passenger services on October 4, 2005, with a United Express flight from Cincinnati, Ohio to Chicago, Illinois. By the end of 2009, GoJet took delivery of its 25th CRJ700 aircraft.

In October, 2011, Delta Air Lines announced that it was planning a January, 2012 launch of new GoJet CRJ700 service as a Delta Connection regional carrier. Delta would initially transfer 15 of the CRJ700 aircraft previously assigned to its Comair division to GoJet, as well as 12 owned or leased CRJ700s contracted to SkyWest Airlines, to begin the service. On January 22, 2012, GoJet began service as a Delta Connection carrier with its inaugural flight from St. Louis, Missouri to Detroit, Michigan.^{[non-primary source needed]} In late 2013, GoJet agreed to increase its flying agreement for Delta by leasing several CRJ900 aircraft for its Delta Connection service through 2023. GoJet began this CRJ900 service in late 2014.

In August, 2019, Delta announced that it would be terminating operating agreements with two of its Delta Connection-branded carriers: GoJet Airlines and Compass Airlines. The CRJ700 aircraft operated by GoJet for Delta Air Lines will be transferred to Endeavor Air or sold to other operators. The CRJ900 aircraft that were leased by GoJet for the Delta Connection brand were also eventually re-leased by other Delta Connection carriers. As part of the announcement, all GoJet operated flights on behalf of Delta Air Lines were phased out by mid-2020. After the COVID-19 pandemic nearly reduced travel demand to zero bookings Delta Air Lines and GoJet Airlines agreed to terminate service early and park all remaining Delta Connection aircraft on March 31, 2020.

In April, 2020 Trans States Holdings closed GoJet's two sister airlines, Trans States Airlines and Compass Airlines, due to challenging economic issues and an unsustainable business environment related to the COVID-19 pandemic.
