Southwest Airlines has joined the International Air Transport Association’s Schedule Data Exchange Program (SDEP), bringing the total number of participating airlines to 190.
The SDEP, launched in late 2023, establishes a single airline-owned database containing schedule information and minimum connection time exceptions. This addition expands the program’s data pool, supporting more informed decision-making across the aviation industry.
Southwest, a U.S.-based carrier with IATA code WN and a fleet of 753 aircraft, operates as a scheduled airline founded in 1971. Its participation aligns with efforts to enhance schedule data sharing among carriers.
