Southwest Joins IATA Schedule Data Exchange Program

Southwest Airlines has joined IATA’s Schedule Data Exchange Program (SDEP), bringing the number of contributing airlines to 190.

The SDEP was launched in late 2023 to build a uniquely airline-owned schedule and minimum connecting time exceptions database. Schedule data underpins many aspects of an airline’s business, including network planning, slot coordination, and interline agreements. Data coverage now exceeds 70% available seat kilometers (ASKs) of airlines based in Asia, Middle East, and Africa, and is expected to reach 90% coverage globally by end of 2026.
