Overview
- Passengers will be able to book single-itinerary connections between Southwest’s U.S. network and Turkish Airlines’ flights to Istanbul with through-checked baggage.
- The tie-up launches via 10 shared U.S. gateways served by both carriers, creating multiple connection points for onward travel across Europe, Asia, the Middle East, and Africa.
- Tickets will be offered next year through Turkish Airlines, travel agents, and online travel agencies, with Southwest continuing backend work to add partner bookings on its own platforms.
- The arrangement is an interline rather than a codeshare, with no initial loyalty earning or redemption reciprocity confirmed.
- The deal is Southwest’s sixth overseas partnership announced in 2025 and comes as the carrier prepares a redesigned cabin with assigned and extra-legroom seating from Jan. 27, 2026.
