Southwest and China Airlines' partnership is an interline deal, offering joint itineraries to connect Asia and the U.S. on one ticket. Flights start in 2026.

Southwest's latest partnership with China Airlines was announced this week, when the two gathered at the International Air Transport Association's annual general meeting in India. The meeting is Southwest's first since becoming a member carrier earlier this year, and Southwest seems to be fully utilizing the networking opportunity.

Southwest Airlines Co. (NYSE:LUV) announced on Monday that it is in talks with China Airlines Group to create an interline partnership in early 2026. The airline company expects to start selling published connections with China Airlines later this year.
