Southwest Airlines has announced a new partnership with Taiwan-based China Airlines, expanding its reach to Asia through an interline agreement. The collaboration was formalized at a ceremony in Texas, where both airlines committed to exploring deeper loyalty program integration.
Starting January 19, travelers will be able to book itineraries connecting Southwest flights from five major western U.S. airports—Los Angeles International Airport (LAX), Phoenix Sky Harbor International Airport (PHX), Seattle-Tacoma International Airport (SEA), San Francisco International Airport (SFO), and Ontario International Airport (ONT)—to China Airlines flights bound for Asia.
Initially, passengers can book trips involving both carriers on the China Airlines website. Within several weeks, similar bookings are expected to become available through select third-party travel sites such as Expedia. Once technical upgrades are complete, Southwest plans to allow these bookings—and eventually award redemptions—directly through its own website and mobile app.
