American Airlines has taken a measured step toward deeper ties with Taiwan’s Starlux Airlines. A new codeshare agreement, effective September 30, builds on an existing interline arrangement and lets passengers book certain Starlux-operated flights under American flight numbers. The change simplifies connections for travelers heading to Taiwan and several West Coast gateways.
Practical Changes for Travelers
Passengers will soon be able to purchase a single ticket that combines American domestic segments with Starlux long-haul flights to Taipei. Routes covered include Starlux service from Los Angeles, San Francisco, Ontario in California, and Seattle. In the other direction, Starlux flight numbers will appear on 26 American flights feeding into Los Angeles and Phoenix. The arrangement removes the need to book separate tickets or manage separate baggage claims for these itineraries. It also allows through-checking of bags to the final destination, a feature already available under the prior interline deal. American has not yet confirmed whether additional domestic flights will receive Starlux numbers in the coming months.
Starlux Background and Network
Starlux launched during the pandemic and operates a fleet of new Airbus A350 aircraft on its U.S. routes. The carrier offers both business-class and first-class cabins on these flights. It already maintains a codeshare with Alaska Airlines, allowing reciprocal earning and redemption of Atmos Rewards points. The airline continues to expand its U.S. presence, recently adding another Southern California route. Starlux has signaled interest in joining the Oneworld alliance, of which American is a founding member, though no formal application timeline has been announced.
Current Limits of the Partnership
The codeshare stops short of the deeper integration American maintains with partners such as Japan Airlines, Cathay Pacific, and British Airways. Travelers cannot yet earn or redeem American AAdvantage miles on Starlux flights. American elite members also will not receive priority boarding, lounge access, or upgrade consideration when flying Starlux. These restrictions reflect the early stage of the relationship. American has stated it will provide further details as the agreement rolls out.
What the Move Signals
The agreement gives American customers a more seamless path to Taiwan without requiring separate reservations. It also positions both carriers to test operational coordination ahead of any potential alliance membership for Starlux. Industry observers note that similar incremental steps have preceded fuller partnerships in the past. For now, the change primarily benefits travelers who value single-ticket convenience on routes linking the U.S. West Coast with Taipei. Further enhancements, such as mileage reciprocity or elite recognition, remain under discussion but are not part of the current rollout.
