Alaska Airlines and American Airlines have formed an alliance aimed at creating more choice for West Coast customers. As part of the expanded relationship, Alaska will join the oneworld alliance by summer 2021. Also, American will launch the first service from Seattle to Bangalore, India beginning in October. A new American route from Seattle to London Heathrow will begin flying in March 2021. The two carriers will continue their domestic codeshare that offers customers “hassle-free booking and travel” between the two networks. The codeshare will expand to include international routes for Los Angeles and Seattle. Alaska and American loyalty members will enjoy benefits across both airlines, including the ability to earn and use miles on both airlines’ full networks, elite status reciprocity and lounge access to nearly 50 American Admirals Club lounges worldwide and seven Alaska Lounges in the U.S.
