The “West Coast International Alliance” will allow travelers to codeshare on both airlines, which means it will be easier to book flights across the two networks. This alliance includes international routes from Los Angeles and Seattle.

The alliance also means you can now earn loyalty points across the two airlines as well.

American Airlines is planning to set up Seattle as an International Gateway by adding first-ever direct international flights to Bangalore, India and London Heathrow.

“Alaska has always been proud to serve Seattle, the city that we call home. We’re thrilled to give our guests more choice, broader use of loyalty benefits, and seamless global service with American and oneworld,” said Ben Minicucci, president of Alaska Airlines. “Additionally, international service to global business and tech hubs Heathrow and Bangalore is a tremendous win for the growing Seattle region and the West Coast.”

The new alliance will allow travelers on either airline access to more than 1,200 destinations worldwide.
