British Airways is to begin codesharing with Alaska Airlines on selected flights from the West Coast of the USA (Seattle, San Diego, San Jose, and San Francisco) to destinations in North America with effect from 23 November 2016.
Whilst BA already has an extensive codeshare with American Airlines across North America, these additional codeshares do provide additional one-stop options, especially where American Airlines has a relatively small presence.
The routes covered by the codeshare are as follows:
San Diego to Portland and Salt Lake City;
San Francisco to Anchorage, Portland and Salt Lake City;
San Jose to Portland, Santa Ana;
Seattle to Honolulu, Kona, Kahului in Hawaii; Portland, Salt Lake City, Boise, Fairbanks and Spokane.
Note that due to regulatory restrictions, these codeshare flights can only be booked when connecting from a British Airways operated flight to/from London. They cannot be booked individually.
Further codeshare routes may be announced in due course (particularly in light of the fact that Alaska Airlines is in the process of merging with Virgin America) and codeshare flights are on sale now at ba.com
