Alaska Airlines and American Airlines are ending their long-term frequent flyer partnership. Starting March 1, 2020, the reciprocity agreement that allowed members of both rewards programs to book flights on either American Airlines or Alaska Airlines flights will end. Specifically:

  • Alaska Airlines Mileage Plan members will no longer be able to redeem miles for American Airlines flights.

  • AAdvantage members will no longer be able to redeem miles for Alaska Airlines flights.

Deadlines for booking award travel

Mileage Plan members can still redeem miles for flights on American Airlines through Feb. 29, 2020. Travel must also be completed by that date. Past that date, Alaska Airlines will no longer be able to accommodate changes, except for cancellations.

AAdvantage members may still book award tickets on Alaska Airlines through Feb. 29, 2020. Ticket changes will not be permitted after that date.

Deadline for earning miles

Alaska Mileage Plan members will continue to earn miles on domestic American Airline flights marketed by Alaska. Mileage Plan members who booked international flights operated by American before Oct. 2, 2019, can still receive miles if they submit a mileage credit request after the completion of the flight.

Flights booked on or after Oct. 2, 2019, must be completed by Feb. 29, 2020, to be eligible for Mileage Plan miles. For more information regarding specific flights, visit this page.

What isn’t changing

The updates to mileage earning and redemptions doesn’t mean that the relationship between Alaska and American Airlines is completely finished. The two airlines will continue to have a code-sharing agreement for certain flights to the East Coast, Midwest and Canada. AAdvantage members will also still be able to earn miles while flying on code-share flights.

Frequent flyers will also retain reciprocal access to each of the airline lounges. The rules remain the same as before, meaning you must be flying on American or Alaska Airlines that day and meet access requirements.

The bottom line

This isn’t the first time the two airlines have adjusted their partnership. In early 2018, the companies reduced their reciprocal benefits, including things like priority boarding and free checked bags.

Alaska Airlines continues to maintain a robust international airline partnership with airlines that include British Airways, Cathay Pacific, Finnair, JAL, LATAM and Qantas.
