Delta and Alaska Airlines end frequent flyer partnership

From May 1, 2017, Delta and Alaska will no longer have a codeshare agreement, and customers of each airline will no longer be able to earn and redeem Delta’s SkyMiles or Alaska’s Mileage Plan frequent flyer miles on flights operated by the other carrier.

Mileage Earning and Redemption

Delta SkyMiles Members will be able to earn and redeem miles on flights operated by Alaska Airlines through April 30, 2017. SkyMiles Medallion Members will continue to receive their benefits when flying with Alaska Airlines through April 30, 2017.

Beginning May 1, 2017, SkyMiles Members will not be able to earn and redeem miles on flights operated by Alaska Airlines unless a ticket was purchased before Dec. 19, 2016. Medallion Benefits will not be available on flights operated by Alaska Airlines.

Delta is a member of the SkyTeam frequent flyer alliance, while Alaska does not participate in any major global airline alliances, but has codeshare agreements with several carriers that are members of global airline alliances.
