American continually evaluates its partnerships with other airlines and given the evolution of the Alaska Airlines network, we are making changes to the frequent flyer benefits offered for travel on Alaska including elite benefits and mileage accrual effective January 1, 2018.
Alaska remains a valued partner, and AAdvantage members will continue to earn miles when traveling on American marketed flights operated by Alaska or Horizon Air. Mileage redemption is not changing and AAdvantage members can continue to book award travel on the entire Alaska Airlines network.
