Alaska Airlines has added Canada's Porter Airlines as an interline partner, according to the airline. Members of Alaska's Mileage Plan loyalty program can earn miles by booking Porter flights through Alaska's website. The carriers plan to introduce in 2024 the ability to earn miles on each other's flights regardless of booking channel and allow some cross-carrier redemption, according to Alaska. Porter in January 2024 is set to launch service between Toronto and each San Francisco and Los Angeles.
