You can stack this 30% discount with 10% off buying Alaska Airlines e-mail gift certificates from Costco. You have to be a Costco member to buy $500 in Alaska Airlines credit for $450. Note of course that wholesale clubs are a Chase Freedom family 5x category this quarter, too.
Since this is 10% off the payment method as well as a separate discount on the fare, you don’t even lose out when you stack these, e.g. 30% off $100 is $70, and 10% off that would be just $63. But here you actually are buying Alaska tickets at 40% off, and can be earning 5x on the purchase to boot.
