Do Alaska airlines miles expire? Mileage Plan miles do not expire as long as there is qualifying account activity at least once every 24 months. Qualifying account activity includes earning or redeeming miles on Alaska Airlines or one of its partners, such as using the Alaska Airlines credit card, flying with Alaska Airlines, or making a purchase with one of their partners. This policy provides flexibility and peace of mind for Mileage Plan members, as they can continue to accumulate miles without the worry of them expiring. Additionally, the Mileage Plan program offers various opportunities to earn and redeem miles, including flights, car rentals, hotel stays, and more, making it a valuable and versatile loyalty program for frequent travelers.
