Alaska Airlines launched the Atmos Rewards (formerly Mileage Plan) new-member offer. New members who successfully enroll by December 31, 2026 can receive a $25 or $50 flight discount code, depending on where you live. The code is issued within 72 hours of enrollment. To redeem it, you must complete booking on AlaskaAir.com within 28 days of joining, and travel must depart within 120 days of enrollment.
California and Hawaii residents can get a $50 discount by registering through a dedicated link.
Residents of all other states (except Alaska) can receive a $25 discount.
The offer is valid on Alaska Airlines, Hawaiian Airlines, and flights operated by Horizon Air and SkyWest (excluding round-trip routes involving Prudhoe Bay). The discount cannot be combined with other promotions, and rebooking may invalidate the discount. New members should review the terms and conditions carefully and use the offer in time.
