Alaska Airlines Upgrades

Alaska's Atmos Rewards program offers complimentary status upgrades and milestone-earned upgrade certificates. Both target first class on Alaska and Hawaiian-operated flights, and both rely on U-class inventory availability.

Frequently Asked Questions

How do complimentary upgrades work on Alaska Airlines?
Atmos Rewards elite members are automatically placed on the upgrade waitlist when booking eligible economy fares (Y, B, H class) on Alaska or Hawaiian-operated flights. Upgrades clear based on U-class first-class availability and your tier priority. Titanium and Platinum get a 120-hour window, Gold gets 72 hours, and Silver gets 48 hours before departure.
What are Alaska Airlines upgrade certificates?
Upgrade certificates are earned as milestone reward choices at 85K+ status points in the Atmos Rewards program. They can be applied to any North American Alaska or Hawaiian flight with U-class availability and are shareable with non-elite travelers.
What does U-class mean on Alaska Airlines?
U class is Alaska's inventory bucket for first-class upgrade availability. When U-class seats are open on a flight, complimentary upgrades can clear and upgrade certificates can confirm. 2LNR monitors U-class inventory in real time across Alaska-operated routes.
Are Basic Economy fares eligible for upgrades on Alaska?
No. Basic Economy (Saver) fares in X class are excluded from complimentary upgrades. You need at least a regular Economy fare (Y, B, or H class) to be eligible. Award tickets (E, P, T, N classes) are also eligible.
