Do Alaska miles expire?

No — Alaska miles no longer expire. Alaska dropped its 24-month inactivity rule in 2023, and the program (now Atmos Rewards) keeps your balance indefinitely. Here's why a balance that never lapses can still be quietly wasted.

Short answer

No. Alaska dropped its 24-month inactivity rule in April 2023, and under the renamed Atmos Rewards program the terms state points have no expiration date and may remain in an account indefinitely. An idle Alaska balance is safe, so the only real risk to it is program devaluation.

Key takeaways
  1. Alaska miles don't expire. The old 24-month inactivity rule was dropped in April 2023.
  2. There is no clock to reset. Atmos Rewards, the renamed Mileage Plan, lets points remain in an open account indefinitely, and the miles you earned under Mileage Plan are the same balance.
  3. Sign in under the Atmos Rewards name, confirm the account is still open, and price a trip with what's there.

What changed in April 2023

No — Alaska miles do not expire. Alaska removed its old 24-month inactivity rule in April 2023, and the current program — Atmos Rewards — states that points do not have an expiration date and may remain in your account indefinitely, as long as the account is open. The miles you earned under Mileage Plan are the same balance. There's no inactivity clock to beat anymore; the only real risk is forgetting a balance that never forces your hand.

Alaska joined the no-expiry airlines. Who didn't?

The windows are not the same across programs, and several of the biggest have no window at all. Where a rule below differs from the one you remember, it is because the program changed it: Hilton doubled its window, and Alaska, Southwest and United each dropped theirs outright.

Alaska miles expiry — common questions

No. Alaska miles no longer expire. Alaska dropped its old 24-month inactivity rule in April 2023, and the program — now Atmos Rewards — states that points do not have an expiration date and may remain in your account indefinitely while the account is open.

Sources & method

Every window on this page is read from the program’s own published terms, or from a source that quotes them, and recorded in one file with the date it was checked — so a figure here and a figure anywhere else on Nanvero are the same figure. Where a program has changed its rule the old value is not quietly overwritten, as with Hilton’s move from twelve months to twenty-four. The whole expiry cluster works from the same table.

Where these numbers come from: Alaska Airlines “Atmos Rewards points do not have an expiration date and may remain in an account indefinitely”; the old 24-month rule was dropped in April 2023 (September 2026). Programs change these rules, so we re-check them and date what we find. Confirm against your own account before relying on a deadline.

Miles that last, finally used.
