Do AAdvantage miles expire?
Yes. American AAdvantage miles expire after 24 months with no earning or redemption activity, and any qualifying activity resets the clock on the full balance. AAdvantage credit-card holders and members under 21 are exempt, so their miles stay alive however long the account sits idle.
GuideDo Alaska miles expire?
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.
ToolWhat are AAdvantage miles worth?
An American AAdvantage mile is typically worth about 1.5 cents — between the two US reference valuations, which disagree here — so 25,000 miles come to roughly $375. Cheap domestic economy lands nearer 1.2 cents and international business around 1.8 cents. The calculator converts any balance into dollars, pounds and euros.
GuideHow to earn AAdvantage miles
American AAdvantage members earn 5 miles per $1 on American Airlines fares, rising to 7, 8, 9 and 11 with Gold, Platinum, Platinum Pro and Executive Platinum status; basic economy earns none. Partner-airline flights earn by distance and cabin, and Citi points transfer in at 1:1, Marriott points at 3:1.

GuideCiti transfer partners

ToolWhat are Alaska miles worth?
An Alaska Atmos Rewards point, formerly a Mileage Plan mile, is typically worth about 1.5 cents, so 50,000 points come to roughly $750. Domestic economy lands nearer 1.25 cents, and business class on Alaska's oneworld partners around 1.8 cents. The calculator converts any Alaska balance into dollars, pounds and euros at all three rates.
ComparisonAvios vs AAdvantage miles
Avios and AAdvantage miles land close in value — about 1p per Avios against roughly 1.5 cents per mile — so the deciding factor is usually the cash charges, because a British Airways Avios reward adds carrier charges on top of tax. Avios expire after 36 months of inactivity; AAdvantage miles after 24.
