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 Hilton points expire?
Yes. Hilton Honors points expire after 24 consecutive months without eligible activity — the rule was 12 months until Hilton doubled the window. Any stay, card spend or points purchase resets the clock on the whole balance. Points never expire on a date; only inactivity loses them.
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.
ToolWhat are Hilton points worth?
A Hilton Honors point is typically worth about 0.4 cents after two consecutive devaluations, so 100,000 points come to roughly $400. Low-demand rooms land nearer 0.35 cents and aspirational resorts around 0.5 cents. The calculator converts any Hilton balance into dollars, pounds and euros at all three rates.
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.

ComparisonMarriott Bonvoy vs Hilton Honors
A Marriott Bonvoy point is worth more than a Hilton Honors point — about 0.73 cents against 0.4, per the published US valuations — so a Hilton balance has to be roughly twice the size to buy the same night. Both expire after 24 consecutive months of inactivity. Compare a specific night in cents per point, not balances.
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.
