Do Marriott points expire?
Yes. Marriott Bonvoy points expire after 24 consecutive months of account inactivity. Any qualifying activity — a stay, a card purchase that earns points, or a points transfer — resets the 24-month clock on the whole balance. There is no fixed expiry date, so an active account never loses points to time.
GuideDo 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 Amex points expire?
No. American Express states Membership Rewards points have no expiration date, and there is no inactivity rule. They are forfeited in two situations: closing your last Membership Rewards-earning Card loses unredeemed points immediately, and points can also be forfeited for an unpaid billing period.
GuideAmex to Avios
American Express Membership Rewards points transfer to Avios at 1:1, so 10,000 points become 10,000 Avios. Transfers are usually instant once your Avios account is linked, though Amex asks you to allow up to 72 hours. Periodic transfer bonuses of roughly 15 to 30 per cent are the easiest way to boost the rate.
ToolWhat can my points do?
Add your Amex Membership Rewards to your Avios, since they transfer to British Airways at 1:1, and compare the total with off-peak reward prices. A New York–London economy return is 55,000 Avios and business 176,000. The tool sorts trips into within reach now, one transfer away and not yet in reach.
ToolWhat are Marriott points worth?
A Marriott Bonvoy point is typically worth about 0.73 cents, where the published valuations cluster after the 2026 devaluation, so 50,000 points come to roughly $365. Low-category rooms land nearer 0.6 cents and high-end properties around 0.89 cents. The calculator converts any balance into dollars, pounds and euros.
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.
GuideHow to earn Marriott points
Marriott Bonvoy members earn 10 points per $1 at most of its hotels — 5 at Residence Inn, TownePlace Suites and Element — plus an elite bonus from 10% for Silver to 75% for Titanium and Ambassador. Marriott's co-brand cards earn up to 6 points per $1 at Marriott, and US Amex, Chase and Bilt points transfer in at 1:1.
GuideAmex transfer partners
US American Express Membership Rewards points transfer to 16 airlines and 4 hotel programs. Most airlines, including Delta, British Airways, Air Canada Aeroplan and Flying Blue, are 1:1; Cathay Pacific, Emirates and JetBlue are 5:4, Aeromexico 1:1.6 and Hilton 1:2. UK Membership Rewards has its own list, with Emirates at 2:1 and Marriott at 2:3.
ComparisonAvios vs Amex Membership Rewards
Hold Membership Rewards until you have an Avios booking in mind. Amex points transfer to Avios at 1:1 and never expire while you keep an MR-earning Card, so they are the flexible form of the same value. Avios lapse after 36 months of inactivity and can only be spent in Avios programs.
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.
