Do United miles expire?
No. United MileagePlus miles do not expire; United dropped its 18-month inactivity rule in August 2019 and has not reinstated it. A balance survives an idle account indefinitely. What it does not survive is devaluation — United prices awards dynamically, so miles held for years tend to buy less.
GuideDo Southwest points expire?
No. Southwest Rapid Rewards points do not expire while your account stays open — Southwest removed points expiration in 2022. The one thing that loses them is closing the account: Southwest's terms say points in a closed account are terminated, so leave it open even if you stop flying.
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.
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.
GuideHow to book United awards
United has no award chart: miles prices move with demand and the cash fare, and the cheapest are limited saver seats. Since April 2026 primary United cardmembers pay at least 10% fewer miles on United flights. Awards can be changed or canceled free before departure, and Star Alliance partners can be booked with the same miles.
