Guide

Do Delta miles expire?

No. Delta SkyMiles do not expire and there is no inactivity clock — Delta's own program rules state miles never expire. The catch is value rather than time: SkyMiles are priced dynamically against cash fares, so a balance held for years quietly buys less as fares and award prices rise.

Guide

Do 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.

Guide

Do 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.

Guide

Do Chase points expire?

No. Chase Ultimate Rewards points do not expire while the card account they sit in stays open, and there is no inactivity clock. Closing the card forfeits them, so move them to another Ultimate Rewards card or redeem them before you close it; an account Chase closes for missed payments forfeits them too.

Guide

Amex 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.

Guide

Guide

How to earn Delta miles

Delta SkyMiles members earn 5 miles per $1 on Delta fares, rising to 7, 8, 9 and 11 with Silver, Gold, Platinum and Diamond Medallion status; Basic Economy earns none. Partner-airline flights earn by distance and cabin, American Express points transfer in at 1:1 and Marriott points at 3:1, and dining, Uber and shopping add more.

Guide

Do Nectar points expire?

Not on a date, but you can still lose them. Nectar points carry no expiry date, yet Nectar may close an account with no points earned or spent for 12 months in a row — and the points are lost with it. Scanning your Nectar card or app at Sainsbury's, Argos or eBay once a year keeps the balance safe.
