Delta Air Lines' SkyMiles program is one of the major US airline loyalty programs and a member of the SkyTeam alliance. A frequent question from members concerns the expiration of their miles.

Delta SkyMiles Expiration Policy

Delta offers one of the most straightforward and member-friendly policies when it comes to mileage expiration: Delta SkyMiles do not expire.

That's right! As long as your SkyMiles account remains open and in good standing, your miles will remain in your account indefinitely, regardless of how often you earn or redeem them. There is no requirement for periodic account activity to keep your miles valid.

This policy provides significant peace of mind for SkyMiles members, allowing them to accumulate miles over the long term without the pressure of needing to make transactions solely to prevent expiration.

Account Closure Considerations

While miles don't expire due to inactivity, like most programs, Delta reserves the right to close accounts under certain circumstances (e.g., fraud, program abuse, or sometimes prolonged inactivity if the balance is zero). However, your accumulated miles are safe from expiration as long as the account itself is maintained.

Official Policy

For confirmation and the official wording, you can refer to the Delta SkyMiles program rules:
