Before asking Delta to close a SkyMiles account: nonexpiry is a different question
SkyMiles miles do not expire, but that does not protect them from account closure. A member's closure request is a listed closure ground; closure forfeits Medallion status, benefits and/or account miles.
Important unknowns
- The source does not establish the outcome of an individual request. Confirm current instructions with the airline; the effective date of these provisions is not established.
