Do Skymiles expire?

SkyMiles earned through the Delta SkyMiles Program do not expire as long as there is activity in the account at least once every 24 months. This activity can include earning miles through flying, using a SkyMiles Credit Card, or redeeming miles for flights or other rewards. If there is no qualifying activity within a two-year period, the miles may expire, and the account could become inactive. It is important for members to stay engaged with their accounts to ensure that their hard-earned miles remain valid. Members may want to regularly check their account status and consider making a small transaction if they are close to the expiration threshold.
