As of early 2026, Delta Air Lines maintains a very flexible policy for most SkyMiles award tickets. For travel originating from the United States and Canada to any destination worldwide, award tickets are essentially fully refundable; you can cancel your flight at any time prior to departure and have the miles redeposited into your account and the taxes/fees refunded to your original form of payment without a redeposit fee. However, there is a major exception: Basic Economy award tickets are generally non-refundable and non-changeable after the risk-free cancellation period (24 hours after booking). For travel originating outside of the U.S. and Canada, some fees may still apply depending on the specific region and fare type. Always ensure you cancel at least before the "gate closes" to avoid being marked as a "no-show," which could result in the forfeiture of your miles. This policy makes Delta one of the more flexible carriers for frequent flyers who need to book speculative trips using their mileage balance.
