As of 2026, Delta Air Lines maintains one of the most flexible refund policies in the industry for award tickets booked with SkyMiles. For travel originating in the United States or Canada, award tickets (excluding Basic Economy) are fully refundable up to the time of departure. If you cancel your trip, your SkyMiles will be redeposited into your account immediately, and any taxes and fees paid will be refunded to your original form of payment. There are no longer "redeposit fees" or "cancellation fees" for these standard award bookings. However, there are two critical caveats: First, Basic Economy Award Tickets are generally non-refundable and cannot be changed, though they may sometimes be canceled for a significant mileage fee. Second, for international travel originating outside of North America, different rules and fees may still apply depending on the local market regulations. For the vast majority of domestic travelers, this policy makes SkyMiles a "risk-free" way to book travel, as you can cancel and get everything back even on the day of the flight if your plans change.
