Delta Air Lines has a structured cancellation policy that depends on the fare type you’ve selected. For most non-refundable tickets, Delta does not offer a cash refund upon cancellation. Instead, the value of the ticket is converted into a travel credit, minus a cancellation fee. This credit is typically valid for one year from the original purchase date and can be used toward future Delta flights. The exact cancellation charge varies depending on the route and ticket class. However, one of the most traveler-friendly features Delta offers is a 24-hour risk-free cancellation policy. If you cancel within 24 hours of booking and your flight is at least seven days away, you will receive a full refund with no fees, regardless of the fare type.

If you’ve purchased a refundable ticket, you can cancel at any time without penalty. In this case, you’ll receive a full refund to your original form of payment. This option is ideal for travelers who may need to adjust plans without worrying about cancellation charges.

For further help or to process a cancellation, you can contact Delta’s customer service at 1-866-838-4934. It’s a good idea to have your booking details ready before calling. Whether you're looking to cancel within the 24-hour window or need guidance on how to use your travel credit, calling 1-866-838-4934 will connect you with a trained agent who can assist with your request.

Frontier Airlines also has a straightforward cancellation policy, though it's more restrictive than Delta's. For non-refundable tickets, you generally won't get a cash refund. Instead, Frontier may issue a travel credit, which must be used within 90 days. There is often a cancellation fee applied, especially for changes made close to the departure date. The closer you are to the flight date, the higher the potential fee.

If you cancel within 24 hours of booking and your flight is at least seven days away, Frontier does offer a full refund—even on non-refundable fares. Refundable ticket holders can cancel at any time and receive a full refund without penalties.

To cancel a Frontier flight or ask about refund options, you can reach Frontier’s customer service at 1-866-838-4934. Have your flight information ready to speed up the process.
