Delta Airlines has a cancellation policy that varies depending on the type of ticket purchased. Passengers can cancel their booking within 24 hours of purchase and receive a full refund as long as the flight is scheduled to depart at least 24 hours later. This applies to all ticket types booked directly through Delta. Refundable tickets can be canceled at any time before the flight for a full refund with no fees. Non-refundable tickets can be canceled before departure, but instead of a cash refund, passengers receive a travel credit to use on future flights. Delta has removed change and cancellation fees for non-refundable tickets originating from North America. Basic Economy tickets are the most restrictive and cannot be changed or refunded after the 24-hour cancellation window unless Delta changes the flight schedule by more than an hour. Award tickets booked with miles can be canceled without penalty for domestic flights, but international award tickets may have fees unless the passenger has elite status. Delta may also offer travel waivers during major disruptions like severe weather or strikes, allowing fee-free cancellations or changes. Cancellations can be made online through Delta’s website, via their mobile app, or by calling customer service. It is important to cancel before the scheduled departure to avoid losing the ticket value. Overall, Delta’s policy provides flexibility with refundable tickets and a 24-hour risk-free cancellation period while offering credits for non-refundable fares.
