Delta Airlines provides a cancellation policy designed to offer travelers both flexibility and peace of mind. Refundable tickets can be canceled at any time, with the option of a full refund. If you’ve purchased a non-refundable ticket, cancellation is still possible, though you may be issued a credit toward future travel instead of a refund. In addition, Delta has a 24-hour risk-free cancellation policy that applies to all tickets booked at least seven days before departure. This means you can cancel or make changes without incurring penalties within the first 24 hours of booking.
