Delta Airlines Cancellation Policy is designed to provide flexibility for passengers facing unforeseen circumstances. Travelers can cancel or change their reservations within 24 hours of booking without incurring any fees, as long as the booking was made at least seven days before departure. For non-refundable tickets, changes and cancellations are generally subject to fees, varying based on the fare class and the timing of the adjustment. Delta may also offer waivers for certain situations, such as medical emergencies. Passengers must review the specific terms of their ticket and be aware of any potential charges associated with cancellations or modifications.
