Delta Airlines Cancellation Policy permits travellers to cancel their bookings within 24 hours of booking for a full refund, as long as they book at least seven days before the flight's departure. If a cancellation is made after the 24-hour window for non-refundable tickets, the airline normally does not issue refunds, but the value of the ticket can be put towards future travel within a year, subject to change fees and rate fluctuations. Delta's policies, however, may differ according to the fare class and destination. When Delta Airlines cancels a flight, passengers are frequently rebooked on alternate flights at no additional cost.
