Yes, Delta has a comprehensive cancellation policy. If you purchase a refundable ticket, you can cancel your flight anytime before departure without any fees, and you'll receive a full refund to your original payment method. For non-refundable tickets, cancellations can still be made, but you'll receive an eCredit for future travel, and a cancellation fee may apply, depending on the ticket type. Delta also offers a 24-hour risk-free cancellation policy allowing you to cancel any flight within 24 hours of booking for a full refund, regardless of the fare class, as long as the flight was booked at least 7 days before departure.
