If you cancel your flight within 24 hours of booking your Delta Air Lines airline ticket, you are eligible for a full refund, according to Delta's cancellation policy. This is referred to as the "24-hour refund policy". There are certain crucial details you need to be aware of if you purchased a Delta Air Lines flight ticket through Alternative Airlines. You may cancel your reservation within 24 hours of your purchase.Please be aware that we might not be able to honour the 24-hour cancellation policy if you contact us outside of business hours to cancel your Delta Air Lines ticket and the window has already passed by the time we get your refund request. This is because Delta won't allow us to issue the refund.
