how much time to cancel a delta ticket
Pay for the new flight with a credit card. When you click Purchase, you will receive a new confirmation number and itinerary. As of publication, Delta charges $150 to change domestic flights and $250 for international flights. Delta allows you to cancel any flight without penalty within 24 hours of purchase. If you need to make a change within the first 24 hours of purchasing a ticket, cancel the first itinerary and book a new, separate ticket to avoid the change fee. In general, you can only change the return portion of international flights.
