If you have a Refundable ticket, +𝟣-𝟪𝟪𝟪-𝟤𝟨𝟩-𝟫𝟧𝟧𝟣 you can get a full refund when you cancel, at any time before departure. If you have a Non-Refundable ticket and cancel outside the 24-hour risk-free window , you’ll generally receive an eCredit instead of a refund.

What is the last possible time to cancel a Delta flight?
You can cancel a Delta flight +𝟣-𝟪𝟪𝟪-𝟤𝟨𝟩-𝟫𝟧𝟧𝟣 up to the time of departure. However, cancellations made closer to departure time may limit your options for rebooking, and non-refundable tickets may only offer an eCredit for future use.
