Delta Airlines allows passengers to cancel their flight bookings within 24 hours of purchase without any cancellation fees, as long as the flight is scheduled to depart at least seven days later. This applies to all fare types, including non-refundable Basic Economy tickets. If canceled within this 24-hour window, passengers receive a full refund to their original payment method. After the 24-hour period, cancellation policies depend on the ticket type. For Main Cabin, Comfort+, First Class, and Delta One fares, Delta has removed cancellation fees, and canceled tickets are usually issued as eCredits valid for one year if the ticket is non-refundable. Refundable tickets can be canceled at any time before departure for a full refund. Basic Economy fares are more restrictive: after 24 hours, these tickets cannot be changed or refunded unless Delta makes significant schedule changes or issues travel waivers due to weather or operational disruptions. For award tickets booked with SkyMiles, cancellations are generally free for domestic travel, while some fees may apply for international trips unless the passenger has elite status. In cases of significant delays or cancellations caused by the airline, passengers may be entitled to a full refund if the delay is over three hours domestically or six hours internationally. Refunds are processed back to the original form of payment, usually within seven business days for credit cards or up to 20 days for other methods. Passengers can manage cancellations and request refunds through Delta’s website, app, or customer service. Overall, Delta’s cancellation policy offers flexibility with a risk-free 24-hour cancellation window and varying options depending on fare class, aiming to accommodate different traveler needs.
