Delta Airlines allows passengers to make changes to their flights if their travel plans change. The airline's change flight policy varies depending on the type of ticket purchased, and additional fees may apply. Passengers with flexible fares may be able to make changes to their flights without incurring any charges, while those with non-refundable tickets may need to pay a fee and/or fare difference to change their flight. It's important to note that changes to flights are subject to availability, and passengers should check their ticket terms and conditions for specific details on Delta's change flight policy. If you need to make changes to your Delta Airlines flight, contact the airline's customer service team for assistance.
