Delta Airlines Flight Change Policy
Delta Airlines Flight Change Policy allows passengers to modify bookings easily online, via phone, or at the airport ticket counter—with changes free within 24 hours of booking (for trips scheduled at least seven days out). After that, change fees apply depending on fare type and route—ranging from $0 for refundable fares to up to $500 for non‑refundable ones—plus any fare difference. Same‑day changes are permitted on U.S. mainland routes, excluding Basic Economy and many international tickets
