Delta Airlines Flight Change Policy offers a seamless and customer-focused experience. Within 24 hours of booking (for flights at least seven days away), changes are completely free—covering all fare types with only any fare difference due. After that, non‑Basic Economy tickets may incur fees ranging from $75 to $500 plus fare difference, while Basic Economy fares usually aren’t changeable. Changes can be made online via “My Trips,” the Delta app, by phone, or at airport counters, ensuring travelers can adjust flights with ease.
