Every major U.S. airline (except Southwest Airlines) typically charges penalty fees to change or cancel an economy fare flight. The fees can vary from as low as $75 on a domestic flight to more than $400 on an international flight.

The amount deducted for a flight cancellation depends on the fare class and the timing of the cancellation. In 2026, many global aviation authorities (like India's DGCA) have pushed for a "look-in" window, allowing passengers to cancel for free within 24 to 48 hours of booking, provided the flight is at least a week away. Outside this window, "Basic Economy" tickets are often non-refundable, meaning you lose the entire fare or receive a partial credit after a heavy fee (often $100–$200). For standard "Main Cabin" tickets, most major U.S. and European carriers have moved away from flat cancellation fees, instead allowing you to cancel for a "Flight Credit" of the full value to be used later. If you want a cash refund, you must typically purchase a "Fully Refundable" fare, which is significantly more expensive. In cases of medical emergencies, airlines may offer a credit shell or refund if provided with a valid doctor’s certificate, though this is at the airline's discretion.
