In 2026, passenger rights regarding refunds have been strengthened by new regulations in the U.S. and recent court rulings in the EU. In the United States, a Department of Transportation (DOT) rule mandates that if an airline cancels your flight for any reason and you choose not to accept rebooking or travel vouchers, you are entitled to a full cash refund to your original form of payment. This must be processed within seven business days for credit card purchases. Similarly, in the European Union under Regulation EU261, if a flight is cancelled, the airline must offer a full refund of the ticket price, including taxes and service fees. A landmark 2026 EU court ruling even confirmed that airlines must refund the booking fees charged by third-party travel agencies (like Expedia or Opodo) if the flight is cancelled. It is important to remember that you must explicitly decline the airline's offer of a voucher or "flight credit" to receive the actual cash refund you are legally owed.
