If an airline refuses to refund you in 2026, your first step should be to cite the specific consumer protection laws relevant to your region, such as DOT (USA) or EC 261/2004 (EU). If the airline canceled the flight or made a significant schedule change, you are legally entitled to a cash refund, not just a voucher. If the "front-line" customer service agent refuses, ask for a written explanation of the denial. Your next move is to file a formal complaint with the national aviation authority (like the FAA in the US or the CAA in the UK). In early 2026, several countries like India (via the DGCA) have introduced new rules requiring refunds within 14 days; mentioning these specific mandates can often "unstick" a stubborn claim. If the airline remains unresponsive, you can initiate a credit card chargeback (Fair Credit Billing Act) if the service you paid for was not provided. Finally, for persistent issues, many travelers now turn to "claims agencies" or "Air Passenger Rights" companies that handle the legal paperwork in exchange for a percentage of the settlement, ensuring you get at least part of your money back from a reluctant carrier.
