Yes, in 2026, you are generally entitled to a full refund in the original form of payment if the airline makes a "significant" change to your flight schedule and you choose not to travel. Under updated 2026 aviation consumer protection rules (like those from the US DOT and recent DGCA updates), a "significant" change is typically defined as a departure or arrival time change of more than 3 hours for domestic flights or 6 hours for international flights. This applies even if you purchased a non-refundable ticket. The airline must offer you the refund rather than just a travel credit or voucher, though they will often try to push the voucher first. If the new schedule no longer works for your plans—for example, you’ll miss a cruise or a wedding—you have the right to reject the change and demand your money back. Always check the specific "Contract of Carriage" for your airline, but federal law usually supersedes their internal policies.
