You can determine if your flight is non-refundable by checking the "Fare Rules" or "Conditions" section of your e-ticket or booking confirmation. Most budget-friendly fares (Basic Economy, Saver, or Promo) are explicitly labeled as "Non-Refundable," though they usually allow for a "Credit Shell" or "Future Flight Credit" if you cancel before departure. In 2026, the DGCA in India and the U.S. DOT have enforced stricter transparency; airlines must now clearly display the refundability of a fare during the booking process. Another key indicator is the "Look-in" or "Cool-off" period: in many regions, you are legally entitled to a full refund within 24 to 48 hours of booking (provided the flight is not departing immediately), regardless of the fare type. If you see a "Cancellation Fee" that exceeds the base fare, it is likely a non-refundable ticket where you would only get back government taxes and airport fees. For the most accurate check, log into the airline's "Manage Booking" portal and look for the "Cancel Flight" option to see the calculated refund estimate.
