In 2026, obtaining a full refund from an airline depends heavily on the timing and the "fare class" of the ticket. Under many national regulations (like those recently updated by the DGCA in India), passengers can receive a full refund if they cancel within 24 to 48 hours of booking, provided the flight is at least 7 to 15 days away. Beyond this "look-in" period, full refunds are usually only granted for "Refundable" tickets, which cost significantly more. For "Non-refundable" fares, airlines typically only provide a travel credit (minus a fee) unless the airline cancels the flight or makes a major schedule change (usually 3+ hours), in which case you are legally entitled to a full refund to your original payment method. Always check the specific "Contract of Carriage" for your ticket to see the exact cancellation windows and refund triggers.
