What is the difference between refundable and non-refundable fares?

When you cancel a flight ticket, the airline charges a cancellation fee against your ticket. The amount that is returned after this deduction is called the refundable fare. For more information, please refer to the ‘Fare Summary & Rules’ under the ‘Flight Details’ tab. A non-refundable fare is a discounted fare where no refund can be claimed from the airline in case of cancellation.
