Refundable tickets can be returned for a refund to your credit or debit card or allow you to make changes to your travel plans. If Make My Trip Customer Service has processed a refund for you, it will take, on average, three to four billing cycles to process (about 90-120 days). Non-refundable tickets cannot be returned for a refund. However, if you cannot use your ticket, you may be able to apply its value toward a future flight within specified time frame as per the rules of the airlines. The airline may charge additional fees for changes made to a non-refundable ticket.
Refund rules of e-tickets are the same as paper tickets. Refund application of an e-ticket is easier than the paper ticket. If the paper ticket is lost for which the refund is requested, firstly lost ticket procedure has to be completed for the refund.. Itinerary Receipt, which is given to you at the time of ticketing, is a travel document which confirms all ticket data for both reservation and flight, so you do not need an extra paper ticket for confirmation.
