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.
