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.
Non-Refundable Tickets and Change Fees. Changing a non-refundable ticket is relatively simple, and in most cases, you are usually allowed a year to rebook travel. However, there is a catch: changing most non-refundable tickets will cost you a steep change fee ranging from $30 to $150 (and the more expensive price is more common). Plus, if the price of airfare to your destination rises for the future time period you change your ticket to, you will also have to pay the difference.
