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.
