Makemytrip only believes in selling tickets. God forbid there may be a problem with your ticket due to any schedule changes or anything at all, do not expect any help from them. They will tell you that they are working on your issue when really they are doing nothing! It will be you calling them constantly, to hear the same reply over and over again. "We are working on it and will get back to you within 24 hours", and they never get back!
Any offers and promotions they advertise, they do not believe in fulfilling what they say. I had to threaten them with legal action before they finally responded with the free domestic tickets that I was to receive with my international return ticket. They will also keep hanging up on you when they can;t resolve your issues.
SO, UNLESS YOU ARE SURE SURE SURE that you will not be making changes to your itinerary or your airline will be nice enough to accommodate you elsewhere, DO NOT GO TO MAKEMYTRIP.I will rather pay $100 extra for a ticket elsewhere, then go to MAKEMYTRIP again and be harassed.
