NEVER use makemytrip.com for any travel bookings. They are slow, unprofessional, and rest assured it will be a decision you will regret.
We booked tickets from India to NY , and had to cancel them later because of some health issues my mother had. The tickets got cancelled, but the refund still has not come through to our account. Its a fairly large amount, and we have paid the credit card company HUGE amounts of interest on the oustanding loan. Each time we call makemytrip, the customer service tell us that the refund should be through any time. It has been 2.5 months since this, and there is still no money in our account. I wonder if they plan to refund us at all or not.
In a nutshell, you will be doing yourself a great favour by not booking your tickets through makemytrip.
Pathetic service.They should be banned from operating.
