I have been using Makemytrip for quite a long time, I use both the website and the app both provide quite the same functionality which is quite rare as most of the apps are don’t match the websites functionality, I have used Makemytrip only for ticket booking so my review is only about that and I would like to mention that I have never faced any issues with them so my review is mainly for things other than those,
Makemytrip user interface is very intuitive and it has all the possible sorting features to select the flights tickets to match the requirements and the fare calendar is very useful if we have flexible travel dates, it clearly states which flights are hand baggage only or Otherwise,
Its helps creating accounts with IRCTC which is very useful considering how impossible it is to recovery your lost IRCTC accounts,
The only problem I have with them is the transaction fee they charge for making any flights booking payment Which is quite high at Rs.200
