I recently booked flight tickets to Hong Kong for my uncle from yatra.com and experienced ease and hassle free bookings.
Website is nicely designed to understand the itinerary of the flights. Multiple options are easily accessible and one can understand even if they are not regular in booking tickets online.
Yatra website drops down different airlines and timings as per customers requirement. We can also modify the search like the dates or destination from the same page rather going back and forth.
Payment procedure is smoothly driven. I believe it is secured as I personally did not find any issues in the payment. Once you create an account and book the tickets, they add some points to our account which can be redeemed on next travel sop that is a sight of small discount.
