Yatra.com is really a beautiful website for booking online tickets for airways, hotel & Trains also.
I have booked various online tickets through it, but the best event was when it gave me a 25% special discount offer for booking a train ticket.
I saved rs. 500 through it. I hope more offers of these types will come in future.
Also there service is faster as compared to the other online services like this.
I like Yatra.com & recommend all to try it once.
