This site is cheating the people. I got coupons from them since I got a ticket from another website which was cheaper than travelocity but in no circumstance can I use them. If we read carefully the terms and conditions, they have written that the coupons can be used to book tickets only on travelocity.co.in but the real fact is that all their tickets are routed to another website called riyaconnect.com.
Hence, you will not be able to use these coupons anyhow. They would have been sued if they did such a thing in US.
