Cleartrip is the better travel portal amongst others since it provides all flight details in a comprehensive manner. Booking is easy too and confirmation comes in an instant.
However, all the promotional stuff are bogus. I am yet to receive 25% cashback on my purchased ticket some two months back. The two for one and things like that have so many clauses that you will not get that. So, don’t go by their big talk, but if you have to book a ticket or a hotel have it clear in your mind that you’ll have to pay the fare/tariff as shown. You will get no discount on them.
But otherwise, the portal is good. I have been using it for quite sometime and don’t have any complaints since I don’t expect the freebies, which are anyway just gimmicks.
