Momondo is an amalgamation of few travel services like airlines search, destination info etc. This site does not sell anything, just provides information. The good thing is all this info comes free! The info are presented in few search formats comes with name, address, map etc.
Momondo was conceptualized by few people from the travel industry and is based in Denmark. They provide search for flights, hotels, car rentals and city guides. The site provides info in 14 languages. The is good even in terms of India related info. However, it may not be upto the mark for city guide for India. The best is their flight search and there are words on the net that, Momondo probably provides the lowest airlines fare search.
I see that they have words of quality from The New York Times, CNN etc. So try Momondo to your advantage.
