Momondo - A winner this time
 

I have been using Skyscanner for at least three years now, and have saved significant dollars with it. That is, until I heard about Momondo from Flyertalk and started searching through Skyscanner;Justfly AND Momondo.
My routing was to go to CCU; and I used airports such as IAD/Boston/ATL/ORD/JFK/EWR - planning to fly using points or a cheaper ticket from RDU to whichever airport we would fly out of. Business class was a must. And no crazy travel times. And, Momondo helped me find business seats, round trip from RDU-CCU for $2400. Route is RDU-EWR-DEL-CCU. Even though we are not flying until the summer, I got the tickets. And so glad I did - searches now dont even show the same itinerary. The cheapest option is $4700 per person. Skyscanner or any other sites didnt pick up this fare AT ALL....Momondo is the only one who showed it.
Just wanted to put this post out there so people searching or asking questions on the tools/sites can use this as reference.

Momondo has links to some of the shadiest booking sites in the world.

Use at your own risk.

Booked my flights - and it showing in UA/AI/Jet - with their reservation codes/was able to assign seats through each airline site - so hopefully things wont work.

Thanks to the OP for mentioning this. I'm finding it an interesting tool for pricing unusual destinations where I am not sure who serves them. I haven't bought thru the site but used results to know which airline sites to use.

+1 for Momondo, but as others have mentioned, be aware of who you're actually booking with.

I second, or third the "beware who you book with." I found a flight on Momondo, and the cheapest Agency was $50 cheaper than anyone else. I did a quick search on https://www.resellerratings.com/ and found the agency in question would call/email you later and say the flight was no longer available and then try and pull an upcharge on you.

Net, if you use Momondo, be sure to book from a reputable agent even if it costs more. Personally I use it to find the cheapest fare, then duplicate my search elsewhere (CheapOAir or Expedia etc) for booking.

ExploreTrip.com seems to be the lowest cost fare for a search I just did on Momondo. Here's their scary reviews:
