Typically I use hipmunk to quickly figure out what good connections and good prices are. Recently I saw that "unknown" websites like farestore or travelmerry are the lowest bidder by a huge margin.
Example: Boston<->London Aug/7-Aug/12 the "cheap" websites show prices that on "good airlines" (British, Lufthansa, Swiss) that are about half (or even less) what you find on "normal" websites (Expedia, Kayak) or at the airline. The price difference was drastic: 1000$+.
The cheap flights seem to be bookable, i.e. can get to the point where I type in my name and my credit card (which I didn't do).
Has anyone used these before? Are there for real or is this some sort scam?
P.S.: all these cheap sites all seem to have the logo "powered by skyscanner", getawayasap seem to be another of these sites
