My experience: Essentially you book a flight at a bargain price and it seems all and good until they call you at a later time saying that "oh your flight couldn't go through, we need to rebook your flight". They then try and "rebook" your flight and the price goes up to something more like the market value of that flight. Basically a baiting scam but not sure if they actually steal your card information. Definitely do not book from them though.
