Booked a low demand flight from Florida to Tennessee. The flight price was less than baggage price. Once booked, I started receiving calls and texts that there was an issue and they needed to charge me $54 more. Explained to the (overseas) man this is their problem, not mine as the charge has hit my card and a contract has been initiated. He wanted to argue but I told him to figure it out and live up to the agreement and hung up. About 10 minutes later a text came through that they would "pay the difference". I have no idea how lawmakers could allow a company like this to operate. Review after review indicates illicit activity on their part. I am not sure why Kayak has a link to their site from theirs but it tarnishes the Kayak brand by allowing or being affiliated with this scam. If your card has a pending charge against it do not pay additional amounts or being tricked into buying insurance from Cheapflights - the better move is to not use Cheapflights at all,
