Just bought a flight with a discount, payed with my credit card and they just charged it and called me half an hour latter saying that my flight was not confirmed and that to confirm I would have to pay extra that would take my ticket above the normal marked price. Total planned scan. I have asked for them to cancel it and they said it was not refundable. Totally against the law. I had to cancel my card to get my money back. DO NOT FALL FOR THAT.
