After you purchase your ticket, they call you to tell you that the flight you just booked is sold out. Then tell you that you will have to pay an additional price to book you on another flight.
Complete scam! I thought it was a legit site and used my card to purchase the ticket, I had to cancel my card as the scammers now had all of my card information, to include email and phone number. To be safe changed everything. Complete mess. BEWARE
