Tried several times to book online for my wife and I using my credit card. The airline website requires a security check, which I allowed. But the system concluded that card is stolen and refused my payment. I called Visa, they haven't received any request from the airline. I called the airline agents several times and beg them to contact their IT about the problem. They are not understanding and cooperative at all. Very frustating experience!
Pay by debit card: All cheap airlines charge customers a payment handling fee, which covers the costs they incur when accepting Credit Card payments. The fee may vary depending on the card circuit (Visa, Mastercard, Amex, Diners, etc) or the card type (Credit Card or Debit Card). Most of the time, if you pay by debit card you will be charged no payment handling fee or you will pay a lower fee than when paying by credit card.
