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!
Avoid school holidays: Many cheap airlines take advantage of school holidays to increase their prices, as they expect to have a larger number of passengers than usual. During these periods a late booking (1 week before departure) may result in your paying more than the price of a ticket with a regular airline. It is therefore advisable to avoid these periods, if possible.
