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!
Estimate your luggage well: As cheap airlines are trying to minimize their costs they usually have a restrictive luggage policy. - You can board the plane with only one piece of hand luggage (usually not heavier than 10kg and with maximum dimensions of 55x40x20cm). For detailed information on hand luggage allowance check the website of the carrier. - If you plan to also take hold baggage with you, you will need to pay for it online (when you book your ticket) or at the airport. Keep in mind that it is cheaper to pay for your checked-in luggage online than at the airport.
