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!
Weigh your luggage at home: Avoid excess baggage charges by weighing your luggage at home and trying to stay under the weight limit (15 or 25 kilos per checked-in bag, depending on the airline). If you exceed the weight limit, you may be asked to pay 10-15E per extra kilo. If your luggage is overweight and you can't leave anything else at home, it may be a good idea for you to take a hand baggage. But be careful: you need to check the weight limits for your hand luggage too!
