Do I have to write all the names shown in my passport in my booking?

Yes. When you make your reservation, you must write all the names included in your passport or identity card. Airlines have strict requirements for security, and it is crucial that you enter all passengers' names exactly as they appear in their formal documents. Airlines usually do not permit any name change or ticket transfer. If you incorrectly enter a name, you risk having to buy a new ticket, without getting your money back.
