First name: enter all your first name according to the passport.
Surname: enter all surnames according to the passport. You cannot abbreviate your names or enter them as initials only.
If you are getting married, you must book your trip in the same name that you will have in your passport when you travel.
If several passengers have identical first and last names (e.g. father and son), then a second first name must also be entered to distinguish them both.
Please make sure that you have filled in all details correctly. Note that the booking system removes all spaces and punctuation between names. These should not appear on the ticket.
We use international spelling for flight tickets, so some letters are changed after you have typed them in, as follows: Å becomes A or AA, Ä/Æ becomes AE, and Ö/Ø becomes OE. This matches the spelling in the machine-readable line in the passport.
