"Your name must include all last names and first (given) name (given name in Sweden equal to "tilltalsnamn"). It is not needed to include all given names from the passport."
From systems perspective, it is best to have FirstName 1st (If you have multiple).
E.g. if my name is Thor Loki Odinsson (Where Thor is my "real" first name, then ticket only needs Thor Odinsson) .
If first "real" name was Loki, then there could be issues with other airlines/immigration, but SAS wouldn't care if ticket said Loki Odinsson.
Or any other airline except Egypt Air.
In my case my name is Loki Odinsson and my passport would say Thor Loki Odinsson - I use it on all my FFP and my tickets - no issues whatsoever except with Egypt Air.
