In normal times I have no doubt this is correct, only reason I ask is due to the current re-introduction of border controls even within the EU.

Sweden of course is not listed as one of these countries, so I think everything should be operating as normal, I am however looking for some confirmation that this remains the case.

And if not, will there be any type of check at the gate when boarding in Stockholm? I am concerned about entry restrictions since my fiancee is not an EU citizen, IATA and German documentation seems to indicate her entry would not be allowed (she is not EU citizen and currently has no residence permit for Germany, though she has one in Sweden).
