Just fyi everyone that this topic has sort of been discussed in this thread here:
Where the baggage claim is (secured or un-secured) generally has to do with whether or not the airport is serving as a first point of entry to that country whereby bags need to clear customs additionally.
I believe from what I’ve read elsewhere that the devs actually already have an ‘International Baggage Claim’ in the game, but not yet available as a feature. I am not sure how accurate it is but I think it’s in the pipeline. That said, one way doors would be most helpful regardless
