Feature request title:
Like in real life when a plane comes from another country the passengers will go through a special walkway that leads them to Customs. The boarder agent will scan their passport to have record they entered the country. This would add realism and would be great when they add multi floors. We could have a new zone called the international zone which is where the passengers walk through. Also we could put remote stand bus stops at a ground level entrance for the passengers coming from the remote stands.
Why it should be implemented:
It would add a fun new challenge to the game and would make it more realistic.
