Dev blog 145 has mentioned the implementation of departure and arrival separation by having jetway entrances be 4 tiles wide. As seen here:

Personally, I do not think this is an optimal solution, as it requires placing a wall in the middle of the jetway, forcing asymmetry, and lots of escalators… It is clearly not how most people prefer to have their airports built, and would deter players from utilizing this option.
In dev blog 135 one way doors were mentioned as a feature of A35.
My suggestion is, that instead of having 4 tiles wide jetways, we could have a special type of door that lets through only arriving or departing passengers. it could have a runway exit like UI panel, with two sliders, one for direction and another a taxiway like UI panel for arriving passengers, departing passengers, or staff only (the doors should probably let staff pass through both ways regardless as they’re not arriving, nor departing).
This would enable more creative airport designs and be more user friendly.
Possible use case:
Have a hallway lining the gateside wall of the terminal. It would let departing passengers from the gate out along the wall, and would have arriving passengers crossing it from the boarding desk towards their gate.The hallway would be lined with those doors at openings preventing arriving passengers from using it to get to their gate, or departing passengers from entering the waiting hall.
Please write comments or criticism of my bold (?) idea here. Thanks,
