I'm confused. Do you mean from the food places? Those need proper extraction anyway. Or the cars/planes? Then mechanically ventilated airports take the air basically from outside anyway.

This is not how A/C works.

		Depends on whether an ERV/HRV or other fresh air intake system is involved, I guess. In a space like an airport with so many people, you do have to cycle in fresh air somehow, it can’t just be a sealed space.
