Hello,
Airport City was declined some years ago due to invisible walls. Right now there is possibility to deactivate collisions for specific maps (like Freyfurt Modded), so Airport City can be added into MP. Driving with collision on this map isn't recommended.
Map has 8 day&night driveable lines with duration 10-60 minutes.
