You don't need 20 tiles to serve the small gates, and thus could run conveyors on the ground floor behind a wall, saving cost over running them on B1 - which would require additional foundation. The flight planner uses a drag-and-drop system for scheduling flights. An Air Traffic Control Tower is required to schedule flights and accept General Aviation flights. It can be accessed through the UI on the lower left corner of the screen during normal gameplay and by using the shortcut 'F'. Stacking this way will allow you to maximize your facilities in the minimal amount of floor space. The flight planner is a feature of the game used to schedule flights signed through contracts. Say you have a "Pier" that is 20 tiles wide, serving small gates on one side (thus boarding from the ground floor) and large gates on the other side (boarding from the 2nd floor).
You can save even more if you run conveyors on the Ground level beneath gate services you may have on L2 (since you have to have foundation on G to support it). This design technique would save a LOT of money in construction. You can have a hub serving two baggage depots at the end of your piers. So, four tiles wide for foundation running between hubs.

All you need is to have one tile for worker access (and this may not be necessary anymore), plus a tile for a two-way conveyor, and then two walls. You've built HUGE amount of foundation on B1 to support this baggage system, and it isn't necessary. I'm not opening any more stands as even with only 9 flights a day to each stand (90% small/med) a/c are getting tangled at dep runways and causing a backlog and bringing airport to a halt Ignore security area, its an idea I'm trying.
