I tried just changing my manned desks 1:1 to automated check-in desks. Unfortunately, in its current state, I just don’t see it working. Basically, if I have two or three bag drops (and multiple self check in kiosks), my flights still end up all using the same bag drop and abandoning the other, so a crowd forms around the only in-use bag drop (also doesn’t help that you can’t build a queue for those).
There are actually similar issues for things that are built in multiple–for example, one flight may be assigned multiple check in desks, but they’re not necessarily the ones next to each other; sometimes all my flights crowd into the same baggage claim area, and leave the other one empty; my passengers seem to all like to use the same bus stop (that has very infrequent service), rather than the multiple other bus stops (with queues of buses, but no passengers!)… etc. But I guess things can’t be perfect!
