My guess would be that things are probably going to be working pretty well and many of the problems will be user error. People are going to show up and not have completed their ED card online which will prevent them from using the kiosk. But, they will park themselves in front of that same kiosk as they then try to fill out the digital ED on their phone, preventing someone else from going through. And, no doubt, they will bitch and moan the whole time, while they themselves are the problem.
There are 3 luggage carousel plus one for oversized items. The space looks quite large. I'm excited.
