Even different lines in the same security area can have different rules. If you travel a lot you start to recognize which machines require laptops out of bags and which don't, for instance.

It is really anxiety inducing overall though. Not to mention the ritual of getting partly undressed before the stupid thing then trying to put everything back on and in pockets on the other side.

Does anyone happen to know which ones are fine with 2 laptops per bag and which ones aren't?
