why would you stand in queue for 20 minutes? I never understood it, I am usually one of the last people boarding the plane, heck I will be sitting there in small space for many hours usually so where is the rush to be there first if I have guaranteed booked seat with alloted space for my hand baggage, so where is the rush? never understood people standing in line immediately when they start boarding as if sitting in plane would be more pleasant than sitting in boarding area

I would understand this only in first come first serve airlines without assigned seats, but I think nobody is doing this in Europe anymore, in US you stil do this?
