The seats are assigned. People have been standing in line for 15 minutes now. Why on earth would anyone want to stand there, when they could just sit and wait until the line clears?
I understand wanting to get off a plane ASAP, but boarding? You just end up sitting on the plane, waiting for everyone else to get on.
I guess part of my different perspective is that 99% of my flight travels are for work, and I’m paid by the hour, even on days when I’m doing nothing but traveling.
