This problem is caused by the airlines.

It is nice that many of you would let the person go in front as I did when asked. My getting out of line delayed me, someone going to the front delays everyone in that line. If the airline moves some people to the front, that is one thing. When someone near the front lets someone in line, they make a decision for a lot of people behind them that might also have a time problem or have one created for them.

If you want to get an idea of what people in general really feel then I provide the following example that we have all seen.

Plane lands very late. It lands into a major hub. People are asked to remain in their seats and allow only those few passengers that are in major jeopardy of missing their connection to get off first. This seems to accelerate the number of people that get out of their seats before the "fasten seat belt light" goes off and almost everyone crowds the aisle and the poor people that had 60 minutes to make connections, find that the 10 minutes left quickly disappears as the slow progression of "everyone" getting off first blocks those truly in need. That is when there is no question that some have an issue and yet the majority of people just push and shove anyway.

Generalization:

"Everyone" is in a hurry, that is why we fly.

Back to the airlines. They know in advance how many passengers are coming, about when and with how much luggage. The lines could "alway" not exceed 15 minutes if they really wanted to make them so. As for the late plane, perhaps more ontime flights would be a goal they could try.
