I assume most everyone tries to board early, except on Southwest where it would be slightly obvious if 45 people were trying to stand in an area that was for 15 passengers or whatever.

The worst I saw was that some kid was trying to get on the flight as an unaccompanied minor from PBI-BWI. The gate agent said he needed some kind of form and that he had to walk back to the counter by the gate. We thought it was terrible to suggest a kid to walk by himself in a busy gate area. As it turned out, his parents were with him and they tried to pass him off as an unaccompanied minor so he could get on board first and save seats.

Finally, plenty of people get on Southwest flights claiming they need assistance. They roll down in a wheel chair. Somehow, they're healed on the way down. I think if you need assistance getting on the flight, you should have to wait until everyone else gets off and then you must have assistance getting off the plane. That would stop that nonsense.
