Can someone explain to me why, when a person arrives at LAX two hours prior to departure, she makes it to her gate with maybe fifteen minutes to spare before boarding? Because at one point it seemed logical that passengers should arrive well in advance of their departure time. It was important to ensure that airport security had adequate time to fully screen everyone and weed out terrorists, even the ill-prepared ones who scheme of taking over planes with deadly tweezers.
But why are we waiting in lines that wrap around the outside of the airport and continue for about a block or more (this is LAX) when we're not any more secure? Because given the choice of sleeping in or waiting in an hour and a half line, I'd choose the former. But maybe that's just me.
