nope, but being first on a DME bus, no matter if the entire plane gets on it or not allows you first pick of the seat and since there's only one way off the bus, it's in your best interest to be in the first seat. especially when each family getting off in front of you can easily add 10 minutes to your check-in wait time.
and every person ahead of you in a taxi stand, which is combined not just from your own flight, but everyone else who happens to be leaving the airport at that moment can add a few minutes, even moreso during inclimate weather when finding a cab anywhere is exponentially harder.
at least from a new yorker's perspective.
now would i rather spend that extra 15 minutes on an airplane or in my room/apartment? well, call me crazy, but although i know i'm not going to die being on a plane for a few minutes longer, i'd rather be in my room/apt. unfortunately, too many people agree with my thinking, so that's why it's as competitive as it is. if everyone craved the back of the plane for whatever reason, i'd be happier.
fact is, until this inane ban on liquids, i was quite capable of not having to check any luggage.
now, as i alluded to earlier, if i had to go to baggage claim, it would be pointless where i sat and how long it took me to get off the plane, although again, most people are going to crowd the front of the belt and i have been virtually shut out by being the near-last to get there as well.
