I prefer an aisle seat, especially on a longer (3+ hour) flight.But I've never found a flight where I boarded before the B group (I am A-list) that did not have aisle seats available. Since I usually am not trying to make a tight connection, I don't have a strong preference to sit in the airport as opposed to my seat on the plane at the destination. If I am not making a connection, then the time between being the first off and the last off is maybe 10 minutes. Not nearly long enough to let the difference ruin my day, or even part of my day. If I had to be on a plane sitting on the tarmac for more than an hour, that could possibly put me in a foul mood - but if being 10 minutes later getting off from an aisle seat toward the back rather than the front is the worst that happens to me, I feel like the flight went about as well as could be expected.
