OK fair enough, perhaps we were speaking in the wrong terms. Do I think AA will up and disappear one day, no, not anytime soon. However that doesn't mean that they cant have serious issues that would cause them to shrink or slip from the #1 spot.

My point was that someone shouldn't base their decisions on the best case scenario which in my opinion you are arguing for. I plan on going to AA, so I certainly not trying to disparage them, I just also know that things can change and change quickly.
