I have been flying pretty regularly for four years, almost all on AA, almost all PHL-LAS and back, some connections, mostly nonstops. What I can say that's good is that in approximately 35 trips, I don't think I've had a major meltdown. I've had luggage lost and badly damaged and a couple missed connections, but I always got where I was going at worst within a few hours of when I expected to and in the class of service I paid for (or higher).
In any other industry that would be "damning with faint praise" but in the airline biz it's almost Gold Medal time!
