I'm fortunate to have racked up some miles with American.
The ticket and gate agents are always polite and friendly at cle hopkins - nice :)
Flying with them, t's mostly a good experience, on a good day, hopefully getting lucky and sitting next to someone under 200 lbs, prefferably a woman .... always nice again (they tend to share the arm rest and not sit on you.)
Maybe getting the occasional bump up to first class .... ahhh.
I prefer to fly with them over most other airlines.
Other than that, flying is ... what it is.
Thumbs up AA!
