We also just had a pleasant experience. I was concerned before hand because our second leg, out of ORD, had just one flight per day. We were flying basic economy. And, I am absolutely no one as far as AA is concerned.
We were separated on 3 out of four legs, but knew that would happen and didn't care. The flight attendants were nice and one even took the time to speak with all the passengers by name. The flights were all late, of course, but didn't affect anything for us. The only thing close to a glitch was trouble attaching the gangway at ORD. Several people with tight connections on the already late flight were pretty upset. I lost my extra time to get a slice in ORD, but other than that easily made our connection. Our luggage arrived each time pretty fast and undamaged.
Now I am thinking how sad it is that I am grateful AA did its job. I should be able to safely assume a company will deliver on their end every time.
