Started flying AA in the spring exclusively DEN-MIA RT every week. I've really enjoyed AA over my UA experience....the thing is AA just changed flight schedules to 1 per day at a very inconvenient business traveller time. No one else serves this route and my client is just 10 min from MIA. I hope this schedule change is temporary. Changing plans in DFW or ORD will definitely suck compared to the nonstops.
