Ohh AA is like my little girlfriend used to be. Always changes for whatever reason. My previouse experience with AA is always there is schedule changes somewhere in the line. Last year I had about 20 AA sectors and there were about 4 Sector schedule changes.
This June I have 18 sectors booked so far I was informed in April that 6 sectors involve changes and another two flights have minor changes like 5 or 10 minutes. I have to change routing for two sector due to the change. I have to change another flight due to tight connection (from 55 mins to 25 mins) in Dallas. Have to say goodbye to one B763 Frst seat and be downgraded to the B757 one...
