Even though you will lose your ability to pick your schedule you will enjoy being at work a lot more. When compared to a Regional, at AA you will be working less legs a day and have longer overnights in better cities and hotels (for the most part). For planning purposes you won't see second year pay until your 15th or 16th month after hire date. There are some weird non-industry standard stuff here at AA but not enough to turn it down over a Regional.
