They're all American Airlines aircraft now, does that email mean LAA side? I'm guessing you live in an LAA domicile. For those that are worried about being based on the wrong side of where they live, take the long view. You'll likely be able to switch between the two (three really) sides in a year or so. It's not the end of the world to commute for a few years. I'll probably be commuting for the rest of my career, BFD.
