When I typed in each of the regs of each of the six AA
77Ws on Flightaware, I saw that N722AN, which had its maiden flight just over a month ago, is scheduled to operate the flight. If you're going to be on the flight, congrats and have a good one!
Btw, as I'm writing this, the flight is scheduled to depart in 15 minutes, so the thread may have lost its importance by now.
