Looking at another site with this information (red1aviation.com, not a free site), their listing of flights by AA has a disclaimer saying they are working on correcting AA registrations. > The AA 'registrations' tend to be the fleet numbers in the format NfffAA, where fff is the fleet code. It takes one extra step, but they're available. I discovered this when I went to look up a flight that I took in November of 1998. BTS listed it as N356AA, which belonged to a now-destroyed homebuilt. AA's fin 356 belongs to N39356, which was indeed the ship I flew.
