Cool TR! So many familiar sights there...the local DC things I see every day, the retro AA neon eagle hanging out in BOS, the DFW-ANC mileage run leg that I did back in September, with the same view, the same menu, and possibly the same plane.

Very lucky of you to snag the 763 DFW-LAX. I had the reverse route which was scheduled on a 763 with NGBC seats right up until a couple days before. Swapped to 757, which went mechanical and ended up getting me into DFW late enough to strand me overnight.

Because you mention the boarding music, what is the current AA boarding song? It's literally been the same song every time I've boarded for the last couple months - some sort of country/folk thing that sounds like it's from 30 years ago. I tried googling what I thought to be a snippet of the lyrics and got nothing. FT threads on AA boarding music that I found didn't seem to make any mention of it. The deplaning music is still the piano pop you mention.
