Great report!

Not sure how I missed this when first posted but this is a very good one to see, as this route might have significant utility to me personally for future trips. BOS is one of the few international gateways that I can count on regularly finding AA award space to (it's often harder for me to find award space from DCA to JFK or ORD than it is to find TATL/TPAC partner space in a premium cabin). And, with the upcoming AA devaluation I'll probably be flying J more than F.

I know that a lot of people complain about the angle-flats but I don't sleep on flights so that doesn't really matter to me. More importantly, looks like this flight gets the usual great JAL service and catering. And maybe one day they will put different equipment on the route anyhow (I forget for which routes that is in the works).
