I assume nothing has changed and that AA Codeshares booked in N class won't allow seat selection?

I do find it vaguely funny that AA claims they can't choose seats because it's on a JAL flight and on the JAL website it says clearly that they can't allow for the choosing of seats because the flight was booked as a codeshare through a partner airline. Truthfully, I'd almost pay money for just some peace of mind.

Thankfully (maybe), I am flying out to Tokyo on the 24th of December from LAX and can only hope that with the low odds of people flying on the 24th and 25th, maybe the plane won't be too full regardless...
