Hello all, I’m OWS with BA and flying JFK-MIA on a redemption in First (ticketed in U class), on the AA2219 in mid December. I find lounge access rules a little confusing since the new arrangements started but can anyone advise what lounge, or lounges, I can access please ?

FWIW, I’ve also an Amex Platinum so have Priority Pass etc too.

Thanks in advance.
