Flying LAX-JFK Transcon in J and on upgrade list for F. Last time I departed LAX in F to LHR on AA I used the Quantas F lounge since FFD was closed. I know I will have access to the Flagship AA lounge on my business ticket but will I also have access to the Oneworld business lounge or any others if I want to check those out on a Transcon flight? Also if my ticket is upgraded to F or if I take the cash upgrade offer, would I have access to any of the F lounges like Quantas?
