Hi all, on a ticket to Europe I have the option between booking the transatlantic segment on BA First thru JFK, or AA Flagship First thru Dallas or Miami. I was fortunate enough to try the Flagship First dining room at JFK before it closed, and it was one of my best lounge meals ever! Anecdotal reports out of the Chelsea lounge haven't looked as positive as my Flagship First dining experience. However, the Dallas Flagship First dining facility in particular also seems to get poor marks...

Which of the three would y'all pick, all else being equal?
