On a recent op up to F I ate in the Concorde room in JFK.

Then I ate again on the flight.

Then I had a great sleep. I have been an AA junkie for 15 years but in terms of longhaul experience the two aren't even close. On BA even in J get a window seat where the egress is easy (rows 14, 20, 62, or 64 on the 747s) and you could be on a private plane.
