Last time I flew LHR-JFL, it was in 3A on a 77W, and very nice it was too. However, for an upcoming JFK-LHR flight, it seems AA are now using the 772 on this route. From what I've been able to find out, these are still full flat beds but in a forward/backwards configuration rather than herringbone? Am I correct , and are they still OK for an overnight flight? Before I push the button....
