Interestingly, I was going to make a post about how my JFK/LAX F service is almost always miles ahead of the F-class service (food, people, etc.) on AA193 (LAX/HKG) regardless of which JFK/LAX flight I take. Happened again yesterday (landed in HKG this morning) -- AA35 was phenomenal (people, food, etc.) and AA193 was not great (though the Purser was excellent, the remaining staff seemed grumpy, as usual).
