25% is about my ratio as well[/QUOTE]
We usually opt for BA across the Atlantic but recently did AA both ways. I was prepared for the worst, but both crews - gentlemen - were excellent. Not as good as Cathay at their normal (although we once had a Cathay crew in the front, into LAX, that was probably a touch worse.) So it's YMMV.

What probably doesn't vary from flight to flight is the "stuff" that management gives the crew to work with. AA has clearly designed their "stuff" to satisfy the most discriminating free-upgrade passenger. They get no revenue, so spare every expense.
