FlyingDoc: This is exactly what I was driven at in my previous postings. A true First Class service MUST be consistent. Like top grade restaurants. While BA FC service can be exceptional some of the times but is more a question of luck as often you would find yourself travelling with FA with a BIG attutide. A “BA Roulette”.
If you want to have top flight services and for your route then you should stick to SQ and CX as they never disappoint. There are also other good ones around. I am not pro any airlines but just knowing what is the best in the sky!
