I found the service of AF terrible....I have only flown them once and it was a relativley short segment LHR-CDG it was rude almost to the point of AR/IB standard ....but when compared to BA they really fall down...I find the service on BA to be some of the best I have had....while obviously the Asian carriers are still a notch up on BA service...sometime Cx/SQ can be a little stiff in the delivery....which is where I like BA they are genuinely friendly in their delivery.....there food isnt that great though...
