Over business on BA, very much so for me
Having just done an F sector it highlighted again to me how much the service levels and cabin ambience and space are so much better
I'm actually quite dreading the CW flight back, although as with Paul4040's comments above it is a night flight back from BOS and the difference is hard to justify over eating in the lounge and just getting your head down ASAP, which is the highlight of the CW service for me
