I do quite a lot of short haul flying in CE/business class/F (BA/LH/LX/JL/NH/CX and even did 4 sectors on AA domestic F last year which was the first experience for me). CE is generally OK on BA and some are fantastic, but there are fair few flights that if I considered them a treat I would be disappointed due to perfunctory service. I don't personally really care much as my main purpose in flight is to sleep a lot, but many people consider business class/CE to be a treat so they probably should put some extra efforts in.

In fact, the failure rate on standard services on a 767 is very high. Nuts missing, menus missing, doing service in a strange way etc is very frequent. Those things do not necessarily make the flights bad but they are a bit 'weak' and mediocre. It doesn't tend to happen as much on A320 family. There must be something about the 767 that make the crew a bit disorganised I think??

I don't tend to have much problem on long haul as they are mostly in F. There were occasional slip-ups like being completely overlooked in CW once last year (I was in a cubbyhole seat, admittedly) and some slack CSDs but by and large they are fine.

I'd say, in terms of the on-board services, at my current guess 10% of BA flights are really excellent and outstanding. 60% of BA flights are good to very good. 20% are OK to a bit better than OK. 5% are mediocre and could do much better. 5% leave quite a bit to be desired.

It leaves BA at a high percentage of "good to excellent" and I have to admit I like flying with them.

There are just some really poor crew around that give BA a bad name, unfortunately, because bad services tend to stick in people's mind more.
