When Scot Airways left the building I tried AF and BA but they were invariably late or cancelled, the RJ is not a comfortable seat, too squashed for a lardy like me, so I now do BA to LGW on the A-319. Punctuality is still an issue, the brekkie is not as good as SA, but at least I have a seat which caters for passengers with backsides wider than a supermodel's.
I do this trip weekly and I sorely miss SA as do a number of other regular PAX who've stopped using BA/AF.
Not surprised there's hardly anyone using them
