Ta! Got back this morning, as it happens. Can't say we saw any of those problems on our flight. Then again, the prices BA were after for holidays with flights to Barbados may well have had an effect in putting people off.
Rather nicely, we had a spare seat alongside us both ways! One either side on the way back. So, rather luckily, for her first flights, Little Miss CFH had her own Club sleeper seat! She slept solidly almost the whole flight home overnight.
Only two empty seats in the whole of Club on our flight back, Sadly no First on the Antigua sector, otherwise we'd have been in there.
No idea about what was going on out the back in those odd little seats.
