Having sampled seat 3A on BA's 788s twice last September it's safe to say that I for one will not be witnessing your undoubted standards of cleanliness anytime soon.

If (based on this forum's recommendations) seat 3A is one of the best seats on the aircraft I hate to imagine what the worst seat is like. Window seat and direct aisle access (albeit a bit of a tight squeeze) notwithstanding I was singularly unimpressed with seat 3A in particular (it felt as if I was lying in a coffin) and BA's 788 CW cabin in general (although I used to like BA's 744 UD cabin). By comparison QR's 788 J cabin is far, far superior - and a lot cleaner!
