Welcome to FT strawdan, and what a great question to open with!

Some very interesting information above, I love the deep clean idea and it's a shame it doesn't work for them. I wonder what else BA could do to 'monetise' aircraft that have long layovers- I'm sure I heard of some sort of aeroplane restaurant somewhere in Africa! Or maybe it could be used as a filming location...? Sounds like a great project for one of those graduate trainee management types.....
