I was just wondering this morning, after noticing the bathtub in the bathroom still full of water ready to be bucketed out to the garden, do you think they'll ever have a swimming pool of sorts on long-haul international flights one day? Or, at least, perhaps a warm, bubbly spa-bath?

They do on cruise ships, but that's obviously because the ships nowadays are so darn big. Space on a plane, even for a 747 or an A380 is very limited, but I was just wondering what you think?

If something like this was to happen one day in, say 20 years, I wouldn't be surprised if Emirates would be the one to do it. Their first class suits look like they beat other airlines hands down (having said that, I've never flown in F with them)
