As much as I would LOVE to fly business class, it's just impossible for us. We make a yearly trip from LHR to BNE, it's a fair old journey, so I would definitely be willing to pay a couple of hundred quid per seat for more comfort/legroom. A 22/23 hour flight is not fun in Y, but I have to say last year we were on Singapore's A380 for the LHR - SIN leg and it was definitely more comfortable that the 747's. Still, 2 or 3 more inches for a £100 would be a no brainer for me.
