Cheeryguy, I wasn't suggesting that the M or WT cabin be closed to provide Crew for F class! I was thinking that couldn't the crew be shuffled around to cover the F class especially as you point out we try and 'target' low F class booked flights. This may mean a poorer service down the back, but its the premium cabins where the money is made.
Ba Boi....looks like most people don't share your view of the world...
