Well, I think Emirates has firmly brushed aside the myth that MAN has low premium demand.
Hot on the heels that they will increase the morning flight to a B77W from A332, they have now confirmed via the booking engine that all 3 flights will now carry F class as of 1/9/12.
Seems its really paying off otherwise there would be no incentive to swap the HD 2 class version off the EK19/20 to a 3 class one.
