So that’s 74 aircraft with New First out of 88 aircraft with F cabins. 14 soon to be retured without being retrofitted.
That’s 84% with new F and of course the non new F is restricted to mid-J 747s, so normally routes with less business traffic (e.g. MIA).
I would imagine the non-converted birds will increasingly be used only for standby as the new A380 fleet arrives from next month onwards.
So you’re 100% getting new F on a 777.
100% getting new F if on a hi-J 747.
Chance of old F on a low-J 747 around 50%, but decreasing as the 747s start rolling out of service.
