Inside word on Emirates fleet planning is that the A345's WILL go. The problem is that with all this expansion, EK needs every hull they can lay their hands on. So they will be here for a while.
The A343's are here to stay as they have proven extremely cheap to operate plus they cost next to nothing to buy. They are looking for more A343's. Ex Virgin ?
The big regret apparently with the A330 is that they didn't get A333's. The center tank on the A332 is never used. Don't be surprised to see them replaced by the T7.
Why wouldn't Branson take some of the 600's that EK is now thinking of "deferring" ? Good way to start his OZ operation.
