EK (to my knowledge - apart from the ex-SIA A340s) hasn't taken on other airlines' "hand me downs" and I don't think they'll do so now. I think they'll probably go with A340-600s and no doubt Airbus will make this very sweet for them (not much of a choice).
Does anyone see Airbus having a dog's chance selling the A350 to EK now (particularly with rumours that the 350 itself might be scrapped!) What is the status of this requirement; should we expect to see the 787-10 launch before year end? Think of the deal Boeing would give EK to launch the 747-8I and the 787-10 simultaneously!
