Emirates ponders resurrection of stalled Airbus widebody order
I hadn't been aware that the new airport had been pushed back; anyone know the new likely opening date?
Basically, as well as new A330-300s, the airline is also looking at changing the ratio of A350 orders, to include more of the -1000 models. (For reference, the A350-1000 is 240' long, a smidgin shorter than the 773/W, which is 242'4", although the 777 is considerably wider).
