Air NZ is due to take delivery in the near future of the troubled Boeing 787.
It is likely that the US Federal Aviation Authority will decline to extend ETOPS certification to this airframe.
This is a certification which allows twin engined aircraft to operate an extended range from the nearest airport. An airline which operates extended oceianic routes would need such aircraft in its fleet to operate efficiently If such a certification is not availiable I would expect this to have a material effect on Cullen Airlines earnings
