Emirates is the biggest customer for the Boeing 777X, and its president is not impressed with the latest delay announced by the embattled planemaker.

Emirates, the world’s largest international airline and a major buyer of Boeing Co. widebody aircraft, said it will have “serious conversations” with the US planemaker in coming months following an announcement that the 777X model will be delayed yet again.

Emirates plans to hold a "serious conversation" with Boeing in the next two months after the troubled US plane maker once again pushed back the delivery date for its 777X, delaying its largest wide-body aircraft by about six years.
