Emirates Airline is a "frustrated entity" because of a lack of planes, the carrier's president said on Wednesday, adding that it would now have an 85-strong fleet of Boeing 777-9X jets if the planemaker had been able to deliver them on time.

Emirates President Tim Clark said he’s keeping a close eye on Boeing Co. after the US company consistently missed delivery targets with its aircraft, suggesting one of the manufacturer’s biggest customers is running out of patience.
