Royal Air Maroc has deferred delivery of its Boeing 787s until at least the end of 2014.
The Moroccan carrier placed its order in 2005 and was originally due to be one of the first recipients of the aircraft.
A spokesperson for the airline told Flightglobal that the postponement was due to a reconfiguration of Boeing's delivery schedule, and that Royal Air Maroc would now be receiving aircraft with better specifications.
He says the upgraded units are due for delivery at the end of 2014 "at the earliest". The airline has four General Electric GEnx-powered 787-8s on order, plus one additional aircraft on option.
In April 2010, Royal Air Maroc's first 787 was observed leaving a paint hangar having been decorated with the airline's livery. The airframe has also been seen in storage engineless at Boeing's Everett production plant.
Boeing has not responded to questions over what its intentions are for the original Moroccan aircraft.
