Boeing 787 launch customer All Nippon Airways confirms that the late delivery of its third 787 is delaying its plans to introduce the aircraft on scheduled international service.

ANA’s third 787 is to be its first in international long-haul configuration, and the carrier has been waiting for this aircraft to arrive so it can begin putting the 787 on selected international routes. The third aircraft was due in November, but is now expected to arrive in late December.

“We regret that our 787s will not be delivered as scheduled and agreed with Boeing, requiring us to adjust our flight schedules,” an ANA spokeswoman says. “We have told Boeing it is important that the aircraft are delivered as early and as close to the original schedule as possible.”

ANA had previously wanted to start using the 787 occasionally on its Tokyo Haneda-Beijing route during December. Now, it expects the aircraft to be used on this route during January. The revised dates for 787 flights on this route are Jan. 14, 17 and 18.

The Haneda-Frankfurt flight that is intended to be the first new route for the 787 will still launch on Jan. 21 as planned. However, it will be operated with a combination of 777-200ERs and 787s at least through the end of February. Due to the delivery delays, ANA has been forced to postpone the date when 787s take over all the daily Frankfurt flights. It now hopes to begin daily 787 service in March, the airline spokeswoman says, although this will be confirmed after the delivery schedule is fixed.

ANA’s rival Japan Airlines has also recently revealed that its 787 deliveries are being delayed again. The carrier was expecting its first 787 this month, but now anticipates it will arrive in February.
