UPDATE: It appears that ZA104 will not be going anywhere due to ongoing tech issues. This aircraft did fly today and will also fly tomorrow. There should be more clarification on its status later this week. Currently both this aircraft and ZA102 are scheduled for delivery in January but I do expect at least one more 787 to be delivered this month. Currently NH9397 has left on its delivery flight to Tokyo.
According to Flightaware, NH9397 (also known as ZA116, JA805A, L/N 31) will flying out to Japan on its delivery flight at 6 pm Pacific Time. According to sources this aircraft should be parked at gate 206 when it arrive at Haneda International Airport tomorrow morning.
The same sources said that NH9399 (also known as ZA104, JA807A, L/N 41) is scheduled to leave Everett at 7:15PM Pacific time and will be parked at gate 205 when it arrives at Haneda. ZA104 took an earlier flight around the Washington State area supposedly by ANA pilots so it is unknown if this plane has actually been delivered.
These two airplanes are fitted with the Trent 1000 package "B" engines which brings fuel consumption to within 1% of promised specifications. These airplanes will be employed on ANA's international routes beginning with Tokyo-Beijing later this month followed by Tokyo-Frankfurt next month.
