From Oct. 18 to Oct. 22 inclusive, Boeing took advantage of a break in the weather to fly 6 different production 787s on their B-1 flights. The aircraft were obviously ready but bad weather forced a hold on all B-1 flights. Thus when the break came Boeing released the planes for flight. However because of the delay, I expect that none of these airplanes will be able to be delivered by the end of the month. It does potentially set up November as a big month for deliveries but there may be a knock on efffect as 787s that were scheduled for flights around this time will be pushed back to later this month and certainly into early November.
ZA270 (LN 61, SP-LRA) - LOT Polish Airlines
ZA430 (LN 73, B-2728) - Hainan Airlines
ZA290 (LN 77, N26906) - United Airlines
ZA239 (LN 60, VT-ANK) - Air India
ZA261 (LN 44, ET-AOP) - Ethiopian Airways
ZA460 (LN 57, A7-BCA) - Qatar Airways
In addition to the increase B-1 flights, there was a very noticable increase in follow on flights of other airframes that have already flown. There included a C-1 flight for ZA238 (LN 54, VT-ANJ) which is expected to be delivered to Air India before the end of the month, hopefully).
Given the increased activity, however, I do not expect a lot of deliveries in the next 8 days. There are really 3 airplanes that are ready for delivery or will be ready for delivery. There is a possibility of one more airplane that could be delivered this month but it only has an outside chance.
Ready or almost ready for delivery:
ZA537 (LN 74, CC-BBB) - LAN
ZA264 (LN 75, ET-AOS) - Ethiopian
ZA238 (LN 54, VT-ANJ) - Air India (only had one C-1 flight may need more)
The one airframe that might make it for delivery by the end of this month is:
ZA511 (LN 63, JA816A) - ANA
The last aircraft still needs to perform customer flights and I am not sure if it has completed all the Boeing test flights at this point even though it has flown twice.
It is apparent that if Boeing can maintain an aggressive flying schedule in November, they can have a lot delivieries in that month. Much depends on the aircraft condition after completing final assembly/change incorporation as well as weather and the ability to work through the backlog of planes that are finished and need to go through testing.
