I refer to your post (#477), Dennis where you were surmising the delivery dates of the last three 789s ordered by QANTAS, particularly the 12th aircraft ZNL, which will be needed for the daily flights to Santiago:

That means that ZNL, number 12 must arrive in June 2020? I understood that the last 3 were all arriving later in 2020.

ZNL, the 12th 789 for QANTAS, in now on the Boeing 787 production spreadsheet with line number 1019. This is a further 90 deliveries from ZNJ, line number 929, which was rolled out on 1/10/19. Based on the 2018 delivery numbers of 12 787s per month it will be 7.5 months until ZNL is rolled out, which equates to mid May, 2020. Given ZNIs conservative one month from roll out to delivery date this would give a delivery date for ZNL of approximately mid June, 2020, tight but in time to operate the first flight to Santiago on 24 June, 2020.
I have no idea of the delivery dates of ZNM or ZNN until they appear on the production spreadsheet and I can do some further calculations.
I appreciate that this is an approximate calculation and numerous issues could occur that delay production of the aircraft but gives an idea of the 12th 789 delivery date. I have done very conservative estimates and the delivery could be as early as the second or even first week of June, 2020, especially if the delivery rate is higher than 12 - it looks to be more like 12.5 for the first nine months of 2019 or the roll out to delivery time is less than a month, as I have seem for some 787s.
