After looking at the All Things 787 charts there are listed 92 of Boeing's 787's for delivery during June - December of this year. After five plus months of delivery processing 53 of the 787 were delivered at a 10.6 a month pace. Currently there are 57 delivered through June 10, 2017. The charts also indicate ninety-two 787's should be completing the process by year's end from June 1. This will indicate a total of 145, 787 for the year (53+92= 145). Whether or not that quantity are received by its customers is a strict guess. This depends on the customers urgency, financial ability, and changing market conditions which could all contribute towards a delay on any delivery.
Boeing is positioned to meet guidance for about 138 units delivered during 2017 and it is feasible it could go long and reach beyond 140 of this type delivered during this year. Another observation is Boeing has blown by the Airbus A-350 backlog margin and continues to take orders in a wide body down year. The air shows are yet to come and it will be interesting to see everything shakes out during the Paris Air Show. Backlog is a function of Orders and Deliveries. Boeing having a lower 787 backlog while it has a strong production outflow gives Boeing opportunity to sell more 787 for relevant delivery in a corporation's timeline. However, taking more wide body orders over its competitor also increases financial strength which will reduce its 27 billion deferred cost money pit.
If Boeing processes 92 from June 1- December 31 1017, it will maintain a build to completion pace of 13 of its 787 a month. This will be a increasing pace as the 787-10 matriculates itself into the production process.
