It's already December 15th and thus far I can confirm that Boeing has delivered 5 787s thus far but I am waiting on confirmation on 3 additional deliveries to Avianca (2) and Azerbaijan Airlines (1) that are scheduled to be completed by the end of today. With the 5 deliveries in December (thus far), Boeing has delivered 101 787s in 2014 and need 9 more to achieve their guidance of 110 deliveries. They do have plenty of aircraft that appear to be ready to be handed over to customer as additional customer flights have taken place over the last few days.
the delayed deliveries of many of these aircraft have been attributable to different reasons including:
Delay seat deliveries from seat vendors (i.e. Zodiac) or delays in certifying the seats for installations Avianca, Etihad, American Air). Bloomberg has an excellent article on the delays attributable to Zodiac
Financing issues (Azerbaijan Airlines).
Despite the trouble with deliveries, Boeing has still being going full tilt on production and my season adjusted calculations show that Boeing will start work on 8 787s in December while rolling out 9 from final assembly.
Lastly, the plane spotters in Abu Dhabi will get a special treat as Etihad's 1st 787-9 ZB077 (LN 229, A6-BLA) will fly to the country today, December 15th for a marketing trip. It'll be there until the 18th and then fly back to Everett. This aircraft still has not been delivered and has yet to take a customer flight though I don't know if the flight to Abu Dhabi wold count as a customer flight. Boeing is still aiming to deliver this aircraft to Etihad on Dec. 31st.
