My scuttle butt is in line with Keg's. The delivery schedule is for 3 B787-9's in late 2107 with 5+ deliveries in 2018. I've heard that recruitment will start mid 2016, mainly due to the shortages on the B747 & A330 fleets & these shortages won't be fully filled by those returning from LWOP.
The recruiting figure is 200+ but I don't know how long that figure is spread over.
