It's cyclical with what happened 2 years ago. Guys (many, not all for sure) tend to bid out of the 190 right seat when they can, so the 190 new hire vacancies are driven by what was assigned in class 2 years prior to the system bid quarter. The bus vacancies are driven by deliveries are an essentially continuous stream. The driver for the vacancies that make it down to the new hire level is whether there are guys coming off of the 190 to fill those bus slots.

Early 2015 was a lot of bus hiring, so not too many 190 FO's eligible to bid off right now. Late 2015 and early 2016 was a lot of 190 hiring, so I expect this will swing back over to lots of 190 vacancies for new hires by late 2017..
