The results of the December Advance Entitlement (AE) have been published. IAW the PWA 22.E.10, NH's can only be offered positions that were unbid by pilots already on the seniority list. As such, by my crayon math, this is my best guess for available unbid vacancies which can be offered to the early Jan Indoc class(es)*:

7ER (757/767 'classic')
- NYC: 30

73N
- ATL: 15
- LAX: 7
- NYC: 25
- SEA: 8

320
- DTW: 20
- NYC: 10
- SEA: 0
- SLC: 2

220
- NYC: 15

717
- DTW: 25

Total: 157

* When a pilot bids out of a category, it offsets one pilot who bids in. The net of the posted vacancies are available to NH's. Each new AE resets the list, so the late Jan classes can only be offered unbid positions from the Jan AE, which will close/publish around the 15/16th of Jan, give or take.
