If you go by the bottom 4 pilots on the list...ONT is the most junior, followed by SDF. Looking at everyone hired June-August this year, the overwhelming majority of newhires went SDF 757/A300/MD11 or SDFZ (Z is 757 International).
Contract 2016 has a new provision by which 2017 newhires will be able to bid for available vacancies (domicile and fleet), which will be awarded in seniority order.
The company contractually must publish a bid containing vacancies, and any outstanding vacancies after the bid closes go to newhires. I would think such a bid would come out sometime in the next 3-4 weeks...and what eventually is available for newhires depends on what vacancies the company publishes and how they get filled internally.
I would suspect SDF/SDFZ to be fairly available (it is the biggest domicile by far), then ONT, MIA less so, and ANC is senior.
