Good luck holding EWR as a new hire. The last bid shrunk EWR by 15%. Good news is we are opening IAD and it is junior. The only saving grace to being a new hire is if there arent any bid's going on(which could fill the base with more senior people) and the company needs a few guys in EWR for whatever reason, they will put new hires into the base while more senior people are stuck in their base until a bid comes up or they are able to trade. So you MAY luck out and get EWR, but I wouldnt count on it. I would bet that you would be able to get IAD.
2 hour call out. Start times depend on base, but usually have 3am, 6am, 9am. There are noon and even 6pm call out times, but I havent seen them in the bid pack in a long time. 10% of the reserve lines are 12 hour call out so usually not to many 12 hour call lines. Holding a relief line could be quick, could not be, depends if movement continues, which I think it will.
