What they are saying is that if you are an 8 s/o you better bid for the open ANC slots now, or you may never make it back up front. They may be parking some eight's but they are not displacing off of it. So, get your capt. slots now old timers on the eight, because it may be a while before any vacancies come available.
I may add that nobody knows what is going to happen in a displacement. Too many variables to look at to guess what is going to happen. All I can say is that UPS has just made life and quality of life more difficult for I would guess 2/3 of the pilots. The next few years around here are not going to fun.
