Looks like only new hires will staff the right seat of the 175.
They are going to enforce the contract where it says "FOs can't cross bid to equal paying equipment."
Life will be pretty sweet for the first couple classes of new hires in the 175. Won't ever have to experience anything like reserve, and you'll be top in base from day #1.
Not that I would ever recommend someone to forgo seniority because they want to wait for a 175 class.
