Sfo is possible, 175 best choice there, crj it's a senior base for a lot of the seniority list, especially since bro ppl were based there. Msp and ord to a lesser extent is junior and stays that way because most people are just biding their time to gain seniority somewhere else. DEN on 175 for FOs will be junior at first then potentially gaining seniority, by that I mean 2-3 year FOs as 4 year FOs are upgrading in other bases.
