MSP at this moment is the most senior base for FOs. The base is defenetly shrinking. If you are a newhire it's going to be easier to get ATL than MSP. In the last few vacancies no FOs got MSP at all. The last vacancy awarded was for may and no FOs went there. Also there's a list of bids for MSP already so as a newhire could take a while. I would say less than a year but not less than 6 months. If you really want MSP you stand better chances going to Mesaba.
