As a first officer it may be possible, but you will never see a captain seat in MSP. As was said earlier the MSP200 base is closing next summer and that will cause MSP900 to become more senior meaning even guys holding MSP right now are going to go elsewhere by next summer. The questions for FO movement are; will MSP900 remain as currently staffed, how many current FO's hold Delta CJO's, how many current FO's are willing to commute to upgrade, how many pilots already working here want MSP? Answers to those questions will tell you how long until a new hire can get there. I am guessing it will be a long time for a new hire today to get to MSP if they ever get there. Lots of speculation that the MSP900 base won't be around too much longer either, though for now the company is saying it will remain.
