There is not a 3-yr seat lock at Mesaba. New Hires will be under a 3-yr EQUIPMENT lock UNLESS they can hold an upgrade sooner than that. What it means is you cannot be hired into the saab as an FO and in 1 year lateral over to the CRJ as an FO. You CAN upgrade at the first opportunity, even within the 3 year period.

Our upgrade minimums currently require 1000 hours of Mesaba flight time or 2 years with the company whichever comes first. There is no total time requirement other than FAR ATP mins.
