How many first officers are there for the CR7? By the time I start in January, the 175 will be offered up again, but commuting from GRR seems like it would be better off to select an older plane with first officers who are upgrading off of it, and an easier commute with 14 flights to ORD and 3 to MDW per day, as opposed to a newer plane that won't have upgrades coming for at least two more years and only 3 flights to DFW. Am I wrong in thinking that the CR7 is a better option? Shiny new jets are nice, but QOL on the CR7 seems like it would be better.
