I see it come up all the time in the forum....commuting. Most people say it's two different jobs commuting v driving to work. I believe them, makes total sense.
I live in Grand Rapids, MI(GRR). It's a busy airport for it's size. It's a 50min-1hr flight to either Chicago or Detroit. How would it be commuting with that short of a flight?
Delta, SWA, and American each have 3-6 direct flights a day to their given domiciles in Chicago or Detroit.
Chicago is a 3 hour drive with no traffic or weather issues(rare). DTW is 2.5 hours with no traffic or weather issues. I've driven to both airports dozens of times and it gets old FAST. So please don't focus on driving. I live 15min from GRR.
