I know many folks that commute. I currently commute from SLC to ORD as a Captain on the RJ, i am about 2/3 of the way down the seniority list and have managed to hold 4 day trips with weekends off. I catch an afternoon flight from SLC to ORD monday, start flying early tuesday morning and then fly home friday evening after my trip ends.. Lots of us do it, but it isn't my first choice.. living in domicile makes for much better quality of life.
