I may be looking at this through rose colored lenses but my current considerations are the following:

Presently I commute (by car) 2 hours a day, 5 days a week. So 40hrs a month.

If I am hired by the regional that I have applied, it will be a 6 hour round trip commute by car. So, basically, I could make that drive 6 times and be in the exact same boat im in now. My understanding of a typical regional airline pilot schedule, I don't think you commute to base 6 times a month, more like 3-4 times per month.

Am I way off base here?

I commuted internationally for years and I can say it depends on your situation, seniority, schedules. My wife went back home (Europe) to help with her mom.

For 4.5 years I would go back and forth between New York and western Europe. It was the lowest stress commute I ever had. Worst part was the bus ride to and from the airport. All the flights to the States left within a 1.5 hours of each other. First class 90% of the time. Missed 3 times in 4.5 years. First day was normally a deadhead or 1 leg to the overnight.

Got onboard aircraft. Eat my breakfast. Sleep for 5 hours. Watch a movie and go to work.

10 Minute walk (bus to train also available), 20 minute train ride, 5 minute walk inside airport to KCM. 1-3 minutes to a computer to sign in or 5 minutes to crew room.

I give myself 45minutes to an hour prior to sign in. Used to drive 30 minutes than take 20-30 minute employee bus.

Curious to know if you decided to drive or fly for that commute!

Yes. After driving 3hr are you going to be fit for duty for a 12hr day? How about after a 4 day trip you get back late at night, will you be safe to drive home? Sometimes I question if my drive for an hour is safe after a long trip.
