As a line holder, I would drive up to 3 hours to avoid a plane ride. Beyond that and it starts to make sense to commute provided it’s one leg and simple. If it’s more than one leg, or few viable options I’d even consider driving 4. Buy a hybrid something or other that gets 50+mpg and hopefully do it no more than 3/4 times a month.

I used to commute on a 45 minute flight where there were 20 options per day vs a 4 hour drive. I still drove it during the holidays to guarantee I got home. While it would have gotten very old, it was always a great relief knowing when I landed I was going to hop in my car and drive.
