Commuting isn't so bad when flights are open and on-time. A 1-2 hour flight isn't so much the big deal. It's the constant unknown that gets to you.

When there's a question of if you're gonna make it on a flight, it's an added mental and emotional burden. You don't know if you're gonna be sleeping that night at home, in a crash pad, or crew room chair. If you're doing this every week, it gets old.

If you find a commute that is consistently wide open with little competition, then it can almost be enjoyable. This happens with slow seasons on city pairs, but if the flights aren't full, they'll reduce the number of flights eventually.
