We have a few guys in my base with such a lengthy commute. They quite often end up in hotels after delays, or when rostered with minimum rest between flights. I guess it will all depend on your roster, personal circumstances and sensibility. You’ll probably need a hotel for your standby duties.
I did weekly 2.5 hour commutes for years. I did kind of enjoy the drive (podcasts, audiobooks etc). A daily 3 hour drive, that’s a lot of precious time though!
