Pretty much any regional is going to have a wide variety of lines, some more commutable than others, so the company is not really a factor. More important is...

- Where you're based.
- Where you live.
- How many non-stop daily flights on company or codeshare airplanes.
- How many non-stops on other airlines.
- How many pilots live in your town and commute to your domicile?

Only one airline comes to mind as being unusual ....eagle used to be VERY commuter non-friendly...they either forced new-hires to live in San Juan, PR or even if you didn't get that good deal you would have NO travel or jumpseat bennies for your first six months. This was years ago and hopefully has changed now that they are short on pilots.
