No first hand experience but I knew a few panhandlers who commuted, mainly to IAH. Seemed like it was pretty easy for them, I even knew a guy who would commute in day of, sit the midday airport reserve in IAH, then commute back home at night. Never really heard anybody complaining about it being a difficult commute to IAH. A different guy from JAX stayed in IAD because the commute was easier. All the South Florida pilots seemed to prefer IAH as the easier commute.

What I will add is that CommuteAir tends to break the conventional wisdom that it's always easier to commute on one's own metal. If you live in a larger city, its a moot point because CommuteAir doesn't fly there, so you'll always be on mainline or maybe Republic/Mesa. If you're in a PNS/GPT/MOB/ECP, then there probably aren't a TON of pilots commuting anyway so the 737 or 175 that comes in will almost always have an open jumpseat, but when CommuteAir's 145 comes over, they are relatively frequently weight restricted so you might get kicked off regardless of whom you work for. Anyway, just my 2 cents from doing the IAD commute out of a small city in the Northeast; never had a problem with getting a jumpseat down on Mesa, Republic, or mainline, but have been weight restricted off the 50 seaters at least once or twice.
