I'll define a commutable trip as one with a mid-morning or later sign-in and a completion before the last flight of the night out...

There are early morning departures from most (if not all) pilot domiciles. Those trips need to be covered...

I live in base and don't particularly enjoy 0-dark-thirty sign-ins. If my seniority allows me to hold trips with more gentlemanly sign-ins (AKA: commuter friendly) I will bid them if I want to. (I suspect many pilots who live in base will do so as well.)

I'm not out to screw someone, but sign-in time is one of the parameters I evaluate when I look at bidding. I'm not going to bid "crappy" trips so the more junior commuters have an easier commute.

If a commuting pilot don't have the seniority to hold commutable trips, perhaps they should consider bidding a category that allows them that ability.
