You guys are talking a good amount about a "min day", but missing duty and trip rigs.
A min day
could cause the company to extend your first and last day to make sure they're not giving away 'free $', but it has no real effect on productivity for pilots, nor does it really increase QOL.
A trip rig is a useless concept for regionals - the trips are too short for the rig to kick in.
A duty rig is what regionals need, and what incentivizes your company to build more productive schedules and reduce your sit time. It allows for stand-up overnights too. The time in the hotel might get longer, but if you're going to be away from base anyway, you might as well spend more time in the hotel and less time sitting in the airport each day.
APC did a great service to 'dumb down' rigs. Go
here to check it out. Plug your schedule in and see what comes out. Remember, the goal of a rig is not to make $, but to incentivize the company to schedule you to fly while you're @ work. In an ideal world, the rig never kicks in.
