"We" all don't love commutability, I'd love to have something like your propose. It's pretty easy to stay just AM or just PM, even if you are forced to fly bid packet trips. What you're talking about is a big reason I prefer to clear my schedule and fly turns. Wake up in my own bed, fly a turn that TAFB is usually less than 6 hours and make it home in time to make dinner. Even if I fly afternoon trips, I'm usually home well before I'd normally go to bed, so I'm staying on my normal wake/sleep cycle. While we have some early getups, I generally feel better by not flying redeyes, staying within one time zone and staying on am flying (I had 30 hours due to the body clock swap). Another big benefit of this is bringing my own food, which is much better than crap found on the road. All of these things are probably a big reason I don't regularly use 100+ hours of sick/year.
