A lot of my lines have been built by PBS in the mid-80s. I've done a bit of trading and have gotten that to anywhere from low 70s to high 90s, depending on how much I want to work. Since my trips are augmented, just under 1/3 to almost 1/2 of the flight is spent sleeping. Dozing for dollars.

Because some of the time I'm on the clock is in crew rest, I feel less tired flying a WB schedule. If you can't sleep in the bunks and/or don't easily adjust to different time zones, you're better off flying NB domestic.
