Not like there's a cruise pilot on 737's
Some operators use a 737 three man crew on long duty sectors in the Pacific region. One real captain and two first officers of which one gets called Cruise captain to keep him happy. Wears 4 bars on his sector while the captain snoozes down the back and three bars when PNF. The union makes sure he gets paid an extra 15 grand a year. Not a bad rort if you can get away with it...
