I beg to differ. I was on the 777 for years in IAH. Flying pilots to NRT had a 6 day with a tag, 2 bunkie trips were 25 hr 3 day. My 20+ years couldn’t hold bunkie but I did a number of 6 days.

No way in hell will the senior old WB FOs do unaugmented. Hell I knew many who gamed the system to force landing class to get bought off trips for class. More pay and more time off. They’d probably die if they didn’t have breaks and a snack tray.
