Jetsbest,
Blimey!!!, everything old is new again.
"Back in the day", a typical PanAm roster for some ( you needed to be senior) crew was one round the world trip per month, either east or west ---- no long sectors, but plenty of long ToD, you started off east or west, and kept going.
Typically a two week trip, that accumulated the monthly pay hours in one go, rest of the month off.
Tootle pip!!
