When I was in Jet, it was legal for two pilots to do up to 10 hours of flight time, if at the planning stage it looked like 10 hours might be exceeded an extra crew member was called out…however I must say those early A.M. departures out of BOM/DEL for LHR/BRU were very tiring, it was not unusual for the other crew member (local) to order blankets and pillows from the cabin crew and curl up in their seat and sleep for several hours, leaving their equally fatigued colleague to press on single pilot….
