Can’t believe this actually needs explaining… but a ship moving at 14kts covers
ONE timezone in 74hrs at the equator (1035 miles). In 74hrs a LH airline pilot has been 7 timezones East, rested for 24hrs, flown 7 timezones west and is now 26hrs into 72hrs of rest at home before flying 8hrs West. Until you’ve experienced that 5 times in a month then your opinion on the subject adds little value.
It could be a gimmick for Virgin pilots to be saying that they’re fatigued so need a 35% payrise to make it safer, but in this case everything that’s being asked for is about getting more sleep - either on the aircraft, downroute or at home. Things you might be grateful the pilots have had when you’re in the back of the aluminium/composite tube
