Also, the continual jet-lag is very tiring.My experiences with vs were predominantly great and professional pilots/crews doing their best .A JFK was virtually a short haul flight but even that comprised a night flight home and a couple of days to recover. It is hard to convince outsiders that the perceived glamour is actually continual fatigue,room service and attempting to recover between flights.It cannot be realistically compared to an office job -like most pilot jobs in fact -but the time zone changes take it all to a new level.Good luck to the chaps/esses.
