Two thoughts there (although rather off-topic, I'm afraid)
if the FAs do those sort of hours how can they be expected to look after the pax especially in any emergency condition?
if they do get 18 hours break they surely deserve every minute: and it probably is still insufficient from what I remember from my human factors course.
But,if the anecdotal evidence is to be believed, there does seem to be something odd about the 777. Does anyone know of an objective, scientific and foolproof method of determining gas levels in the atmosphere and also have there been any studies into how the level affect performance ?
