Many years since I left QF but....do they really employ 18 year olds as cabin crew?
Surely not International Crew - the drinking age in some ports is 21
Seriously though, on a recent trip back from HNL I asked the Jet * attendant how many days off they got there, where they stayed these days, etc - just small talk as she was a nice girl and pretty attentive. Anyway, she said they had 2 days off and the night after they arrived back in SYD, she was off to DPS.
Now, I had a good nights sleep, went to work the next day and crased about 10:30 the following night - this girl would have been 5 hours into her SYD-DPS sector BUT she then has to turn around and come back to SYD, surely that is not healthy and more importantly that should raise some concerns?
