Steve,
Going back to what Poto wrote on page 1 of this thread:
So the Thai cabin receive $258/month plus$7hr per flight hour. And BB tells the ABC that they earn up to $30k per annum without busting the, load of crap, FRMS that the QF group have been forced to embrace.
That means they fly 74hrs a week with no annual leave
Poto's calculations are correct.
That means that, assuming they are given 2 days per week off, they are working 15 hours a day, every day. That is the equivalent of Sydney to Los Angeles (or back), every working day.
If you throw them 4 weeks off a year, then the calcs show that they are working 80 hours per week over the 48 working weeks. That is 16 hours every working day.
That is when errors occur.
