Allowances...
oh, and if you add their allowances to the equation you will see why they are actually wealthy people within Thailand!!!
They have to have a degree before they are excepted, and those that go to uni in Thailand usually come from a well off family!!!
Take a look at where the thai crew fly...
LHR, FRA, SIN, NRT, HKG, SYD,PER, BNE, MEL, AKL. Then take a look at the allowances paid daily in these ports and youll see they are far away from living in the poverty column of Thailand.
