I am sorry but ALL those Airlines in Thailand or any where else, who can not afford to pay the employees salary should be closed down
If they can NOT pay the salary, they d ont pay landing fees, spare parts, ect ect
They become very dangerous airlines
If you accept to fly without salary for 1 week, 1 month, or more you are playing the game of the crooks who own and run those kind of Airlines
Yes Airlines industrie changed a lot (I am flying since 40 years) BUT it is not a reason to become an aviation prostitute and accept anything because, at the end you will make it even worse
