One has to keep in mind the WS/UOA situation in Thailand is being politically driven, with the Thai pilot union doing what they do best, whine about everything to the government. If they're not careful, they're going to cut off their noses to spite their faces. How long do you think it would take PTT to react if and/or when flights weren't able to launch due to lack of qualified crew?
It is going to be very interesting to see how this one plays out.
