Hey Gonzola
I can comment on Orient Thai.
I was recruited for their 757 as a pilot/check airman. I don't know if they still have the 757 or not. They change equipment quite often. 757s to the MD80s, 747s They are nice enough people. The pay is very low. You have to pay not only for training, but hotels as well. You have to wait for the Thai Department of Aviation to approve your certificates... and while this is going on you are still waiting in the hotel at your expense. It could be a great vacation or a drain on your wallet... depending how you look at it
