Occasionally jobs do come up.
About 18 months ago Thai Air Asia were hiring expat pilots for permanent positions based in BKK on local rates. (About THB120K per month.) Don't know if any of those guys are still there but my guess is they were used as cheap disposable plugs while the locals were being trained up.
Better to work elsewhere, me thinks, and R&R in LOS.
Ahh...Soi33. Some treasures down there
