739ER,
You are very lucky to have a contract that pays what it does. Sorry, I know the limit is 110 a month for part 121 operators in Indo.
Much of my info comes from Lion crew (locals) who I get to speak to on a fairly regular basis. From what I'm told the local FO wage is nowhere near 50 juta a month (I thought you got local terms?).
Lion have a guy going into the DGCA almost everyday lobbying for the end of the 250 hour rule. There will be some changes in DGCA management very soon so anything could happen!
