Good day mate, I work for the subsidiary of lion air. Hopefully i can shed some light for you.
As you are experienced you have a good chance of getting hired, I presume you will have to mail the company directly as the pay to fly scheme has been cancelled due to the new regulations in Indonesia.
Salary - it will depend on the contract you are given, my friends in lion take home an avg of 4-5 grand a month with 90-110 hours of flying.
commuting - we are all based in Jakarta, you will start your flights from Jakarta and carry on flying and ron at your destination.
housing - depends again on your contract, as far as i am aware the foreign pilots have an allowance of 4million idr ( roughly 400 usd)
Hope this helps
