Tailwinds,
U are right, LionAir is expanding with their MD83s, but the wages is not good for expats. This company is good for those who is building hours. I would suggest you ValuAir in SIN (new start up) or Air Asia in Malaysia (B 737 operator), but I don't know their COS.
If you want to hang around JKT, try "CJ's" Bar, or "BATS" Bar. It's a nice n cool place, lots of expats there.
Good luck
