Heading Select,
What series of the 737 did you want to fly on ?
Anyway, here is a mix or Classics and NG series.
Try Air Asia in Malaysia, Jet Airways or Spice Jet in India, Lion Air or Adam Air in Indonesia (not sure though if they still allow expats to work there but way I look at it, it's a training flight), Philippine Airlines is still operating the B737-300 series for domestic ops.
Good luck mate
