Asia - SE Asia airport codes

Does anyone have a list of international airports in SE Asia? I'm going to be in Singapore and would like to run an ITA search for cheap fares from SIN so I can make a side trip, but don't know very many of the airport codes for the area.

Here's a start. Most of these are pretty self explanatory:
BKK
PNH
SGN
RGN
DPS (Bali)
CGK (Jakarta)
JHB (Johor Bahru)
KUL
VTE
KCH (Kuching)
BWN (Brunei)
MNL
CNX (Chiang Mai)
KMG (Kunming)
HAN
REP (Siem Reap/Angkor)
PEN (Penang)
USM (Koh Samui)
HKT (Phuket)

Thanks a lot.

You can get a list of all airports in any country via OpenFlights airport search:

Select the country you want from the pulldown, leave the rest blank, and hit "Search". If you want every airport in the country (incl. air bases, general aviation etc), uncheck "Show only major airports".
