Emirates. I flew with them last year, although on the BKK-DXB service (same flight). They are usually "cheap".
Also (don't know about prices):
Thai Air Int
Best to have a look on something like Expedia or Travelocity to find cheap fares. The latter has a good "cheapest day" finder where you can enter a month range and it'll find the cheapest fares over that date range.
