It's impossible to answer this conclusively. Prices depend on specific flights, booking time, whether you need check-in luggage etc. For the best price, you'll need to search every time you fly.
City pairs that are geographically close and have low-cost flights are generally, but not always cheaper. For example, Chiang Rai to Kunming; Hat Yai to Kuala ...
