Almost all the INTERNATIONAL airlines are ADS-B. Also most new Boeings and Airbuses, even of domestic airlines are, but most turboprops, and smaller jet airliners (eg Embraer, Bombardier) and older airliners aren't, but they still appear on the list, but not on the map.
Do get one soon! I hope you will share on the network - data from Thailand will be much appreciated.
