From the Bangkok Post 6 Feb:
"THAI will shift the Boeing B737-400s it uses on the Bangkok-Bandar Seri Begawan (Brunei) route to the Bangkok-Samui route instead, according to THAI executives.
But the shift means the airline would no longer be able to operate its own aircraft on the Bangkok-Bandar Seri Begawan route. Now it operates three flights a week with B737-400s.
THAI will transfer its passengers on the Bangkok-Bandar Seri Begawan route to code-share partner Royal Brunei Airlines, which continues to operate on the route."

No information about this so far from TG although it appears the last TG flight is 10/02. At the moment they do NOT code share with Royal Brunei. OK, the planes are poor, but at least we could link into the main TG system. This will make it more expensive and inconvenient.
