Last Nov, there was 1st class service on the Hong Kong to Jakarta run. True, it was the 'old' first class on an A-340, did not matter as there were only 3 of us in first for both legs. Also, there was an A-330 nonstop to NRT with all 3 classes and had the special Japanese meal service and new business class seats. I believe that there is a first class service on the HKG-BKK-SIN flight. Not really long enough to enjoy it though.
