Thai Airways Royal Orchid Plus - Best Business Equipment HKG-BKK / BKK-JNB?

I'm on a *A RTW in Business with my family.

I have upcoming flights HKG-BKK and BKK-JNB.

Since there are a number of flights any recommendations on the HKG-BKK flight?

Any thoughts on what to expect for the BKK-JNB leg compared to other *A carriers with a different routing?

You'll be on board a 777-200 or -300. Seat should be like the one found here (http://www.thaiairways.com/thai-services/in-the-air/en/Sogerma/seat02_vFinal.html). It's a good bus class seat, without being great.

For an 11 hour flight, I'd probably prefer the bus class seats TG has on the 7443 and the A340s, and I'd definitely prefer the seats they have on the 777-300ER.

Service on TG can range from the simply outstanding to the reasonably ordinary. Personally, I've had far, far more good TG service experiences than bad. Of course, if you travel enough you're going to experience the ups and downs of travel on any airline.

Seatguru lists Flight 991 BKK-JNB as the 777, so I assume that's what you are suggesting is the best equipment I'm likely to find?
