I agree. This is also the route I fly. The AF hard product to Bangkok is often dreadful. Whereas most of their aircraft now flying the transatlantic route, to the US, are excellent. That's a recent, vast improvement.
The AF, business class, soft product (service) I always find outstanding, either direction, Paris Bangkok or Paris US. Especially compared to the business "service" to be found on the US carriers, in my experience.
