I did search to see if I could find any discussion on this and found no results, so if this has been discussed, please let me know.

I am going to be flying HKG-JNB next month; scheduled on an Airbus A340 (34B). At least the return JNB-HKG is confirmed in business. I'm hoping the mileage gods will open up space on the outbound. We'll see.

But my question is... does anyone have any comments about flying the 34B vs. the 33B in either Y or J? I flew the 33B NRT-HKG a few months ago in J and quite enjoyed it.

The J seats according to seatguru are virtually the same... although the 33B has more of them!

If you had the choice on a given route, which aircraft would you pick?
Also curious about comments of Y class on both aircrafts. Would I assume correctly they're very similar products?

Thanks for any comments or thoughts. Lanny
