I just did CX SYD(HKG)DXB RTN in J. Unfortunately no F on A33B which does those sectors but I did have my bags tagged First Class each sector and purser did come up to me personally and introduce herself on each of 4 flights and come up to me and ask if all was OK on two sectors, even did my meal service on a couple of occasions.

I found the entire trip with CX faultless and very very pleasant. When the new J class is introduced I can only image it will be even better. Only down side was the food, I didn't think that was better than QF or their F lounge in HKG.

Until QF comes up with a new Middle East partner(if ever) it will be CX for me all the way.^
