Just an update...
I have chosen to fly CP instead of CX. Most important factor is the 65" inch pitch. It is a big difference compared to the 50" if it is a 13 hr flight.
However, I think CX's in flight entertainment and food is probably better than CX. I'll probably try them out on my next trip to HK early next year, hopefully they'll have the new first class then.
However, thanks for all the comments.
Regards,
Empress
