Cathay Pacific Asia Miles - LHR - SYD in biz class

I am looking to book a return flight LHR - SYD for next Feb. Are all planes out of LHR fitted with the NBC now? Also, any chance of the HKG - SYD planes being upgraded for this flight?
For future refernce, is there any way to look this up?

Many thanks

Most flights out of LHR have the new Business Class. There are the odd flights..but generally, about 90% of them are. There are 3 flights a day on some days, the rest are twice daily. You'd have to be more specific on particurlar days.

You may of course call CX res in the UK and ask which flights on which day specifically has the aircraft confirguration: 74B. This is the only aircraft type that is NOT equipped with the NBC.

What do you mean by "any chance of the HKG - SYD planes being upgraded for this flight?" All flights out of HKG to SYD have the NBC.

thanks Guy
