BnE is well serviced by QF at fares below those of CX. just avoid QF 787 as their 9 abrest is atkin to CX 777 10 abrest in economy that does service BNE once in a while.
i do agree CX A350 is great bird, saving grace of an otherwise Cathay pathetic. but CX owns too much 777 so odds of ending up with their 10abrest is higher than 350s
