Having seen your posts on the other thread this is the most pragmatic one. CX is leaving pax and cargo (and pax bags) behind on the JNB -HKG (LHR is not the only service) due to cut cost engineering on the rollers. Trying to put PW's on all services without success. 744 RR and 777ER seem both to be limited to about 24C whilst others can take more, perhaps we need 748i's?!!!
