NM - just to add to what you wrote about QF.

QF has never had a fatal jet accident. The last crash that I could find recorded was on 16 July 1951, when seven of its pax died in a domestic New Guinea accident, a crash of a small prop plane flying in very difficult territory.

That does give QF more than 50 years without a pax dying in a flight accident, which is pretty good by any criteria.

Are we sure that CX has been fatal accident free? I vaguely remember at least one crash, but could be wrong.
