"Finncapt",
I think you are right about the London-New York-Los Angeles-Honolulu-Fiji-Sydney VC10 routing. I have a BOAC timetable somewhere but can't locate it immediately to check!
I recall a most memorable landing as a passenger at LAX on a Super VC10 from JFK: it was in the evening of 4 July, 1972 (Independence Day) with one of those gorgeous southern Californian summer sunsets. What made it memorable is that I'd never before arrived at an airport with parallel runways where both were being used for landings. A Western Boeing 720 was at our side as we descended.
The return LAX-JFK leg was a night transcontinental crossing - barely 5 hours in the Super VC10 - with the aircraft then operating the morning JFK-LHR run. What I remember about the landing at JFK was how "firm" it was.
