In the early 70s, a typical VC10 westbound service operated as BA591 LHR-JFK-LAX-HNL-NAN-MEL and returned as BA592 MEL-SYD-NAN-HNL-LAX-JFK-LHR. For crews, it was a 15/16-day trip.
Around the same time, a typical eastbound service might have been LHR-BEY-BAH-CCU-SIN-PER-SYD; however, at that time there was great variety of different routes and stops through Europe and the Middle East.
The VC10 service across the Indian Ocean operated initially NBO-SEZ-CMB-HKG-TYO and back, and then later out of SA as JNB-SEZ-CMB-HKG-TYO and return. SEZ-HKG/HKG-SEZ was BA940/941, HKG-TYO/TYO-HKG BA910/911 and the NBO-SEZ/SEZ-NBO flight number varied, according to the LHR-NBO service that it extended.
The first services to SEZ on the VC10 were, I believe, in 1971; I first visited SEZ in July 1972.
