It would take me a while to thumb through them all - maybe someone has better recollection of exactly which issue - but there was a full article about all this in Propliner magazine some 10-15 years ago, about the introduction of the Britannia into El Al service.
One thing that sticks in my head is their ops team ran daily paper "flights" for some 12 months prior to introduction, where they planned the flight on the basis of the weather forecasts (such as they were in those days) and then subsequently evaluated them in the light of reality, and when the aircraft was first introduced they calculated they were saving probably an hour of flight time by this prior experience.
** OK, I just looked through and found it.
The article "Record breaking Britannias - El Al's small yet very efficient Britannia operation" is in Propliner issue 30 dated Spring 1987.
The captain's name on the nonstop was Zwi Tohar. The article has various notes on how they managed routing and altitude. The non-stop flight was Dec 18/19 1957 by 4X-AGC, 6100 miles, 14h46m, average of 401 mph
