... both the Norwegian and the Scatsta operations do not routinely undertake extreme long range flights such as ABZ-EGPB-ESB-EGPB-ABZ which one could infer place considerable strain of the operational infrastructure of those Companies that do.
Interesting.
There have been comparisons with Norwegian, GoM and Bass Strait operations and I wonder if distance may be an important factor. Although there are a few long flights in those territories, doesn't most of the work, particularly historically, consist of flights that are short compared to the UK.
