I have noticed that on the flights from London to the US East Coast , British Airways usually uses its Boeing 747-400 aircraft with the G-BNLA through Z registrations.
Therefore, I had assumed, these must be the "lite"-designated aircraft which are used for shorter flights that do not require so much fuel.
Yet, in pictures on this website, I have seen pictures of the G BNL series aircraft in cities such as Sydney and Hong Kong, which are much longer routes, suggesting that these aircraft are NOT the "lite" aircraft.
Does any one have any information? Or is my information wrong and all the BA 747-400s have the identical range and fuel capacity?
