I’ve been working on two new features for the pre-Farnborough issue of Flight, one on 777 and the other on the 747-8. While researching yesterday, I came across a very interesting fact. With the help of the Way Back Machine, the historical archive of the entire internet, I found that the range of the 777-300ER has increased almost 11% (7,175 nm to 7,930 nm) since 2001! The maximum takeoff weight increased 25,000 lbs in that same time as well without a change in fuel capacity. To boot, the 777-200LR had a 6% increase in range too.
See for yourself.
