The story in the figures
National Airlines' passenger-miles per gallon rose 9.2% between 2000 and 2002, from 42.7 to 46.6. Most of that came from fuller planes: planes ran fuller, with 65% of seat-miles filled in 2000 against 69% in 2002, while seat-miles per gallon rose 2.6%.
Against the all-airline figure for 2002 (40.3), National Airlines was 16% better. On a 1,000 mile trip that works out to 209 kg of CO2 for one passenger, from burning jet fuel only.
