US Airline fuel burn improvement continues |

With the DOT's year-end 2024 T2 update published, we have updated our models using this source. Airlines are on a continual hunt for better fuel burn. Fuel represents about 45% of operational costs. Below is one of these models that shows airlines and aircraft fuel burn. The US airline industry continues to show steady fuel burn improvement over time. Its fleet updates primarily drive this. Newer aircraft are remarkably fuel-efficient compared to the previous generation. Our analysis suggests fuel burn is well over the 16% typically promised. It also helps, of course, that airlines have added more seats. What was a 150-seater in the previous generation is more like a 170-seater. Drive the model to see how the industry has improved its fuel efficiency. Notes: There are two pages to review, and using the menus allows a reader to tweak the models. Note that the bubble charts have a "play" button at the bottom left, allowing the model to animate over the period. The dashed lines are averages that change as you use the menus. ASMs drive the ball sizes. Typically, the best quadrant is to the upper right, and the worst quadrant is the lower left. You will note that older generation aircraft are to the lower left and the state-of-the-art aircraft are to the upper right.
