What the figures say

Boeing 787-10 ranks 5 of 25 types for seat-miles per gallon in 2025, at 86.2. The Boeing 737-800, the most common type in the table, flew 79.1, so a gallon on the Boeing 787-10 carried a seat 9.0% further. Over 1,000 miles, one seat on this type accounts for about 113 kg of CO2 from the fuel burned.

US airlines burned 183 million gallons on the Boeing 787-10 in 2025, 1.0% of the fuel burned on all scheduled passenger flying, over 93 thousand airborne hours and 11 thousand departures. The average flight spent 8.4 hours in the air and burned 16,522 gallons.

Since 2019, when it was first flown in volume, the type's figure has fallen from 91.5 to 86.2 seat-miles per gallon (5.8%). Its best year was 2020, at 93.2. The average flight got longer, from 6.4 to 8.4 hours in the air, which tends to lower fuel burn per seat-mile, because take-off and climb take a larger share of the fuel on a short flight. Fuel per airborne hour rose 7.2%, from 1,844 to 1,976 gallons.

How to read this. Fuel is what airlines issued to the type in 2025, as filed with the US Bureau of Transportation Statistics, counted only for the hours spent on scheduled passenger flights and divided by the hours in the air. It includes fuel burned taxiing and holding, so it's higher than the cruise figure in a manual. CO2 is 9.75 kg per gallon of jet fuel.
