Airbus A330-900

The A330-900 is the A330neo: the fuselage length of the A330-300, a longer wing and new Trent 7000 engines. In this data Delta flies it, so it compares directly with the A330-300.

What the figures say

Airbus A330-900 ranks 9 of 25 types for seat-miles per gallon in 2025, at 78.6. The Boeing 737-800, the most common type in the table, flew 79.1, so a gallon on the Airbus A330-900 carried a seat 0.7% less far. Over 1,000 miles, one seat on this type accounts for about 124 kg of CO2 from the fuel burned.

The older Airbus A330-300 flew 69.4 seat-miles per gallon in 2025. The Airbus A330-900 is 13% ahead, with 281 seats per flight against 282. Its fuel burn per airborne hour is 1,844 gallons against 2,088.

US airlines burned 320 million gallons on the Airbus A330-900 in 2025, 1.7% of the fuel burned on all scheduled passenger flying, over 173 thousand airborne hours and 20 thousand departures. The average flight spent 8.6 hours in the air and burned 15,769 gallons.

Since 2021, when it was first flown in volume, the type's figure has fallen from 79.5 to 78.6 seat-miles per gallon (1.1%). Its best year was 2024, at 79.5.

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.
