Airbus A320neo

The A320neo is the A320 with new, more efficient engines, in service since 2016. In the US it's flown mainly by Frontier and Spirit, two ultra-low-cost airlines.

What the figures say

Airbus A320neo ranks 2 of 25 types for seat-miles per gallon in 2025, at 100.6. The Boeing 737-800, the most common type in the table, flew 79.1, so a gallon on the Airbus A320neo carried a seat 27% further. Over 1,000 miles, one seat on this type accounts for about 97 kg of CO2 from the fuel burned.

The older Airbus A320-200 flew 74.0 seat-miles per gallon in 2025. The Airbus A320neo is 36% ahead, with 182 seats per flight against 163 (more seats account for part of the gap). Its fuel burn per airborne hour is 780 gallons against 961.

US airlines burned 293 million gallons on the Airbus A320neo in 2025, 1.6% of the fuel burned on all scheduled passenger flying, over 376 thousand airborne hours and 176 thousand departures. The average flight spent 2.1 hours in the air and burned 1,662 gallons.

Since 2019, when it was first flown in volume, the type's figure has fallen from 100.7 to 100.6 seat-miles per gallon (0.1%). Its best year was 2020, at 105.1. The average flight got shorter, from 2.3 to 2.1 hours in the air, which tends to raise 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 fell 5.4%, from 824 to 780 gallons.

Airlines get different results from the same aircraft. Spirit Airlines flew 101.1 seat-miles per gallon on it and Frontier Airlines 100.2, a gap of 0.9%. It isn't the seat count: Spirit Airlines put 176 seats on each flight and Frontier Airlines 186. Flights were about the same length at both airlines, 2.2 and 2.1 hours in the air. What's left comes from taxi and holding time, weight, engines, how each airline operates and how it allocates fuel to types when it reports, and the filings can't separate those.

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.
