Airbus A320-200

The A320 first flew with passengers in 1988 and has been in US fleets for decades. This is the original-engine A320-200, flown today by JetBlue, Allegiant, United, Delta and Spirit.

What the figures say

Airbus A320-200 ranks 14 of 25 types for seat-miles per gallon in 2025, at 74.0. The Boeing 737-800, the most common type in the table, flew 79.1, so a gallon on the Airbus A320-200 carried a seat 6.4% less far. Over 1,000 miles, one seat on this type accounts for about 132 kg of CO2 from the fuel burned.

US airlines burned 1,124 million gallons on the Airbus A320-200 in 2025, 6.0% of the fuel burned on all scheduled passenger flying, over 1,170 thousand airborne hours and 554 thousand departures. The average flight spent 2.1 hours in the air and burned 2,031 gallons.

Since 2000, when it was first flown in volume, the type's figure has risen from 69.6 to 74.0 seat-miles per gallon (6.3%). Its best year was 2020, at 79.8. The average flight got shorter, from 2.4 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.

Airlines get different results from the same aircraft. Allegiant Air flew 84.1 seat-miles per gallon on it and American Airlines 62.4, a gap of 35%. The seat count explains most of it: Allegiant Air put 180 seats on each flight against 150 at American Airlines. Flight length differs too, at 2.1 hours in the air per flight for Allegiant Air and 1.7 for American Airlines, and longer flights burn less fuel per seat-mile, which helps Allegiant 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.

Similar-sized aircraft

These types carry within about 25 seats of the Airbus A320-200, so they compete for the same routes.

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.
