Boeing 777-200

The 777-200 entered service in 1995 with United and was the first airliner certified for 180-minute ETOPS, the rule that let twin-engine jets fly long routes across oceans. United and American fly most of those in this data.

What the figures say

Boeing 777-200 ranks 22 of 25 types for seat-miles per gallon in 2025, at 62.4. The Boeing 737-800, the most common type in the table, flew 79.1, so a gallon on the Boeing 777-200 carried a seat 21% less far. Over 1,000 miles, one seat on this type accounts for about 156 kg of CO2 from the fuel burned.

US airlines burned 1,163 million gallons on the Boeing 777-200 in 2025, 6.2% of the fuel burned on all scheduled passenger flying, over 482 thousand airborne hours and 63 thousand departures. The average flight spent 7.6 hours in the air and burned 18,385 gallons.

Since 2000, when it was first flown in volume, the type's figure has risen from 59.9 to 62.4 seat-miles per gallon (4.1%). Its best year was 2020, at 64.3. The average flight got longer, from 6.6 to 7.6 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.

Airlines get different results from the same aircraft. United Airlines flew 63.9 seat-miles per gallon on it and American Airlines 59.1, a gap of 8.1%. The seat count explains most of it: United Airlines put 295 seats on each flight against 272 at American Airlines. Flights were about the same length at both airlines, 7.5 and 8.0 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.
