Boeing 757-200

What the figures say

Boeing 757-200 ranks 19 of 25 types for seat-miles per gallon in 2025, at 68.5. The Boeing 737-800, the most common type in the table, flew 79.1, so a gallon on the Boeing 757-200 carried a seat 13% less far. Over 1,000 miles, one seat on this type accounts for about 142 kg of CO2 from the fuel burned.

US airlines burned 431 million gallons on the Boeing 757-200 in 2025, 2.3% of the fuel burned on all scheduled passenger flying, over 347 thousand airborne hours and 123 thousand departures. The average flight spent 2.8 hours in the air and burned 3,497 gallons.

Since 2000, when it was first flown in volume, the type's figure has risen from 68.2 to 68.5 seat-miles per gallon (0.5%). Its best year was 2021, at 74.7. The average flight got longer, from 2.7 to 2.8 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. Delta Air Lines flew 69.8 seat-miles per gallon on it and United Airlines 68.6, a gap of 1.8%. The seat count explains most of it: Delta Air Lines put 192 seats on each flight against 176 at United Airlines. Flight length differs too, at 2.2 hours in the air per flight for Delta Air Lines and 4.8 for United Airlines. Longer flights normally burn less fuel per seat-mile, so the longer flights at United Airlines should have helped it, not hurt it. 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.
