The story in the figures
Avelo Airlines' passenger-miles per gallon fell 2.9% between 2023 and 2025, from 63.8 to 62.0. Most of that came from fuller planes: planes ran emptier, with 80% of seat-miles filled in 2023 against 76% in 2025, while seat-miles per gallon rose 2.9%.
Against the all-airline figure for 2025 (60.6), Avelo Airlines was 2.3% better. On a 1,000 mile trip that works out to 157 kg of CO2 for one passenger, from burning jet fuel only.

The Avelo Airlines fleet
Avelo Airlines operated 22 passenger aircraft of its own in 2025. The average age was 16.8 years: 0% of the aircraft were under five years old and 18% were twenty or older. The oldest was a Boeing 737-700 built in 2003. That's the oldest fleet of the 12 airlines ranked here.
In 2006 the average age was 10.0 years across 6 aircraft. It's older now by 6.8 years, and the fleet is bigger.
On the Boeing 737-800, Avelo Airlines fits 189 seats on average, against a median of 172 at the other airlines that fly it (154 to 183). Seats on the same aircraft are one reason fuel per seat and fuel per passenger differ between airlines: the fuel burned by a given plane is much the same, and more seats share it.
