JetBlue

The story in the figures

JetBlue's passenger-miles per gallon rose 14% between 2000 and 2025, from 56.7 to 64.8. Most of that came from fuller planes: planes ran fuller, with 73% of seat-miles filled in 2000 against 82% in 2025, while seat-miles per gallon rose 1.1%.

The shape of the flying changed as well: the average passenger flew 884 miles per segment in 2000 and 1,357 in 2025. In general, longer flights spend a smaller share of their fuel on takeoff and climb.

Its best year was 2005, at 66.6 passenger-miles per gallon, and its latest figure sits 2.7% below that.

In 2020 the pandemic emptied the cabins: load factor dropped from 84% to 57%, and passenger-miles per gallon fell from 60.5 to 45.1. A flight burns most of its fuel whether the seats are full or not, which is why an empty year looks so bad per passenger. By 2025 the figure was 7.1% above its 2019 level.

Against the all-airline figure for 2025 (60.6), JetBlue was 7.1% better. On a 1,000 mile trip that works out to 150 kg of CO2 for one passenger, from burning jet fuel only.

The JetBlue fleet

JetBlue operated 291 passenger aircraft of its own in 2025. The average age was 11.6 years: 29% of the aircraft were under five years old and 25% were twenty or older. The oldest was an Airbus A320 built in 1999. That's the 6th youngest of the 12 airlines ranked here.

In 2006 the average age was 2.2 years across 119 aircraft. It's older now by 9.4 years, and the fleet is bigger.

On the Airbus A320, JetBlue fits 161 seats on average, against a median of 157 at the other airlines that fly it (142 to 184). 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.

JetBlue aircraft by model, 2025

Model	Aircraft	Average seats	Other airlines, median seats	Average age
Airbus A320	130	161	157	19.8
Airbus A321	63	177	222	9.1
Airbus A220-300	59	140	137	1.5
Airbus A321neo	39	170	220	3.3
