What explains the differences

It's number 89 of the 100 busiest city pairs by passengers, and number 24 for the lowest CO2 per mile flown (0.14 kg per passenger-mile, number 1 being the lowest). A typical route of 861 miles in this set comes out at about 134 kg, so this one is 12% below it.

The airlines on this route differ by 38% per passenger. Frontier Airlines burned 1,810 gallons per flight and 180 passengers on each, and American Airlines 2,110 gallons and 152 passengers. Fuel burned per flight explains about 48% of the gap and the number of passengers on each flight the other 52%. Frontier Airlines flew 84% full here against 85% for American Airlines, flying mostly Airbus A321neo against Airbus A321.

For comparison, the EPA default factor for a flight of this length (0.129 kg per passenger-mile) would give 111 kg. The EPA figure is a national average for flights of that length. The measured figure for this route is 6.3% higher.

2019 compared with 2025

In 2019 the route carried 1.9 million passengers on 11 thousand flights. In 2025 it carried 1.7 million, down 8%, on 11 thousand flights, down 7%. The average flight had 184 seats then and 190 now, and 88% of them were filled against 84%.

CO2 per passenger was 122 kg in 2019 and 118 kg in 2025, down 3.4%. Fuel burned per flight was down 4.8% (2,033 gallons to 1,935) and passengers per flight were down 1.5% (162 to 160). The distance flown was about the same (861 miles then, 861 now).

American Airlines led in both years, with 42% of passengers in 2019 and 45% in 2025. Frontier Airlines gained the most share, 23% to 31%. Southwest Airlines lost the most, 17% to 10%.

Airline by airline, American Airlines went from 142 kg to 135 kg per passenger (187 seats per flight to 180, main aircraft Airbus A321 in both years); Spirit Airlines went from 104 kg to 104 kg per passenger (177 seats per flight to 193, main aircraft Airbus A320-200 then and Airbus A320neo now).

Fly or drive

Driving is about 1,007 miles by road, which we estimate as 1.17 times the straight-line distance. An average car emits about 299 kg of CO2 on the trip, at the EPA figure of 0.297 kg per vehicle-mile. Alone, that's 153% more than the 118 kg for a passenger on the flight.

With 3 people in the car, driving comes out lower per person than the flight (100 kg each, and 75 kg each for four). A larger SUV or pickup (0.394 kg per mile) would emit about 397 kg per vehicle.
