2025 profileAir Wisconsin
Air Wisconsin is based in Appleton, Wisconsin, and began flying in 1965. It has flown under the brands of several airlines: United Express, then US Airways Express from 2005, American Eagle from 2015, United Express again from March 2018, and American Eagle again from 2023. That last contract ended on 3 April 2025, and the airline said it would move to charter and Essential Air Service flying. In this data its passengers peaked at 7.2 million in 2004 and were 0.4 million in 2025, on 50-seat CRJ200 jets.

How it changed
Air Wisconsin carried 0.4 million passengers in 2025. Its busiest year was 2004, at 7.2 million.
Its average flight had 58 seats in 2000 and 50 in 2025. The average passenger flew 329 miles per segment in 2000 and 256 in 2025, and 78% of its seat-miles were filled in 2025.
Who it flew for
Air Wisconsin flew for more than one airline, and sometimes several at once. Our estimate of the split between them, which is based on the airports it serves, is too rough to publish for a regional like this. The summary at the top names its partners from public record.
The fleet
Air Wisconsin Airlines operated 54 passenger aircraft of its own in 2025. The average age was 22.8 years: 0% of the aircraft were under five years old and 100% were twenty or older. The oldest was a Bombardier CRJ-200 built in 1998.
In 2006 the average age was 4.1 years across 70 aircraft. It's older now by 18.7 years, and the fleet is smaller.
Air Wisconsin aircraft by model, 2025
| Model | Aircraft | Average seats | Average age |
|---|---|---|---|
| Bombardier CRJ-200 | 54 | 50 | 22.8 |
Fuel
In 2025 Air Wisconsin burned 4 million gallons of jet fuel, which is 31.4 seat-miles per gallon and about 0.398 kg of CO2 per passenger-mile. Over 500 miles that's roughly 199 kg per passenger. Small regional aircraft burn more fuel per seat than the mainline jets, and a short hop spends a larger share of its fuel on take-off and climb, so these figures aren't graded against the airlines on the main list. Their flying and fuel are counted in the airlines whose names are on the tickets.
