Republic Airways

How it changed

Republic Airways carried 21.3 million passengers in 2025, its busiest year in this data.

Its average flight had 72 seats in 2005 and 75 in 2025. The average passenger flew 665 miles per segment in 2005 and 492 in 2025, and 78% of its seat-miles were filled in 2025.

Who it flew for

Republic Airways 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

Republic Airways operated 249 passenger aircraft of its own in 2025. The average age was 13.9 years: 14% of the aircraft were under five years old and 19% were twenty or older. The oldest was an Embraer E170 built in 2004.

In 2007 the average age was 0.8 years across 57 aircraft. It's older now by 13.1 years, and the fleet is bigger.

Model	Aircraft	Average seats	Average age

Fuel

In 2025 Republic Airways burned 322 million gallons of jet fuel, which is 41.5 seat-miles per gallon and about 0.300 kg of CO2 per passenger-mile. Over 500 miles that's roughly 150 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.
