About CommutAir
CommutAir is a regional United States airline headquartered in North Olmsted, OH. The carrier operates under the IATA designator C5 and the ICAO designator UCA; air-traffic controllers address its flight crews on the radio with the callsign "COMMUTAIR".

Within the US air-travel ecosystem, CommutAir sits in the "Regional" segment. Regional carriers operate the smaller jets and turboprops that feed traffic into the major hubs. Most of their flights are operated under the brand of a major partner, but the safety oversight, crews, and aircraft remain the regional carrier's responsibility.

Booking & service notes
Schedules, fares, and aircraft assignments for CommutAir change frequently, sometimes weekly. The data on this page is intended as a stable reference for codes, headquarters, fleet scale, and hub list; for live availability, fare class rules, baggage policies, and seat selection, always consult the carrier's own booking system at www.flycommutair.com.
