About Mesa Airlines
Mesa Airlines is a regional United States airline headquartered in Phoenix, AZ. The carrier operates under the IATA designator YV and the ICAO designator ASH; air-traffic controllers address its flight crews on the radio with the callsign "AIR SHUTTLE". The airline was founded in 1982 and currently operates a fleet of approximately 80 aircraft.
Within the US air-travel ecosystem, Mesa Airlines 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.

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.mesa-air.com.
