AirOnix was a Ukrainian airline that operated scheduled and charter passenger services. The carrier was based in Kyiv and focused primarily on domestic Ukrainian routes as well as select international destinations within the region. The airline held IATA code OG and operated during the 2000s, serving as one of several smaller carriers in Ukraine's competitive aviation market. Like many regional Ukrainian airlines of the era, AirOnix faced significant commercial challenges in sustaining operations. The airline ultimately ceased operations, a fate shared by numerous smaller Ukrainian carriers that struggled to compete against larger national and international airlines serving the Ukrainian market.
