The airline Ukraine International Airlines, more known as flyUIA, is the largest carrier of Ukraine. It exists since 1992. The founders of the line were: Ukrainian Civil Aviation Organization and the Irish leasing company – Guinness Peat Aviation. The additional shareholders of Ukraine International Airlines became in 1999 two well-known carriers: Austrian Airlines and Swissair, and a year later they were joined by the European Bank for Reconstruction and Development. The airline was established as a joint-stock company, and in 2011 it was fully privatized. It was the first airline in the Commonwealth of Independent States to be awarded the IATA Safety Audit Certificate (IOSA) certificate and enlisted on the IOSA register.
The airline supports domestic, European, the Middle East and North America connections. After the bankruptcy of its competitor Aerosvit, that airline has taken over many connections, including to Warsaw. In 2001, it was chosen as the official carrier of Pope John Paul II during his visit to Ukraine.
