The Ukrainian Aviation Group was a Ukrainian informal monopoly alliance of three airlines owned by Privat Group and led by Ihor Kolomoyskyi. The group was founded in 2007 by combining Dniproavia, Aerosvit and Donbassaero; these airlines often provide each other with the opportunity to use each other's aircraft, with flights more than often being operated for Aerosvit (the alliance's largest carrier). When Privat Group acquired Ukraine's largest airline Ukraine International Airlines in February 2011 Privat Group had a near monopoly on the aviation business in Ukraine.
