Air Onix (OG, Simferopol) has been suspended by IATA from participating in its clearing house as "the airline has ceased operations." This will no longer allow travel agents to issue any new tickets on Air Onix flights booked through global distribution systems and settled through IATA's Billing and Settlement Plan. On December 13, Air Onix had issued a statement saying it would "optimize" its flight schedule by cancelling its daily Donetsk-Kiev Zhulyany until further notice because of the current political situation in Ukraine. According to ch-aviation research, Air Onix has actually not operated any flights with its B737-300 UR-KRA (msn 28873) and B737-400 UR-KRE (msn 26302) since December 13. The airline however continues to sell tickets for its routes from Kiev Zhulyany to Bratislava and Simferopol and from Simferopol to Tel Aviv Ben Gurion and Yerevan through its website.
