Ufa, Novy Urengoy, and Tyumen are the top three UTair airports based on our airline data. This may change if UTair makes updates to their flight routes due to supply and demand.
UTair does not have flights from Singapore Changi at the moment. There are scheduled flights with UTair out of Osh though (if you don’t mind flying from this airport). Flying with Ural Airlines is recommended if you still want to fly from Singapore Changi.
