Moscow Sheremetyevo, Cherepovets, and Saint Petersburg Pulkovo are the top three Severstal airports based on our airline data. This may change if Severstal makes updates to their flight routes due to supply and demand.
Severstal does not have flights from Singapore Changi at the moment. There are scheduled flights with Severstal out of Ekaterinburg though (if you don’t mind flying from this airport). Flying with Pobeda is recommended if you still want to fly from Singapore Changi.
