Novosibirsk Tolmachevo, Irkutsk, and Moscow Domodedovo are the top three S7 Airlines airports based on our airline data. This may change if S7 Airlines makes updates to their flight routes due to supply and demand.
S7 Airlines does not have flights from Singapore Changi at the moment. There are scheduled flights with S7 Airlines out of Bangkok Suvarnabhumi though (if you don’t mind flying from this airport). Flying with Ethiopian Air is recommended if you still want to fly from Singapore Changi.
