Lensk, Irkutsk, and Chita are the top airports IrAero flies into and out of during the year.
IrAero does not have flights from Denpasar Bali Ngurah Rai at the moment. There are scheduled flights with IrAero out of Vladivostok though (if you don’t mind flying from this airport). Flying with Aeroflot is recommended if you still want to fly from Denpasar Bali Ngurah Rai.
