Based on flight volume data, Novosibirsk Tolmachevo is the most popular airport that AeroUnion uses. Polyarnyj and Mirnyj are the next two most visited by AeroUnion.
No, you will need to book a flight with AeroUnion out of Irkutsk because the airline doesn’t have scheduled flights from Bangkok Suvarnabhumi at this time. If you still wish to fly from Bangkok Suvarnabhumi, then consider booking with เอสเซเว่น แอร์ไลน์.
