About IO
IrAero (IATA: IO) is a Russian regional carrier that does exactly what the name implies — it connects the parts of Russia that other airlines treat as afterthoughts. Its main hub is Irkutsk (IKT), deep in eastern Siberia, and the network fans out from there across some of the most logistically awkward geography on the planet. With 128 non-stop routes spanning 46 airports and a total network distance of 185,702 km, this isn't a boutique operation. It's the kind of airline that exists because the Trans-Siberian Railway isn't always the answer.
Why fly IO?
The honest case for IO is geography, not glamour. If you're trying to reach somewhere in Russia's far east or connect through Irkutsk without routing through Moscow twice, IO is often your only realistic option. The international reach is modest but purposeful — five routes into Azerbaijan, three into China, one into Mongolia — which tells you this is an airline serving real trade and family corridors, not aspirational tourism routes. The longest route, KYZ to DME at 3,653 km, gives you a sense of the distances involved. You're not flying IO for the soft product. You're flying it because it goes where you need to go, and that's a genuinely underrated quality in aviation.

Tips for booking IO
Book early on thinner routes out of secondary hubs like Chita (HTA) or Blagoveschensk (BQS) — eight and nine routes respectively, which means limited frequencies and not much fare competition to keep prices honest. The Irkutsk hub is your best bet for schedule flexibility, with 16 routes giving you more options if something shifts. IO isn't part of a major global alliance, so don't count on earning miles with your usual program or using partner lounges. First-time flyers should treat this like a domestic Russian regional: check baggage rules carefully, keep expectations calibrated to the route type, and have backup plans for weather disruptions in winter.
