Due to the current Covid-19 pandemic, all regular services and hours may be subject to change. Thus, if the idea is to spend the night in the public area, consider a plan B in case the stay inside the airport is only allowed for those who are close to boarding.
Spending the night at the airport
Irkutsk airport is open 24 hours a day, so you can spend the night inside the enclosure if you have a flight early in the morning or if your flight is delayed.
Where to rest: There are some seats inside the terminals, but these have armrests, so you will probably be more comfortable sleeping on the floor (especially with a sleeping bag or blankets). Inside both terminals there are also VIP lounges that are open 24 hours a day. However, the maximum stay is 3 hours. A few meters away from the enclosure there are a few hotels if you want more privacy.
Baggage: Left-luggage services are available inside both terminals.
Eating and drinking: Available options close at night.
Other services available around the clock: ATMs, baby changing room.
