S7 Airlines, legal name JSC Siberia Airlines, is Russia’s largest privately owned airline by passenger traffic, tracing its roots to 1957 and rebranded under the S7 name in 2005. Since Russia’s 2022 invasion of Ukraine, S7 has been banned from EU airspace and had its oneworld alliance membership suspended, and it can no longer take delivery of new Western-built aircraft or source parts for its existing Airbus fleet, significantly reshaping its operations around the domestic Russian market.

Siberia Airlines Route Network
S7’s network today is overwhelmingly domestic, connecting its Novosibirsk and Moscow bases to cities across Russia, with international service limited to destinations in countries that remain open to Russian carriers.
Primary Hub
Novosibirsk Tolmachevo Airport (OVB) & Moscow Domodedovo (DME)
S7 operates dual hubs at Novosibirsk Tolmachevo Airport (OVB), its historical home base in Siberia, and Moscow Domodedovo Airport (DME).
Alliance & Partner Airlines
S7’s oneworld membership has been suspended since April 19, 2022, following sanctions related to Russia’s invasion of Ukraine, meaning oneworld mileage earning, redemption, and lounge benefits currently don’t apply to S7 flights.
Baggage, Seating & Onboard Amenities
A quick reference before you pack — always confirm exact allowances on your fare rules at booking, since they vary by route and cabin.
Carry-On & Personal Item
Carry-on allowances generally follow standard international norms, though confirm current policy directly given the airline’s more limited international distribution today.
Checked Baggage
Checked baggage rules vary by fare and route; because S7’s international ticket distribution outside Russia is limited, confirm current baggage policy directly with the airline.
Excess Baggage Fees
Overweight, oversized, or extra bags typically incur a per-bag fee charged at check-in or online in advance — pre-paying online is usually cheaper than paying at the airport.
Seat Selection & Cabin Classes
S7 operates a mixed Airbus and Embraer fleet on its domestic and remaining international routes, offering Economy and Business cabins depending on aircraft type.
How to Find the Cheapest Siberia Airlines Fares
Four habits that consistently lower what you pay.
Book in the Sweet-Spot Window
For most Siberia Airlines routes, fares tend to be most competitive when booked several weeks to a few months ahead of departure, rather than at the last minute or extremely far out.
Fly Midweek and Off-Peak
Tuesday, Wednesday, and Saturday departures are usually cheaper than Friday or Sunday, and red-eye or early-morning flights often undercut peak daytime departures.
Set Fare Alerts
Track your route and let price-drop notifications do the watching, instead of checking manually every day.
Price-Tracking Tip
Compare a fixed date range over a week or two before deciding — single-day price checks can be misleading.
Compare a fixed date range over a week or two before deciding — single-day price checks can be misleading.
Use Flexible Date Search
Searching a date range instead of one fixed day often surfaces Siberia Airlines fares that are noticeably lower just one or two days earlier or later.
Check-In & Day-of-Travel
Online Check-In
Online and mobile check-in generally opens 24–48 hours before departure, letting you select or confirm your seat and download your boarding pass in advance.
Airport Arrival Times
Arrive with enough buffer for check-in, bag drop, and security — this matters more on international Aegean Airlines routes than short domestic hops.
Domestic vs. International Cutoff
International check-in and bag-drop counters usually close earlier relative to departure than domestic ones, so double-check your specific route’s cutoff.
Frequently Asked Questions

S7 Airlines' IATA code is S7, with ICAO code SBI. It was formerly known as Siberia Airlines.
S7's oneworld membership has been suspended since April 19, 2022, following sanctions related to Russia's invasion of Ukraine — it remains a suspended (not expelled) member, but oneworld benefits currently don't apply.
Yes, like other Russian carriers, S7 has been banned from EU airspace since 2022 as part of sanctions imposed following Russia's invasion of Ukraine.

S7's remaining international network is limited to destinations in countries that remain open to Russian carriers, a much smaller footprint than before 2022.
Ticket distribution and payment options outside Russia are limited due to sanctions, so availability through international booking channels is inconsistent — confirm directly with the airline before assuming a fare is bookable.
