Finnair vs SAS (2026): Which Should You Actually Book?

Two four-star Nordic flag carriers, two diverging fortunes — one bet everything on a quiet Helsinki Asia hub that Russia's airspace closure gutted; the other clawed its way out of bankruptcy and switched alliances to come back swinging with free Starlink.

On paper Finnair and SAS look like twins: both Skytrax four-star, both classic-model carriers (AFR 54 vs 50), both selling a 30-inch-pitch, 17-inch-wide economy seat, and both leading their cheapest fare with a hand-baggage-only ticket — Finnair’s Economy Light and SAS Go Light each give you 8kg up top and nothing in the hold. But that surface symmetry hides two very different airlines in 2026. Finnair is the polished Helsinki operator whose entire reason for being — the short polar hop to Asia — was kneecapped when Russian overflight closed, forcing longer, costlier routings. SAS is the post-bankruptcy comeback story: out of Chapter 11, out of Star Alliance and into SkyTeam, flying a younger fleet (10.3 years vs 12.6) and rolling out perks Finnair is still only talking about. For the cheapest-seat traveller, the gap is real.

Network & hubs: the wounded Asia specialist vs the resurgent Scandinavian

This is the whole story for a lot of travellers. SAS is simply the bigger airline: 102 destinations across 336 routes versus Finnair’s 84 destinations on 248 routes, built around a Copenhagen hub (with strong Oslo and Stockholm bases) and pushing transatlantic — Newark, JFK — plus Asian flagships like Seoul and Mumbai. Finnair’s Helsinki hub was engineered for one elegant trick: the shortest polar shortcut between Europe and Asia. Then Russia closed its airspace, and that geographic advantage evaporated overnight. Finnair’s Asia network has been visibly reduced, routings to Tokyo and Shanghai stretched longer and pricier, and the airline has leaned harder on North America (JFK, Chicago) and leasing capacity out to plug the gap. If you’re flying to East Asia, Finnair still does it with a tidy single connection at HEL; for everywhere else, SAS’s reach and frequency usually win.

The free stopover: Finnair's quiet ace

Here Finnair holds a card SAS doesn’t have at all. The Finnair Helsinki Stopover programme lets you break your journey in Helsinki for anything from a few hours up to five nights at no extra airfare — you just build it as a multi-city booking on finnair.com, and Finnair even hands you self-guided 6-, 12- and 24-hour itineraries through the Design District and Ateneum. It turns a connection into a free mini-break. The catch, and it’s a big one for aifly readers: the cheapest Economy Light fare does NOT permit a stopover — you need at least a Classic fare, where one stopover is included (a second runs about €75). SAS has no equivalent branded programme; you can self-connect through Copenhagen or Stockholm, but there’s no free ‘stay a few nights’ product. If a Helsinki city break for zero added fare appeals, Finnair is the only one of these two that sells it.

The cheapest fare: what Light strips, and who's actually a deal

This matters most to anyone booking the bottom economy seat, and the two are near-identical in what they take away. Finnair Economy Light and SAS Go Light both give you 8kg of hand baggage, zero checked allowance, zero free seat selection, and a change fee in the same ballpark (Finnair €80, SAS €70). The one nuance worth knowing: on Finnair’s long-haul Standard fares (a notch up from Light) a 23kg checked bag and a meal are bundled — so the long-haul Light-to-Standard jump can be better value than it looks. On frequency-of-deals, the data is lopsided: our pricing tracker holds 4,138 SAS fare observations against just 1,038 for Finnair, with similar median levels (around €536 vs €532). Translation — SAS simply surfaces as a bookable Nordic deal far more often, especially out of the big Scandinavian airports. Finnair deals are rarer and tend to cluster on its Asia and US routes.

Connectivity: the perk that flipped

If you’d judged this from a year-old spec sheet you’d get it backwards. SAS is rolling out free Starlink wifi — the fast, low-latency satellite service — starting with its A320neo fleet and extending to the long-haul A350s through 2026, free to EuroBonus members (joining is free). Finnair, meanwhile, still runs older paid wifi with only a messaging tier free for loyalty members, and its CEO has said the airline is merely in talks with Starlink and Amazon, aiming to settle a connectivity strategy before the end of 2026 — meaning no Starlink hardware is flying yet. So for the next year, the modern free-wifi experience belongs to SAS, not the more ‘premium’-feeling Finnair. It’s a rare case where the comeback carrier out-equips the polished one.

Judge this from a year-old spec sheet and you'd get it backwards: it's the bankruptcy survivor, SAS, flying free Starlink — not the polished Finn.

Cabin & comfort: identical economy, very different business

Down the back, these two are clones: 30-inch pitch, 17-inch width, snack-included service, and the difference between Finnair’s seatback screens and SAS’s stream-to-your-own-device approach. Up front is where they part ways. Finnair’s flagship is the divisive Collins AirLounge on the A350 — a fixed-shell, non-reclining business seat in full 1-2-1 (every passenger gets aisle access) that converts to a flat bed by sliding the base forward. Reviewers either love the lounge-y versatility or hate the lack of recline; it’s a genuine love-it-or-loathe-it product. SAS counters with a more conventional, well-regarded long-haul SAS Business cabin on its young A350s, and last October relaunched a proper European Business Class (replacing the old SAS Plus) for short-haul. For the cheapest-seat crowd none of this is what you’re buying — but if you ever splurge, know that Finnair’s business class is an acquired taste and SAS’s is the safer bet.

Reliability & fleet: punctual Finn vs the younger comeback

Finnair wins the on-time contest: 84% on-time (Cirium 2025) against SAS’s 78%, and Helsinki is consistently one of the more punctual hubs among European peers — a real, bookable advantage if you have a tight onward connection. SAS’s number carries the residue of its brutal 2024–25 restructuring; the trend is improving but the operation still throws the occasional disruption. The fleet picture, though, favours SAS: an average age of 10.3 years versus Finnair’s 12.6, anchored by A320neos, A321LRs and a growing A350 fleet whose average age is barely four. Both are safe, modern, IOSA-grade operations — there’s no safety knock against either. Net: Finnair for the punctuality, SAS for the newer metal. Pick the one that matches whether your worry is a missed connection or an aging cabin.

Points & alliance: oneworld vs the new SkyTeam member

Your loyalty maths depends entirely on which ecosystem you live in. Finnair is oneworld (Finnair Plus), so its miles and status play nicely with British Airways, Qatar, American and the rest — and its Helsinki Finnair Lounge plus the Platinum Wing, complete with a working sauna, is one of the more characterful flagship lounges in Europe. SAS made the bigger move: it left Star Alliance and joined SkyTeam on 1 September 2024, retooling EuroBonus to slot in alongside Air France-KLM, Delta and the rest, and consolidating its Copenhagen lounge into a single large complex in late 2025. If you’re a Delta or Air France flyer, SAS is now your Nordic partner; if you’re BA or American, Finnair is. For status-chasers the practical takeaway is simple — follow your existing alliance, because both deliver solid lounge and earning value within their own.

So — which one?
