How to recognize the airline

Is that really SAS Scandinavian Airlines?

Check off everything that applies to the aircraft you’re looking at right now.

  • Blue tail with the white SAS logo; the blue extends into the rear fuselage
  • Light fuselage with a large, silver “SAS” title up front
  • “Scandinavian” title in blue on the engines and in large letters on the underside of the fuselage – easy to see on a flyover
  • Registrations from three countries: OY- (Denmark), SE- (Sweden), LN- (Norway); plus EI- at SAS Connect
  • Almost all Airbus on the main routes, plus the Embraer E195 and wet-lease types such as the CRJ900 and ATR 72-600
  • Every aircraft carries a Viking name on the fuselage, such as “Frederik Viking”

When an aircraft with a blue tail and the word “Scandinavian” on its belly floats in over Hamburg or Frankfurt, the identification is quick. It only gets interesting afterward: does the jet carry a Danish, Swedish or Norwegian registration, does it belong to the Irish subsidiary SAS Connect – or is it not a SAS aircraft at all, but a wet-lease partner? This page shows you how to classify SAS cleanly and what matters after the alliance switch.

SAS at a glance

SAS is the joint network carrier of Denmark, Norway and Sweden. It was founded on August 1, 1946, when the three national carriers pooled their transatlantic traffic. Still in the same year it started flying to New York – a route SAS marked with anniversary flights to New York for its 80th birthday in September 2026. The merger later grew into a full airline with a domestic, European and long-haul network.

The company is headquartered in Frösundavik in Solna near Stockholm. Instead of a single hub, SAS works with three: Copenhagen is the most important, joined by Stockholm Arlanda and Oslo. This split reflects its origins – each of the three countries has its own hub.

The last few years have been turbulent. In July 2022 SAS filed for Chapter 11 bankruptcy protection in the US and went through a long restructuring. It was completed in 2024 with new owners: the financial investor Castlelake, Air France-KLM, the Danish state and Lind Invest. Norway had already sold its shares in 2018, and Sweden withdrew in the course of the restructuring.

Codes and callsign

  • IATA code SK: appears in the flight number, so on the departure board, ticket and in most schedules.
  • ICAO code SAS: appears in the air traffic control flight plan and on flight trackers for flights of the main company.
  • Callsign SCANDINAVIAN: this is how the crew identifies itself on the radio.
  • SAS Connect: its own ICAO code SZS, but flies under SK flight numbers.

With SAS, it stands out that the ICAO code and the brand name are identical – which makes tracker entries easy to read. It gets harder when you ask who actually operates an SK flight. Why flight number and callsign can diverge is explained in the article on the difference between callsign and flight number. The logic behind the abbreviations is covered in IATA and ICAO codes explained.

Reading the tracker correctly

If the tracker shows an SK flight with an ICAO code other than SAS, a subsidiary or a partner is flying on behalf of SAS. How to make good use of ADS-B data is shown in the guide to flight tracking for spotters.

From Star Alliance to SkyTeam

For spotters in Germany this is the biggest change of recent years. In 1997 SAS was one of the founding members of Star Alliance – together with Lufthansa, United, Air Canada and Thai. For decades SAS was thus a close partner of Lufthansa, and SAS aircraft stood in Frankfurt and Munich quite naturally around the Star Alliance terminals.

With the entry of Air France-KLM that changed. On August 31, 2024, SAS left Star Alliance, and on September 1, 2024, it joined SkyTeam. There, Air France, KLM and Delta are the big names. The differences between the three alliances are summarized in the overview of Star Alliance, oneworld and SkyTeam.

In July 2025, Air France-KLM announced it would raise its own stake from 19.9 to 60.5 percent by taking over the shares of Castlelake and Lind Invest. The Danish state remains a shareholder. Completion requires approval from the competition authorities, in particular the European Commission. Air France-KLM most recently named the second half of 2026 as its target – whether that works out depends on the review. Until then SAS is an independent airline with a strong major shareholder.

The fleet: Airbus, Embraer and partners

At first glance the fleet is tidy – at second glance it is a mix of the main fleet, subsidiaries and rented aircraft. According to SAS’s fleet overview (as of February 2024) it looks like this:

Type Number Seats Who flies it Spotter tip
Airbus A320neo 82 180 SAS and SAS Connect The backbone on European routes
Airbus A321LR 3 157 SAS Longer cabin, more range
Airbus A319 / A320 4 / 3 150 / 168 SAS Older generation with smaller engines
Airbus A330-300 8 266 SAS Long-haul, Rolls-Royce Trent 700
Airbus A350-900 6 300 SAS Long-haul flagship
Embraer E195 16 122 SAS Link Regional jet on shorter routes
Bombardier CRJ900 15 90 Wet-lease partner Rear-mounted engines, in SAS colors
ATR 72-600 12 70 Wet-lease partner Turboprop, mainly domestic

The figures are a snapshot. Since then the numbers – especially for the wet-lease partners – may have shifted. So take the table as a guide to the types, not as an exact headcount.

The largest share is the Airbus A320neo. With it, SAS has switched its short- and medium-haul fleet almost completely to Airbus; in September 2026 the airline reported that all 81 A320neos are equipped with Starlink internet. Alongside them still fly some older A319s and A320s as well as a handful of A321LRs – the long-range version of the A321neo.

On long-haul routes the A350-900 and the A330-300 are in service. The manufacturer of both types is Airbus. The Boeing 737, long SAS’s workhorse, has disappeared from scheduled service. There is one exception: for air ambulance flights of the Norwegian armed forces, SAS operates a converted Boeing 737-700 with stretchers and intensive care places – a rare catch for any logbook.

Only the A350 still missing?

The orders: E195-E2 and new widebodies

Two big orders shape the next few years. In July 2025 SAS agreed to buy 45 Embraer E195-E2s plus purchase rights for ten more. According to SAS, the first deliveries are planned for the end of 2027, with the rest spread over about four years. That gives SAS Link the successor generation of today’s E195.

In June 2026 came the largest order in the company’s history by list price: up to 40 Airbus widebody aircraft. These include new A330-900s for long-haul growth and additional A330-300s that bridge the time until the new fleet arrives. SAS has not published an exact split between the two types or firm delivery dates.

How to recognize the A330-900

  • Larger engines (Rolls-Royce Trent 7000) with a thicker nacelle
  • Curved “sharklets” on the wingtips
  • Listed as A339 on trackers

How to recognize the A330-300

  • Slimmer engines (Trent 700 at SAS)
  • Classic, small winglets
  • Listed as A333 on trackers

Several operators fly under the SAS logo. For passengers that is barely visible, for spotters it is the core of a clean identification.

Operator Base Registration Type Special feature
SAS (main company) Sweden OY-, SE-, LN- A319 to A350 ICAO SAS
SAS Connect Ireland EI- A320neo ICAO SZS, founded in 2017 as SAS Ireland
SAS Link Sweden SE- Embraer E195 Founded in 2021, operating since 2022
Wet-lease partners various depends on the partner CRJ900, ATR 72-600 Fly in SAS colors with their own crews

The registrations of the main fleet are a legacy of the founding: SAS registers aircraft in all three countries. An OY- on the fuselage stands for Denmark, SE- for Sweden, LN- for Norway. At SAS Connect you find the Irish EI-. How country prefixes work is explained in the article on country codes on aircraft; how to read a complete registration is covered in Understanding aircraft registrations.

On regional routes, SAS has relied on rented aircraft with crews for years. The CRJ900 with its rear-mounted engines and the ATR 72-600 with propellers are part of that. Exactly which partners they are has changed several times. What is behind the model is explained in the article Wet lease explained.

Check the tail

Blue with the white SAS logo – that settles the brand.

Identify the type

Airbus, Embraer, CRJ or ATR? The type already narrows down the operator considerably.

Read the registration

OY-, SE-, LN- or EI-: the prefix shows the country of registration and the likely company.

Check the tracker

The ICAO code confirms who is really operating the SK flight.

How to recognize SAS

SAS unveiled its current livery in September 2019 and first applied it to new A350s and A320neos. Typical features are a light fuselage with a large, silver “SAS” title up front and a blue tail with a white logo, whose blue extends into the rear fuselage. The engines carry the “Scandinavian” title in blue – and the same title appears in large letters on the underside of the fuselage. When one passes directly overhead, that is one of the best identifying features.

Then there are the Viking names: SAS traditionally christens its aircraft with names that include “Viking.” In May 2026, for example, an A350-900 – the newest, according to SAS – received the name “Frederik Viking,” in honor of the Danish king Frederik X. The name is on the fuselage and is worth noting in your logbook, because it identifies the aircraft unambiguously in addition to the registration.

For its 80th anniversary, SAS painted an A330-300 entirely in SAS blue in 2026, with a reinterpreted Scandinavian flag as a nod to the livery of the 1980s. Special liveries like this are sought-after subjects – how to track them down is shown in the guide to special liveries.

Watch out for mix-ups

CRJ900s and ATR 72-600s in SAS colors are not operated by SAS itself. So always photograph the registration too – that is the only way to assign the sighting to the right operator later.

Spotting SAS: Scandinavia and Germany

You see the most SAS aircraft at once at the three hubs. In Copenhagen, the Flyvergrillen is the best-known spot – there you meet SAS Airbuses, E195s and regional aircraft every few minutes. Stockholm Arlanda and Oslo also offer plenty of SAS traffic, along with the Scandinavian competition from Norwegian and, in Norwegian regional traffic, Widerøe.

In Germany SAS connects major airports with the Scandinavian hubs. Typical are European routes with the A320neo, and on weaker connections smaller types too. Since the alliance switch the offering has been in flux: the former close tie to Lufthansa is gone, and the cooperation with Air France and KLM is gaining weight. So check the current schedule before you go spotting instead of relying on older reports.

Good starting points for SAS in Germany are the observation deck at Hamburg Airport, the Zeppelinheim viewing platform in Frankfurt and the visitors’ hill in Munich. For a comparison within Northern Europe, also take a look at Finnair, which as a oneworld member serves a similarly Nordic network.

Good chances of SAS if …

  • you are spotting in Copenhagen, Stockholm or Oslo
  • your airport’s schedule lists SK flights to Scandinavia
  • you time the arrival and departure waves at the hub on the tracker

Check first if …

  • you are planning based on reports from the Star Alliance era
  • you are looking for a specific long-haul aircraft – A350s and A330s fly mainly from Scandinavia

Probably not a SAS day if …

  • your airport has no connection to Copenhagen, Stockholm or Oslo

Before you take up a spot, check the runway direction in use – otherwise you wait on the wrong side of the airport. How that works is explained in the guide to the runway direction in use at the airport. If you are new, Plane spotting for beginners helps you get started.

Safety and rules

Only take photos from publicly accessible areas. Fences, barriers and security areas are off limits, and drones have no business near airports. What applies legally is explained in the article Is plane spotting allowed?.

Common mix-ups

  • Still thinking of SAS as a Star Alliance member – since September 1, 2024, SAS has belonged to SkyTeam.
  • Attributing every SAS livery to the main company – SAS Connect, SAS Link and wet-lease partners fly in the same look.
  • Taking an EI- registration for a mistake – SAS Connect’s A320neos are registered in Ireland.
  • Mixing up the A320 and A320neo – the neo has clearly larger engines with thicker nacelles.
  • Treating the A330-300 and A330-900 as the same – engines and wingtips distinguish the generations.
  • Thinking SAS is just a Swedish airline – historically it belongs jointly to Denmark, Norway and Sweden, with registrations from all three countries.

Keep an eye on SAS

Conclusion

SAS is an airline with three home countries, three hubs and – since 2024 – a new alliance. Behind the uniform blue look are the main company, the Irish SAS Connect, SAS Link with its Embraers and rented regional aircraft. If you note type, registration and ICAO code together, you can assign every sighting with confidence – and with the Viking name you get one more detail for the logbook.

In short

SAS (IATA SK, ICAO SAS) is the Scandinavian network carrier with hubs in Copenhagen, Stockholm and Oslo and, since 2024, a member of SkyTeam. The blue tail shows the brand, the registration shows who is really flying.

Summary

  • You recognize SAS by the blue tail with the white logo and the large “Scandinavian” title on the underside of the fuselage.
  • The registration tells you the country: OY-, SE- and LN- belong to the main fleet, EI- to SAS Connect.
  • Not every aircraft with an SK flight number is a SAS Airbus: SAS Link with the E195 and wet-lease partners with the CRJ900 and ATR 72-600 fly too.
  • Since the move to SkyTeam, SAS has been closely tied to Air France and KLM – no longer to Lufthansa.

Frequently asked questions

What are SAS’s IATA and ICAO codes?

SAS’s IATA code is SK and its ICAO code is SAS. On the radio the crew uses the callsign “SCANDINAVIAN.” The subsidiary SAS Connect uses its own ICAO code SZS but also flies under SK flight numbers.

Which alliance does SAS belong to?

Since September 1, 2024, SAS has belonged to SkyTeam. Before that it was one of the founding members of Star Alliance in 1997 – together with Lufthansa, United, Air Canada and Thai. The trigger was the entry of Air France-KLM, whose airlines Air France and KLM belong to SkyTeam.

Is SAS part of Air France-KLM?

Partly. Since the end of the restructuring, Air France-KLM has held 19.9% of SAS and announced in July 2025 that it would raise its stake to 60.5%. That would make SAS a subsidiary of the group. Completion needs approval from the competition authorities; Air France-KLM most recently named the second half of 2026 as its target. Check the two companies’ announcements for the current status.

Which aircraft does SAS fly?

On short- and medium-haul routes mainly the Airbus A320neo, plus a few A321LRs, A319s and A320s. On long-haul routes it flies the A350-900 and A330-300. SAS Link operates Embraer E195s, and partners fly CRJ900s and ATR 72-600s on a wet-lease basis. On order are 45 Embraer E195-E2s; in June 2026 SAS also announced up to 40 Airbus widebodies of the types A330-900 and A330-300.

Does SAS still fly the Boeing 737?

Not in regular scheduled service anymore – SAS replaced the 737 with Airbus. One exception is a converted Boeing 737-700 for air ambulance flights that SAS operates for the Norwegian armed forces; the cooperation was extended in March 2026. According to SAS it has room for 18 stretchers, three of them for intensive care patients.

What are SAS Connect and SAS Link?

SAS Connect is an Irish subsidiary based in Dublin, founded in 2017 as SAS Ireland. It flies A320neos with Irish EI- registrations. SAS Link was founded in 2021, is registered in Sweden and flies Embraer E195s with 122 seats. Both look like SAS and carry SK flight numbers.

Why are SAS aircraft called “Viking”?

SAS traditionally names its aircraft after Vikings – a nod to its Scandinavian roots. The names are on the fuselage. In May 2026, for example, SAS christened an A350-900 – its newest, according to SAS – “Frederik Viking,” in honor of the Danish king Frederik X.

Where can I spot SAS?

You see the most SAS traffic at the hubs Copenhagen, Stockholm Arlanda and Oslo. In Copenhagen the Flyvergrillen spot is a classic. In Germany SAS serves major airports with connections to Scandinavia; which routes are currently scheduled is best checked in the current schedule of your airport.
