Sobelair

If you flew on vacation from Belgium between the 1970s and the early 2000s, you may well have boarded an aircraft with “Sobelair” on the fuselage. The Brussels airline was the leisure subsidiary of the flag carrier Sabena – and it outlived its parent by just over two years. Here you will learn how Sobelair began with flower cargo and Congo flights, which aircraft defined it, and how to recognize it on old photos.

Sobelair at a glance

Sobelair was a Belgian charter airline based at Brussels-Zaventem Airport. It was founded on July 30, 1946 under the name Société d’Étude et de Transports Aériens, SETA for short. The later name Sobelair is an abbreviation from French and stands for a “Belgian air transport company” – sources give the exact spelling of the full name in different ways.

The first commercial flight on October 15, 1946 was anything but a vacation flight: a Douglas DC-3 carried flowers via Paris to Nice. As early as 1947, flights from Brussels to Elisabethville in what was then the Belgian Congo were added, on behalf of companies operating in the colony. These companies were also the most important shareholders at first.

In 1949, the Belgian flag carrier Sabena took the majority. That began a relationship that shaped Sobelair for more than five decades – in routes, aircraft and even livery.

Codes and callsign

• IATA code Q7: appeared in flight numbers, timetables and on tickets.
• ICAO code SLR: the identifier used with air traffic control.
• Callsign SOBELAIR: how crews identified themselves on the radio – simply the company name.

If you are going through old timetables or boarding passes, knowing the two code systems helps: the two-character IATA code is what passengers see in the flight number, the three-letter ICAO code is for air traffic control. How exactly this fits together is explained in the article on IATA and ICAO codes. You can read more about the stories behind radio callsigns in Airline callsigns and their history.

The history in stages

From Congo services to leisure airline

Sobelair’s first years had nothing to do with package vacations. The airline flew cargo and personnel back and forth between Brussels and Central Africa for companies active in the Belgian Congo. From 1947, it connected Brussels with Elisabethville, today’s Lubumbashi. For these long routes with intermediate stops, Sobelair relied on the four-engine Douglas DC-4, which was among the standard aircraft in long-distance traffic in the postwar period.

The Congo’s independence in 1960 changed everything. The most important market fell away, and Sobelair had to reinvent itself. The solution lay in growing vacation traffic: more and more Belgians wanted to go to the Mediterranean, and tour operators were looking for seats. From 1961, the Douglas DC-6 flew for this purpose. The difference between a charter vacation flight and classic scheduled service is explained in the article Charter vs. scheduled flights.

At the same time, the division of labor with Sabena became closer. The flag carrier handed Sobelair routes that were not worthwhile for it – in 1967, for example, connections to Amsterdam, Cologne and Stuttgart. For the subsidiary, that meant a base load; for the parent, a convenient way to save costs.

The fleet: from the DC-3 to the 767

Over its history, Sobelair took on many second-hand aircraft, often directly from Sabena. The overview is based on common reference works, which themselves point out that the fleet list is not complete.

Type	Period at Sobelair	Use	Spotter tip
Douglas DC-3	from 1946	First flights, cargo	Twin-engine classic of the postwar era
Douglas DC-4	1947–1961	Flights to the Belgian Congo	Four-engine piston long-haul aircraft
Cessna 310	1957–1961	Domestic flights in the Congo	Small twin-engine aircraft
Douglas DC-6	1961–1970	Vacation flights to the Mediterranean	Pressurized cabin, larger than the DC-4
Fokker F27	1968–1971	Short-haul	Turboprop with a high-wing layout
Sud Aviation Caravelle	1971–1978	The airline’s first jet	Rear-mounted engines, triangular windows
Boeing 707	1974–late 1980s	Medium- and long-haul	Four engines under the wing
Boeing 737-200	1978–1997	Backbone of the leisure fleet	Slim engines of the first 737 generation
Boeing 737-300/-400	1987/1990–2004	Short- and medium-haul	In service until the end
Airbus A300B4	1993–1999	Extra capacity	Twinjet widebody, in service for only a few years
Boeing 767-300ER	1994–2004	Long-haul, including the Caribbean	The flagship until the end
Boeing 737-800	2002–2004	Short- and medium-haul	Brief appearance, two aircraft at the end

In addition, the lists include types that Sobelair used only very briefly: a DC-10-30 and an MD-83 in 1994, a Boeing 727 in the mid-1990s and an Airbus A320 that was briefly leased in 2000 from the Irish charter airline TransAer. At the end, according to the available fleet lists, the fleet consisted of three 737-300s, four 737-400s, two 737-800s and five 767-300ERs.

Caravelle: the first jet

With the Sud Aviation Caravelle, Sobelair entered the jet age in 1971. The aircraft came second-hand from Sabena, which fit the close tie to the parent. The French Caravelle, with its rear-mounted engines and characteristic triangular windows, was one of the most elegant short-haul aircraft in Europe at the time. It stayed in service until 1978.

Boeing 707: four-engine jet for far-off destinations

From 1974, the Boeing 707 joined the fleet. With it, Sobelair could reach vacation destinations that were too far for the Caravelle. At the end of the 1980s, the last 707 left the airline. How the 707 changed air travel is covered in the article on the history of the Boeing 707.

Boeing 737: three generations in one airline

From 1978, the Boeing 737 defined the picture. First came the Boeing 737-200, in service until 1997. From 1987, the Boeing 737-300 joined, and from 1990 the longer Boeing 737-400. Shortly before the end, two examples of the Boeing 737-800 even flew for Sobelair – so the airline had used three 737 generations over the course of its history.

Boeing 767-300ER: back to long-haul

In 1994, Sobelair put its first Boeing 767-300ER into service and thus flew long-haul again, including to the Caribbean. Around the year 2000, the long-haul program included destinations in Cuba, the Dominican Republic, Mexico, the Netherlands Antilles and the USA. Until the end, the 767 was the largest aircraft in the fleet. The manufacturer of all the late types was Boeing.

Partners and customers in the 1990s

By the 1990s, Sobelair had long been a pure leisure and charter airline. Its most important customer became the Belgian tour operator Jetair, with which it signed a charter contract in the late 1990s. The model was the same as at other European leisure airlines: the operator sold package holidays, and the airline provided the seats.

At the same time, Sobelair benefited from the link between Sabena and Swissair. After Swissair took a stake in Sabena, cooperation in the charter business was sought. Talks with a Swiss charter company failed; instead, an agreement with Crossair came about. In 1997, Sobelair flew charters from Zurich to San Francisco and Las Vegas on behalf of Swissair, and in 2001 agreements followed with the Antilles airline ALM and with the Swiss charter airline Balair.

You will find a similar interplay of airline and travel group at Britannia Airways, the house airline of the British operator Thomson. Unlike Britannia, though, Sobelair did not have a travel group behind it as owner but a flag carrier – and that is exactly what proved its undoing.

How to recognize Sobelair

On historical photos, Sobelair is usually quick to identify. The “Sobelair” titles were on the fuselage, and for many years the livery clearly followed Sabena’s – right down to the “S” on the tail that the Caravelles already wore. Toward the end of its history, the fleet received a corporate livery of its own. Because the details changed several times over the decades, it is best to compare individual variants against dated photos. How airlines change their look and why transitional liveries arise is shown in the article When airlines change their design.

Accidents

The airline’s only fatal accident occurred on April 22, 1960. A Douglas C-54 Skymaster, the military version of the DC-4, registered OO-SBL, was on a charter flight from Cairo and crashed into a mountainside on approach to Bunia in the Belgian Congo. All 35 people on board were killed.

On December 20, 1970, a DC-6 on cargo duty (OO-CTL) had to make an emergency landing in Málaga in bad weather. Because of a hydraulic fault, the left main landing gear could not be extended, and the aircraft ran off the runway and was a total loss afterward. On March 29, 1981, an engine of a Boeing 707 (OO-SJA) caught fire shortly after takeoff in Brussels. The crew returned with no time to dump fuel and deliberately steered the overweight aircraft off the runway – the aircraft was badly damaged, and all 117 people on board survived.

The end: from Sabena’s collapse to bankruptcy

Fall 2001 hit Sobelair twice. First Swissair went into crisis, then Sabena collapsed in November 2001 as well. The subsidiary suddenly stood without a parent. Several rescue ideas circulated: the regional airline Delta Air Transport briefly considered taking over the 767, but instead the airline Birdy Airlines emerged for scheduled flights to Africa. Talks with the German travel group Preussag, later the TUI group, ended without result in February 2002.

In June 2002, an investor group around the entrepreneur Aldo Vastapane took over the airline. Sobelair restarted, including with scheduled flights from Brussels to Johannesburg. The financial situation did not improve, however: the Johannesburg route was discontinued again at the end of June 2003, several important customers were lost in 2003, and flights on behalf of a Caribbean airline brought losses. A takeover offer from Jetair, the most important customer, was not concluded.

In early January 2004, Sobelair applied for creditor protection. On January 19, 2004, the Brussels commercial court declared the airline insolvent, and around 450 employees lost their jobs. The legal aftermath is curious: in summer 2004, an appeals court overturned the bankruptcy declaration, and at the end of 2005 Belgium’s highest court confirmed that decision. Sobelair never flew again anyway – the company was wound up. The article on airline collapses in Europe gives an overview of similar cases.

The successor: Jetairfly and TUI fly Belgium

Jetair bet on a house airline of its own: Jetairfly, founded in November 2003 as TUI Airlines Belgium. Initially, only two aircraft were planned. Because Sobelair dropped out, the new airline started with five Boeing 737-400s. Today this airline flies as TUI fly Belgium and belongs to the TUI airlines. It is not a legal successor of Sobelair – but it took over its role in Belgian leisure flying.

A new landscape also emerged on the scheduled side after 2001: SN Brussels Airlines arose from the remains of Sabena, and Sobelair still flew charters for it in 2003. After the merger with Virgin Express, it became today’s Brussels Airlines. You can find the story of the Belgian low-cost competitor at Virgin Express.

Common mix-ups

• Equating Sobelair with Sabena – Sobelair was an independent subsidiary with its own codes, even if the livery was similar.
• Taking TUI fly Belgium for a renamed Sobelair – it is a new company that took over Sobelair’s role.
• Confusing Sobelair with Belair – despite the similar sound, Belair was a Swiss leisure airline and had nothing to do with Sobelair.
• Dating the end to 2001 – Sabena ended in 2001, but Sobelair flew until January 2004.
• Treating the DC-4 and the C-54 as different types – the C-54 Skymaster is the military version of the same design.

Conclusion

For almost 58 years, Sobelair was a fixture of Belgian aviation. It began with flower cargo and Congo flights, became a leisure airline after 1960 and at the end flew a modern Boeing fleet of 737s and 767s. The close tie to Sabena long gave it stability and aircraft – and took away its footing when its parent ended. For spotters, Sobelair is now a chapter of aviation history that you can find again on old photos from Zaventem and the vacation airports of southern Europe.
