Johannesburg O. R. Tambo Airport

The first time you step off a plane in Johannesburg, you notice it quickly: the air is thinner, the sun stronger and the light clearer than at almost any European airport. O. R. Tambo sits at about 1,700 meters on the South African Highveld and has been the most important gateway to southern Africa for decades. For spotters, that means plenty of airlines and registrations you never see at home, two long runways with a clear division of labor – and a few rules you have to take more seriously here than at the visitors’ hill in Munich.

From Jan Smuts Airport to O. R. Tambo

The story begins in the 1940s. A government report at the time recommended a large international airport for the Witwatersrand, the industrial and mining center around Johannesburg. A site south of the city was out of the question because gold-bearing rock lay beneath it – instead, the airport was built in Kempton Park in the northeast. On September 1, 1953, the airport went into operation as Jan Smuts International Airport, with the official opening following a month later. Among the first customers were BOAC, Air France, KLM, Qantas and South African Airways.

With the jet age, the airport grew strongly in the 1960s and 1970s. South African Airways brought the first Boeing 747s to Johannesburg from 1971, and in the 1970s even the Concorde tested its behavior here under “hot and high” conditions. The 1980s, on the other hand, were marked by sanctions against the apartheid regime: many foreign airlines withdrew, and SAA was no longer allowed to overfly most African countries. On the route to Europe, the especially long-range Boeing 747SP was therefore used, flying a wide arc over the Atlantic.

After the end of apartheid, many things changed at once. In 1994 the airport was renamed Johannesburg International Airport, in the mid-1990s the newly founded Airports Company South Africa (ACSA) took over operations, and in 1996 Johannesburg overtook Cairo as the busiest airport on the continent. Since October 27, 2006, it has borne the name of Oliver Reginald Tambo, one of the leading minds of the ANC in the fight against apartheid. The ICAO code only followed in 2013, changing from FAJS to FAOR.

Largest airport in Africa – is that still true?

The question is justified because the answer differs depending on the source. Operator ACSA still describes O. R. Tambo as the largest and busiest airport in Africa, and for more than two decades that was undisputed in terms of passenger numbers. Before the pandemic, Johannesburg counted a good 21 million passengers a year, then traffic collapsed massively in 2020.

Since then, traffic has recovered considerably and stood at a good 20 million passengers in fiscal year 2025/26. Several analyses, however, now see Cairo Airport back in front in passenger numbers. What is undisputed: for southern Africa, Johannesburg is the most important hub, and according to ACSA, more than half of all air passengers in South Africa pass through O. R. Tambo.

Hot and high: what elevation does to aircraft

Johannesburg is a textbook example of a “hot and high” airport. At about 1,700 meters, the air is considerably thinner than at sea level, and on warm summer days the density drops further. For an aircraft, that means less lift on the wings and less thrust from the engines. The result: longer takeoff rolls, shallower climbs and, for heavy long-haul aircraft, sometimes restrictions on cargo or fuel.

That’s why the runways are so long. 03L/21R measures about 4.4 kilometers, making it one of the longest commercial runways in the world, while the parallel 03R/21L comes in at about 3.4 kilometers. For you as a spotter, that has a visible effect: fully loaded widebodies often lift off late and climb more gradually than in Frankfurt or Amsterdam – which makes takeoffs on the long runway a subject of their own.

Two runways with a clear division of labor

Originally, the airport had one main runway and two shorter crosswind runways. The crosswind runways have long since become taxiways, and since the end of the 1980s there have been two parallel runways in a north-northeast to south-southwest direction. According to spotter guides, the split is fairly stable in everyday operations: the long western runway is mainly used for takeoffs, the eastern one predominantly for landings.

Which direction applies depends on the wind, as everywhere. With wind from northerly directions, aircraft take off and land toward 03; with wind from the south, toward 21. How to assess the runway direction in advance is explained in the post Understanding runway direction at airports. You can see it live fastest via flight tracking via ADS-B.

Who flies in Johannesburg

South African airlines shape the picture in the sky. FlySafair flies Boeing 737 jets such as the 737-800 in domestic traffic, while Airlink serves smaller cities in South Africa and many destinations in neighboring countries with Embraer regional jets – from the ERJ 135 to the E190. South African Airways, once one of the big names in long-haul, has only gradually put aircraft back into service after the shutdown in 2020; its aircraft with the national flag on the tail are correspondingly rarer than they used to be. Smaller operators such as LIFT and CemAir come on top of that.

It gets exciting with the airlines from the rest of Africa. Besides big network carriers like Ethiopian Airlines, Kenya Airways and EgyptAir, numerous smaller carriers fly to JNB – such as RwandAir, TAAG Angola Airlines, Air Mauritius and Air Tanzania, plus airlines from Botswana, Mozambique, Malawi, Zimbabwe, Zambia and Eswatini. Many of them have only small fleets. That has a side effect: during a stay of several days, you often see the same registrations more than once – so it pays to look specifically for the ones you’re still missing.

Long-haul from Europe, the Middle East and Asia

Johannesburg is also a classic long-haul destination. From Europe, Lufthansa flies from Frankfurt and Munich, British Airways and Virgin Atlantic from London Heathrow, and there are also KLM, Air France, Swiss, Condor and Turkish Airlines. The Gulf carriers Emirates, Qatar Airways and Etihad Airways link JNB with their hubs in Dubai, Doha and Abu Dhabi. Add connections to Asia with Cathay Pacific and Singapore Airlines, to Australia with Qantas and to the US with Delta and United.

Which types are used changes with schedule and season – from the Boeing 777-300ER through the Airbus A350-900 to the Boeing 787-9. The airport is equipped for the Airbus A380: four bridge positions at the International Pier are designed for the superjumbo, and the first A380 on African soil landed here as early as 2006. Many Europe connections are overnight flights that leave in the evening and arrive early in the morning. So check the arrival and departure boards to see when long-haul traffic is actually moving in daylight.

Cargo on the Highveld

Johannesburg is also South Africa’s most important cargo hub. On dedicated aprons stand freighters of airlines such as Cargolux, Lufthansa Cargo, Emirates SkyCargo, Qatar Airways Cargo, Turkish Cargo and Ethiopian Cargo, plus express services and African cargo airlines such as Astral Aviation. According to a spotter guide, after landing, freighters often taxi past a spot at a sports field on the Hotel taxiway. How to tell the different freighters apart is shown in the post Identifying freighter aircraft.

In the long term, ACSA plans a new cargo terminal and another passenger terminal between the two runways. When and in what form these projects will be implemented is open.

Terminals and getting there

The passenger area is compact. Terminal A serves international traffic, Terminal B domestic traffic; in between lies the Central Terminal Building, completed in 2009, which connects both areas. The Gautrain express train stops there and has connected the airport with Sandton, and from there with Johannesburg and Pretoria, since 2010. Part of the long-haul traffic is handled at the International Pier, which opened in 2009.

For the terminals, the Gautrain is enough. For the spots along the approach paths, however, you need a car: the distances are long, and there is practically no public transit that stops there. The road connection to Johannesburg runs via the R24 Airport Freeway.

Spotting in Johannesburg: locations at a glance

Spotter guides describe Johannesburg as one of the few airports in Africa where spotting is well known and tolerated. The most important locations can be roughly divided into three groups.

Observation decks at the terminal. Landside, Terminal B (domestic) has a large window front on the top level, which you reach by elevators from the atrium hall. In Terminal A (international), “Viewing Deck” signs lead to another viewing area. According to a spotter guide, the decks are free to access and work best from midday until the end of the day. Expect reflections and partly tinted glass, find a clean spot and ask on site whether all accesses are open.

Approaches to 03R. A well-known spot is the grounds of the Birchwood Hotel south of the airport. Spotter guides describe it as a safe location with restaurants and restrooms nearby; you have the best light from sunrise until about 10 a.m. However, trees have grown there that increasingly restrict the view, and access for non-guests is described inconsistently – spotter guides name an alternative roadside spot for that. There are further locations on meadows and roadsides, but some are remote.

Approaches to 21L. With a south wind, aircraft land from the north. Along Bonaero Road there are roadside spots for these landings, with morning or afternoon light depending on the location. Trees and roofs shorten the photo window there.

Light in the Southern Hemisphere

The biggest mental trap for European spotters in Johannesburg concerns the sun. In the Southern Hemisphere it travels across the north, so at midday it is in the north instead of the south. Familiar rules of thumb from Frankfurt or Munich work mirror-inverted here. On top of that comes the orientation of the runways in a north-northeast to south-southwest direction: in the morning the sun is in the east, so locations west of the approach path are shooting into the sun and eastern ones have the advantage – in the afternoon this reverses.

Climatically, the Highveld is a gift for photographers. The region has a great many sunny days, and in the dry southern winter between May and August the sky often stays cloudless for days. In the southern summer, by contrast, thunderstorms often form in the afternoon, which deliver spectacular clouds but make the light flip quickly. With the post Planning the sun position at the photo spot you can work out the right time.

Johannesburg compared

Compared with European hubs like Frankfurt Airport or London Heathrow, Johannesburg is smaller and much more regional in character. The appeal lies in the mix: Embraer jets from Botswana, domestic 737s and widebodies from Istanbul or the Gulf arrive on the same runway. Anyone who wants to understand African aviation combines JNB well with Cairo in the north – two hubs that have been contesting the top spot on the continent for decades.

If you’re planning the trip as part of a vacation, the posts Plane spotting on vacation and Spotting abroad help with equipment and the legal situation.

Conclusion

O. R. Tambo is not an airport where you arrive by suburban train and stand on a hill. In return, it offers something no European hub can deliver: the variety of aviation in southern Africa, framed by long-haul from Europe, the Middle East and Asia. Two long runways with a clear division of labor, strong light and the peculiarities of an airport at 1,700 meters make every visit something of its own.

Anyone who knows the runway direction, factors in the sun on the north side and takes the safety rules seriously comes home with a memory card full of registrations that nobody has in Europe.
