African aviation hubs are becoming increasingly interconnected due to expanded airline routes and airport investments aimed at increasing capacity to handle growing passenger traffic. Johannesburg and Addis Ababa are at the center of this race to create hubs capable of connecting more African cities with global markets.
According to the OAG Megahubs 2026 report, Johannesburg's OR Tambo International Airport ranks 40th globally, while Addis Ababa Bole International Airport is among the top 50 most connected airports worldwide. Johannesburg has dropped from 38th in 2025, whereas Addis Ababa has risen from 60th.
These two airports are the only representatives of Africa in the global Top 50. This ranking includes 12 European airports, 3 Middle Eastern airports, 16 Asian airports, 1 Australian airport, 11 US airports, and 1 Canadian airport, in addition to the two African centers.
Rankings
OAG, which compiles this ranking, explains that the ranking is determined by comparing the number of planned international flight connections, both arriving and departing, with the number of destinations served by the airport on the busiest day of the year. The analysis covered the 100 largest airports and the 100 largest international airports by planned seats for the 12 months leading up to August 2026, using August 2nd as the busiest day.
In Johannesburg, Airlink operates 35% of flights, providing the airport with a more even distribution of airlines. In Addis Ababa, Ethiopian Airlines operates 94% of flights, making it one of the most concentrated large hubs globally, according to OAG. This difference reflects two distinct hub models: Johannesburg attracts traffic from multiple airlines and regional networks, while Addis Ababa is built around Ethiopian Airlines and its expanding network of long-haul and African flights.
In OAG's ranking for the Middle East and Africa, Johannesburg ranks second after Dubai, and Addis Ababa ranks fifth. The regional Top 10 is completed by Cairo, Abu Dhabi, Jeddah, Casablanca, and Sharjah. Thus, Johannesburg is recognized as the leading African airport in terms of connectivity, while Addis Ababa is the second African representative.
Capacity figures demonstrate why the competition is becoming increasingly significant. According to OAG, in September 2026, African and international carriers serving the continent planned 25.8 million seats, an increase of 9.4% compared to the previous year. International services accounted for 78% of this capacity. In September, Cairo was Africa's largest airport by planned seats with 1.79 million, followed by Addis Ababa with 1.19 million and Johannesburg with 1.16 million, according to OAG. Addis Ababa's capacity increased by 6.5% year-on-year, and Johannesburg's by 5.0%.
The greatest pressure is observed in Addis Ababa, where Bole International Airport is approaching the limits of its expanded capacity. According to the Ethiopian government, Bole is close to reaching an expanded capacity of 25 million passengers per year. Ethiopian Airlines reports that in the fiscal year ending June 2025, the airport handled 19 million passengers, whereas earlier forecasts suggested the facility could reach its limit as the airline's global network expands. In response, Bishoftu International Airport, located about 40 kilometers southeast of Addis Ababa, is being considered.
Construction
The construction of the new airport officially began on January 10, 2026, when Prime Minister Abiy Ahmed laid the cornerstone. According to Ethiopian Airlines, the first phase is designed to serve 60 million passengers annually by 2030, and the full master plan anticipates accommodating 110 million passengers, four runways, and parking for 270 aircraft. The estimated cost of the first phase is 12.5 billion US dollars.
According to Zaha Hadid Architects, who designed the terminal, it is expected that up to 80% of passengers will transfer between flights without leaving the airport. The terminal design utilizes a central spine inspired by the Great Rift Valley to reduce transfer distances. The airport's location also offers an operational advantage. According to project documentation, Bishoftu is situated at an altitude of approximately 1,910 meters above sea level, nearly 400 meters lower than Bole. Longer runways should improve aircraft performance and allow Ethiopian Airlines to carry more passengers and cargo on long-haul routes.
Ethiopian Airlines is already expanding the network that will feed this hub. The airline announced the launch of daily direct flights between Durban and Addis Ababa starting December 11, 2026. Additionally, four weekly flights between Addis Ababa and Port Harcourt will begin on December 1, making the Nigerian city the fifth destination in the country. The airline has also expanded its European and African network, adding flights to Geneva and Lyon, Port Louis, Nakala, and Gizan, thereby increasing the number of routes that can funnel traffic through Addis Ababa.
Johannesburg follows a different approach. Instead of building a new hub, OR Tambo International Airport is investing in existing infrastructure. According to Airports Company South Africa, OR Tambo is implementing a five-year capital plan worth 14.5 billion Rand (approximately 884 million US dollars) to modernize the airport and enhance its operational reliability. The current phase includes updating escalators and tuggers, new furniture, improved navigation, and replacing carpets with durable tiles at international gates.
The longer-term program includes a mid-field cargo terminal project valued at 5.7 billion Rand (approximately 348 million US dollars), new cargo infrastructure, and plans for a mid-field passenger terminal. According to ACSA's corporate plan, the mid-field cargo terminal project is scheduled for completion in the 2029/30 fiscal year, while other projects are planned for 2031 and beyond. Johannesburg's position is supported by a large and established network. According to OAG, OR Tambo offers connections to all six inhabited continents. The airport has also remained among the largest in Africa in terms of planned capacity in 2026.
These investments come against a backdrop of continued demand growth across the continent. According to IATA's 2026 forecast, African passenger traffic is expected to grow by 6.0% in 2026, outpacing the global forecast of 4.9%. In a June forecast, IATA later projected that traffic growth in Africa would reach 10.0% in 2026, as airlines benefit from shifts in global travel patterns, particularly due to disruptions in traffic patterns around the Middle East.
Parallel to the growth, capacity is also expanding. According to OAG, airlines serving African markets planned 25.8 million seats in September 2026, an increase of 9.4% compared to the previous year.
Growth
However, growth remains constrained by the operating economy in Africa. According to IATA, African airlines are projected to earn about $200 million in net profit in 2026, equivalent to approximately $1.30 per passenger, compared to the global average of $7.90. IATA also notes that Africa accounted for 79% of the $1.2 billion in global aviation funds locked up as of October 2025, leaving about $954 million trapped in African markets.
The continent's traffic is now also heavily linked to markets outside Africa. According to OAG, Europe provided more than half of the planned international seats in Africa in August 2026, making European hubs such as London Heathrow, Amsterdam, and Frankfurt important connection points for African airlines and passengers.
African airlines are growing from a relatively small base. According to the African Airlines Association, its 50 members transport over 85% of international traffic among African carriers. Passenger traffic is projected to reach 137.3 million in 2026, a 21.5% increase from 2025.
