South Africa’s aviation network is facing fresh turbulence this week as a confluence of air traffic control constraints, adverse weather, and regional flooding triggers a wave of flight disruptions. At least 25 flights have been canceled and many more delayed across key carriers including SunExpress, CemAir, South African Airlink and other operators, affecting major gateways in Johannesburg and Cape Town as well as the safari hub of Hoedspruit.

The cascading operational issues are stranding passengers, complicating tourism flows, and testing the resilience of airlines and airports at the height of the southern summer travel period.

Multiple Airlines Hit as Operational Pressures Mount

The latest round of disruptions has not been confined to a single airline or route, underscoring broader stresses in the regional aviation system. While South African Airlink has been among the most visibly affected carriers, low cost and regional airlines such as CemAir and SunExpress have also seen schedules squeezed on key domestic corridors between Cape Town, Johannesburg and secondary destinations.

Recent operational data and airline updates show a pattern of cancellations and extensive delays concentrated on high-demand trunk routes, including Cape Town to Johannesburg services and connections into safari and leisure destinations such as Hoedspruit. Airlines that only recently expanded or relaunched routes in and out of South Africa are now being forced to trim or reshuffle schedules, leaving travelers uncertain about same-day connections and onward plans.

For SunExpress and CemAir, whose South African operations rely heavily on smooth turnarounds and coordinated slot timings at busy airports, the disruption comes just as carriers had been gearing up to capture peak-season leisure demand. The interruptions are spilling beyond individual flights, as crew rotations, fleet utilization and ground operations all come under strain.

Johannesburg OR Tambo Struggles With Air Traffic Control Constraints

At Johannesburg’s OR Tambo International Airport, South African Airlink has publicly warned customers about delays linked to air traffic management. In a notice issued in early January, the airline cited air traffic control staffing shortages and the suspension or expiry of some instrument flight procedures, which are used to guide aircraft safely in and out of busy airspace.

According to the airline, these constraints have resulted in departure delays, airspace restrictions and even occasional diversions, creating knock-on effects across its domestic and regional network. With OR Tambo serving as a central hub for national and regional connections, any constraint at Johannesburg quickly ripples into Cape Town, Durban and smaller destinations such as Hoedspruit and other safari gateways.

While the number of outright cancellations at OR Tambo has so far been lower than the tally of delayed services, the congestion has forced airlines to pad schedules, hold aircraft on the ground longer than planned, and rebook passengers whose connections have become untenable. For business travelers and tourists alike, this has meant longer dwell times in terminal buildings and increased pressure on airline call centers and airport service desks.

Cape Town International Sees Knock-on Delays and Select Cancellations

Cape Town International Airport, South Africa’s primary leisure gateway, has mirrored some of the challenges seen in Johannesburg, though with its own local triggers. Historical patterns at secondary airports such as George have highlighted how the suspension of flight procedures in poor weather can cause widespread cancellations and indefinite delays for airlines such as Airlink and CemAir. Similar dynamics are playing out at Cape Town now that air traffic constraints and weather variability intersect during the busy holiday period.

Operational tracking of individual flights reveals a patchwork of disruptions. Some SunExpress services linking Cape Town and Johannesburg earlier in the season have been pulled from current schedules, while other routes once operated by CemAir have seen service gaps and irregular frequencies. Even when flights are not formally canceled, departures and arrivals often slide beyond their published times, forcing travelers to adjust onward itineraries at short notice.

For leisure travelers using Cape Town as a springboard to safari regions or the Garden Route, the reliability of domestic connections is a crucial part of trip planning. The current delays and selective cancellations are prompting some tour operators and travel advisors to recommend longer buffers between domestic legs, extra nights in Cape Town or Johannesburg, and fully flexible booking options where possible.

The most dramatic disruption has emerged at Hoedspruit, a critical gateway for tourism into the Kruger National Park and surrounding private reserves. On 14 January, South African Airlink confirmed the suspension of all flights to and from Hoedspruit due to severe flooding in Limpopo province. The floods have rendered roads impassable and severed access between the airport and major lodges, communities and park entrances.

The suspension covers a full slate of daily services between Hoedspruit and both Cape Town and Johannesburg, including multiple Airlink flight pairs that typically ferry safari guests in and out of the region. With the airport temporarily inaccessible by road, the airline has said operations will only resume once authorities declare it safe and infrastructure connections have been restored.

The shutdown of scheduled services into Hoedspruit delivers a significant blow to regional tourism just as international and domestic demand peaks for wildlife experiences. Lodges that rely on predictable air links for same-day guest turnarounds now face logistical challenges in relocating or accommodating travelers whose flights never depart. Some passengers already in the bush are having to extend their stays, arrange costlier charter or road transfers where feasible, or reroute entirely via alternative gateways such as Skukuza or Nelspruit.

Tourism and Passenger Experience Under Growing Pressure

For South Africa’s tourism sector, the timing of these disruptions could hardly be worse. January sits within the prime southern summer season, when domestic holidaymakers and international visitors converge on cities such as Cape Town and Johannesburg before heading onward to safari, wine, or coastal destinations. Even a modest percentage of cancellations and extended delays can have outsized effects when flights run close to capacity and accommodation is heavily booked.

Travel agents and tour operators report spending long hours reworking itineraries, securing backup hotel nights, and juggling transfer arrangements. Safaris that once dovetailed neatly with domestic flights now risk starting a day late or ending a day early due to gaps in the air schedule. Families traveling with children, as well as older visitors, are particularly vulnerable to the stress of overnight delays or extended waits in busy terminals.

Within airports, passengers are experiencing the familiar ripple effects of disruption: longer queues at check-in and security, high demand at airline help desks, and pressure on food and seating infrastructure. Airline staff, already working close to capacity, are handling rebookings while attempting to keep remaining flights operating safely and on time. While most carriers are offering waivers or free date changes in clearly disrupted markets such as Hoedspruit, the wider pattern of rolling delays at Johannesburg and Cape Town is more complex to navigate.

Airlines Balance Safety, Regulation and Commercial Realities

Airlines operating within South Africa face a delicate balancing act between maintaining commercially viable schedules and meeting stringent safety and regulatory requirements. In the case of Airlink, the carrier has emphasized that it is fully compliant with aviation regulations even as it communicates customer notices about delays stemming from air traffic control and procedure issues. The airline has pointed to factors largely outside its direct control, including the management of instrument approaches and staffing within air navigation services.

CemAir, which has been expanding its regional footprint and preparing to launch a new direct route between George and Hoedspruit later in 2026, now finds itself planning growth amid a backdrop of infrastructure and regulatory constraints that periodically choke access to smaller airports. Routes that promise to streamline multi-destination itineraries, such as direct George to Hoedspruit links, also depend heavily on resilient air traffic services, navigational procedures and weather-resilient airport operations.

SunExpress and other carriers with seasonal or limited rotations in the South African market are contending with the inherent vulnerability of sparse schedules. When only a few weekly flights are offered on a route, a single cancellation or operational gap can strand customers for days rather than hours. For these airlines, decisions about whether to consolidate flights, reroute aircraft or temporarily suspend services must weigh both immediate operational risks and long-term brand perception among leisure travelers.

Travelers Adjust Strategies Amid Ongoing Uncertainty

For passengers caught in the middle of the latest disruptions, practical strategies are evolving rapidly. Travel advisors and frequent flyers are increasingly recommending that visitors build additional slack into their itineraries, especially when connecting from domestic flights in Johannesburg or Cape Town to international long haul services. Leaving a longer gap between arrival and departure, or overnighting in a gateway city before flying onward, can help reduce the risk of missed international connections.

Travelers heading to remote or safari destinations such as Hoedspruit are being encouraged to stay closely informed through airline apps, airport information screens and direct communication with lodges. In some cases, properties in the Kruger region are assisting guests with alternative transfers or adjusting stay dates to accommodate flight suspensions. Where floods and infrastructure damage are involved, travel insurance policies and flexible booking conditions are becoming crucial tools for recouping costs.

For domestic business travelers, the lesson from this week’s events is similarly clear. Same day return trips that rely on tight turnarounds at OR Tambo or Cape Town International are riskier in periods of known air traffic control or weather pressure. Many corporate travel managers are advising employees to consider earlier departures, later returns, or overnight stays when critical meetings and events are involved, particularly on routes served primarily by smaller regional carriers.

What to Watch in the Coming Days

The trajectory of South Africa’s current wave of air travel disruptions will hinge on several moving parts in the days ahead. Weather patterns in Limpopo and surrounding regions will determine how quickly floodwaters recede and access roads to Hoedspruit Airport can be safely reopened. Only once those links are restored can scheduled Airlink services resume, allowing the safari tourism pipeline to flow more freely again.

In Johannesburg, the effectiveness of efforts to manage air traffic control staffing and reinstate or replace suspended instrument procedures will be central to stabilizing departure and arrival flows at OR Tambo. Any improvement there is likely to benefit airlines such as Airlink, CemAir, SunExpress and others that depend on Johannesburg as a coordination point for national and regional schedules.

At Cape Town International, where demand remains robust and airlines are keen to protect their peak-season revenues, carriers will be watching closely for signs that the current wave of delays is easing rather than intensifying. If air traffic pressures in Johannesburg abate and weather conditions remain stable along the coast, there is room for a gradual return to more predictable operations. Until then, South Africa’s skies are likely to remain challenging terrain for airlines and passengers alike, with flexibility and real-time information serving as essential companions for anyone planning to fly.
