São Paulo airport disruption delays 107 flights and cancels 14 at Guarulhos and Viracopos

Disruption overview

Operational problems at São Paulo/Guarulhos International Airport and Viracopos International Airport on 16 April 2026 led to 107 delayed flights and 14 cancellations , affecting thousands of passengers across Brazil and on long-haul routes to Paris, Frankfurt, and Newark. Rain at Guarulhos, runway maintenance at Viracopos, staffing shortages, and technical issues combined to squeeze runway, gate, and turnaround capacity during the morning peak.

With pressure continuing into 17 April and knock-on effects possible through 20 April, travelers are being told to check their flight status before heading to the airport and keep receipts for any extra costs. Compensation is usually unlikely in disruptions like this, but airlines should still provide care such as rebooking, meals, refreshments, and overnight accommodation where needed.

Disruption details

Passengers traveling through São Paulo on 16 April 2026 faced widespread disruption after problems at São Paulo/Guarulhos International Airport and Viracopos International Airport delayed or canceled 121 flights during the morning and early afternoon. For many travelers, that meant missed connections, longer waits, and an uncertain start to their trip.

The main impact at the two airports was clear:

• 107 flights were delayed, and 14 were canceled.

• The worst disruption came between 6:00 am and 12:00 pm, when overnight long-haul arrivals overlapped with the first wave of domestic departures.

• The problems hit both Brazil’s domestic network and key long-haul routes to Paris, Frankfurt, and Newark.

The disruption reached well beyond São Paulo. Air France services between São Paulo and Paris Charles de Gaulle, Lufthansa flights to Frankfurt, and United Airlines services to Newark were among the international links affected. At Viracopos in Campinas, Azul Airlines saw knock-on delays across feeder flights from Salvador, Brasília, Recife, and other interior cities, leaving some passengers stuck in extended ground holds and others scrambling to make onward connections. The problems affected thousands of passengers during one of the busiest travel periods of the Brazilian autumn.

This wasn’t caused by one single issue. Morning rainfall at Guarulhos forced air traffic controllers to leave more space between aircraft, which reduced the number of arrivals the airport could handle each hour. At the same time, pre-planned runway maintenance at Viracopos cut available departure slots.

Pressure built further as ground-handling staffing shortages at both airports slowed boarding and baggage processing. Several overnight long-haul arrivals also reported unscheduled technical issues, which squeezed already tight turnaround times. Once the schedule started slipping, crews moved closer to their duty-time limits and some aircraft had to stay at the gate instead of getting back into rotation.

By mid-afternoon, the ripple effects had reached the transatlantic departure bank scheduled between 9:00 pm and 12:00 am. With little spare aircraft and gate capacity available, there was limited room to recover lost time. That helps explain why a disruption that peaked earlier in the day kept affecting flights much later on.

Guarulhos is especially exposed to this kind of pressure. Its monthly delay rate often rises above 20 percent, and cancellations are regularly above 1.5 percent even in more normal operating conditions. When weather, maintenance, and staffing issues land at the same time, recovery becomes much harder.

The strain was still continuing on 17 April 2026. Both airports were operating under pressure, no end time had been announced, and there was no formal ground stop or official capacity-reduction order in place. Knock-on effects could last through at least 20 April if similar weather patterns continue and infrastructure work remains in place.

If you’re flying through Guarulhos or Viracopos, it’s worth checking your flight status before leaving for the airport and contacting your airline if your plans have changed. Airlines are also advising passengers to keep receipts for meals, transportation, or hotels if the disruption leaves them out of pocket.

Because this disruption was driven by weather, airport maintenance, and staffing shortages, compensation is usually unlikely under Brazilian passenger rules and, for the European carriers involved, under EC 261. Still, that doesn’t mean you’re without support. Airlines should provide care and assistance during long delays or cancellations, including meals and refreshments, rebooking or a refund, and overnight accommodation with transportation if you’re stranded.
