Cyclone-Triggered Blackout Cancels 369 Flights in São Paulo, Disrupting Year-End Business Travel

Cyclone-Triggered Blackout Cancels 369 Flights in São Paulo, Disrupting Year-End Business Travel
A week after a powerful extratropical cyclone swept south-eastern Brazil, the knock-on effects are still grounding planes and upending corporate itineraries. Updated tallies released in the early hours of 16 December show 369 cancellations at São Paulo’s Congonhas and Guarulhos airports since the storm hit, with airlines imposing rolling schedule cuts to preserve minimal on-time performance.

The blackout—one of the city’s worst in a decade—took 1.3 million customers off the power grid, knocking out runway lights, baggage belts and security scanners. LATAM, GOL and Azul have activated fee-free rebooking windows covering tickets issued between 10 and 20 December, a rare concession during the lucrative holiday peak. Supply-chain managers report delayed courier shipments of engineering parts and clinical-trial samples that normally transit through Guarulhos’ cargo terminal.

For employers, the operational headache is compounded by Brazil’s reinstated e-Visa for U.S., Canadian and Australian nationals—meaning stranded executives must keep visa validity in mind when re-routing through Chile or Argentina. Travel managers are advising travellers to add at least four hours of buffer time for domestic connections through São Paulo this week.

At this juncture, online visa facilitator VisaHQ can ease some of that friction: its platform lets corporate travel departments upload passport scans in bulk, receive real-time status updates and secure Brazil e-Visas or transit permits—often within 48 hours.

Aneel, the federal power regulator, says it is examining whether repeated outages constitute “service failure” by utility Enel, a designation that can trigger fines or even termination of the concession (see separate story). The prospect of regulatory sanctions raises further questions about power reliability at Brazil’s busiest corporate gateway.

Companies running duty-of-care platforms should ensure push alerts are enabled for all staff flying into São Paulo and verify hotel generators can support high-bandwidth work demands—particularly for hybrid or digital-nomad employees relying on video conferencing.
