Brazil’s busiest airport began the new year under a cloud—literally—as heavy summer rain and an air-traffic-control staffing shortfall rippled through São Paulo–Guarulhos (GRU) on 3 January. Flight-stats aggregator FlightAware logged 192 delays and two cancellations affecting services to London, Madrid, Lisbon and New York. LATAM bore the brunt with more than 100 delayed rotations, while GOL, American Airlines and TAP Air Portugal also reported double-digit disruptions.
Airport operator GRU Airport said two remote stands in Terminal 3 flooded overnight, forcing a last-minute reshuffle of wide-body gate assignments. Simultaneously, the Air Force-run ATC centre (CINDACTA I) invoked flow-control measures after unexpected sick leave reduced night-shift staffing below minimum thresholds. Departure slots were metered at 22 movements per hour between 05:00 and 09:30 local time.
If the schedule chaos means you suddenly need to reroute via another country or adjust stopovers, VisaHQ can smooth the paperwork side of those changes. Its Brazil portal (https://www.visahq.com/brazil/) offers expedited visa and e-visa processing, real-time entry-rule updates and corporate dashboards that let TMCs manage multiple travelers at once—handy when flights move faster than consulates.
![Storms and Staffing Crunch Trigger 192 Flight Delays at São Paulo–Guarulhos]()
For corporates the timing is awkward: the first business week of January typically sees a surge in international assignees returning to Brazil and exporters heading to trade fairs such as CES in Las Vegas. Travel-management companies (TMCs) advise clients to build longer connection buffers and to monitor re-accommodation policies. LATAM and GOL are offering fee-free rebooking for travel through 7 January.
Aviation analysts warn that climate-driven storm intensity and chronic staffing gaps could make such days more common. Guarulhos handled a record 43.6 million passengers in 2024, yet its main runway operates close to capacity during morning peaks, leaving little slack when weather or labour issues strike.
Frequent-flyer programmes are already adjusting. Delta SkyMiles members experienced soft-landing extensions for elite-status qualification flights disrupted by the storm, hinting at a trend of more flexible performance metrics as airlines grapple with operational volatility.
