A powerful winter storm sweeping across the eastern United States forced airlines to cancel or delay dozens of trans-American flights on Saturday, with ripple effects felt at Brazil’s two largest international gateways. According to airport operator GRU Airport, at least 11 departures from São Paulo/Guarulhos to New York, Boston and Miami were scrubbed between 06:00 and 14:00 local time after JFK and Logan airports issued ground-stop orders. Rio de Janeiro’s Galeão registered a further six cancellations.
LATAM, American Airlines and Delta have activated rebooking policies that allow passengers flying between 24 and 26 January to change dates or routes without penalty. Cargo consignments—including high-value pharma products normally shipped in the lower hold—were re-routed via Atlanta and Mexico City, adding 24–48 hours to delivery schedules for clinical-trial materials and e-commerce goods.
The National Civil Aviation Agency (ANAC) reminded carriers that Brazil’s Resolution 400 still obliges them to provide meals, lodging and alternative transport options even when delays stem from force-majeure weather abroad. Travel-risk managers advising multinational staff were urged to monitor U.S. Federal Aviation Administration alerts and to confirm that employees possess Brazil-issued proof of yellow-fever vaccination; extended layovers could trigger re-entry health checks at Brazilian borders.

For travelers scrambling to adjust itineraries, VisaHQ can streamline one more piece of the puzzle: documentation. Through its Brazil portal (https://www.visahq.com/brazil/), the platform lets passengers instantly check entry rules for alternate transit points, arrange rush visa processing, and renew expiring passports—crucial services when sudden reroutes send people through unexpected jurisdictions.
Business-travel analysts say the disruption underscores the vulnerability of Brazil-U.S. air corridors, which handle roughly 30 % of all Brazilian corporate travel. Airlines have struggled to re-build spare capacity since the pandemic, meaning irregular operations quickly exhaust available seats. The storm hit just as Guarulhos enters Carnival peak season, when load factors already exceed 92 %.
With meteorologists forecasting another snow band early next week, companies are re-routing critical personnel through Houston, Dallas or Panamá City, while freight forwarders are shifting temperature-controlled shipments onto freighters departing Viracopos. The episode also reignites debate over whether Brazil should sign the Montreal Convention 1999’s updated liability clauses to clarify compensation rules in international delays.
