The Air Traffic Flow Management (ATFM) Centre of Brazil’s Airspace Control Department (CGNA) released its daily operational briefing at 12:44 UTC on 12 May 2026, outlining preferred IFR routes and capacity measures designed to smooth traffic during the pre-holiday spike expected later this week. The bulletin covers airport slot allocation, severe-weather avoidance plans (SWAP) and runway-maintenance windows across the national network. Why it matters: Brazil’s autumn public-holiday calendar often triggers last-minute corporate travel and cargo charters. By publishing tactical flow restrictions 24 hours in advance, CGNA allows airlines and corporate‐flight departments to re-file flight plans, mitigating delay propagation. Congonhas (São Paulo) and Santos Dumont (Rio) are under ‘level yellow’ monitoring for runway capacity, while Brasília and Recife show normal operations. Key measures: • Preferred routing corridors have been activated between Rio/São Paulo and Northeast airports to bypass forecast convective cells. • A SWAP is on standby for 13–14 May should frontal systems intensify over the Southeast. • Airlines must confirm repetitive flight plans (RPL) for the 07-13 May cycle by 18:00 local time or risk slot withdrawal. Corporate-aviation impact: Business-jet operators holding flexible departure times may benefit from reduced ATFM delay credits if they file after 22:00 local. However, ad-hoc slots at Congonhas remain scarce; mobility teams moving senior executives should consider Campinas or Catarina as alternates. Next steps: CGNA will issue an updated Severe Weather Avoidance Plan at 06:00 UTC on 13 May. Travel managers and airline OCCs should subscribe to the SISCEAB alert feed to receive push notifications.
