AIRPORT HUB · RIO DE JANEIRO
Rio’s Galeão closed 2025 with 17.9 million passengers — up 23.5% in a single year — as the Santos Dumont cap funnelled growth north and Southern Cone demand did the rest. The international ledger, 5.7 million, is the airport’s best since the terminal opened in 1977.
Galeão’s surge is imported demand: Argentine outbound rebounded on the exchange rate, JetSmart stimulated the low-cost layer, and Aerolíneas Argentinas (+36%) and Avianca (+29%) piled in. International traffic grew 31% at points during the year — against a Brazilian market average of 19% — and North American connectivity widened with first-ever nonstops to Toronto and Montreal.
Brazil as a whole closed 2025 with a record ~130 million air passengers; international traffic reached 25.8 million (+13.6%), and Galeão handled about 10% of the country’s international flight volume. Cargo set records too — a weekly Atlas Air freighter now lifts up to 100 tonnes per flight out of GIG.
The system is deliberately coordinated: Santos Dumont, the 1930s gem on the bay, is capped at 6.5 million passengers a year and a 400 km route radius, pushing anything beyond the São Paulo shuttle to Galeão. The cap was a condition of the revised GIG concession and is endorsed by the federal audit court; ANAC has discussed easing it since mid-2025, but city hall and the concessionaire argue it is what makes the 2026 concession rebid viable.
For travelers the split is practical: SDU sits 2 km from downtown and now plugs into the VLT tram at its doorstep; GIG is 20 km north on Governador Island, reached by BRT corridors and the Linha Vermelha. Pick SDU for the Congonhas shuttle and regional hops, GIG for everything international — and watch the rebid: Rio hosts Routes Americas in March 2026, and the route announcements are stacking up.
The TIO read: Galeão is the rare concession reset that actually delivered — 23.5% growth with half the capacity still in reserve. The risk is political, not operational: any pre-rebid loosening of the Santos Dumont cap would shave GIG’s domestic feed. Until the 2026 auction settles, assume the current split holds and book international growth into GIG.
