Cancún is feeling a subtle shift in who’s landing and why. The airport has seen a decline in international passengers this year, and much of that drop can be attributed to lower demand from the United States. At the same time, Canada is suddenly carrying the load: Toronto and Montreal routes are not just growing but topping Mexico’s international rankings. The change matters on the ground—think hotel bookings, staffing, even which routes airlines keep or cut. Here’s what the official numbers say, and what it could mean next.
Cancún airport traffic is nuanced
Cancún International has seen a 4.7% year-to-date decline in international passenger traffic, with 720,800 fewer passengers from January through September compared to the same period last year. That’s the headline figure highlighted this week, and it squares with the operator’s own September release, which shows Cancun’s international tally at 14.74 million YTD vs. 15.46 million in 2024.
ASUR’s latest statement also captures the broader context: Mexico’s international traffic fell 6.5% in September, with total Mexico traffic off 4.5% year-over-year that month—signs of a softer shoulder season across the group’s Mexican airports, including Cancún.
Por Esto!’s breakdown, drawing on a STARC (Advanced Research Center for Sustainable Tourism, Anáhuac Cancún) routing snapshot, points to where the weakness is concentrated: US routes are cooling. Chicago is the standout decliner, followed by Denver and Dallas, with more minor drops in New York, Atlanta, and Houston. That pattern mirrors what local operators have reported through spring and summer.
Canada is carrying unexpected weight in 2025
The flip side is decisive—and it’s Canadian. For at least three consecutive months, the busiest international links to Mexico have not been US routes at all, but Cancún–Toronto and Cancún–Montreal. Por Esto! Flags reported +23.6% growth in Toronto and +37.9% in Montreal, as per its referenced STARC table. Independent coverage of the same STARC findings earlier this year also documented the Canadian surge, with Toronto and Montreal outpacing traditional US feeders. Canada is now driving the busiest Mexico-bound corridors.
That shift is consistent with other market signals in 2025: Canadian carriers have been adding Mexico capacity and promoting winter sun links hard, even as some US flows softened. For the airport and the destination, this changes seasonality, average length of stay, and pricing dynamics at the margin.
The mixed picture also shows up in ASUR’s monthly grid for September: Cancún total traffic fell 7.4% in the month, split between domestic softness and that larger international dip. Year-to-date totals remain immense by regional standards, but the composition of arrivals is clearly evolving. Bold travelers are still coming—just not always from the same places as last year.
What this means on the ground in Quintana Roo
For hotel managers and tour sellers, a 4.7% international YTD slide is noticeable but manageable—especially when the Canadian lift is this strong. Operators reliant on US weekenders may be feeling the pinch, while properties courting longer-stay Canadians could be faring better. Airline planners will keep doing what they always do: reward the routes that fill and trim the ones that don’t. If Chicago and Denver remain soft into winter, schedules could flex again; if Toronto and Montreal continue to lead, that capacity sticks—and grows.
There’s also a statewide lens. ASUR’s Mexico portfolio shows international traffic down 4.5% year-to-date through September at the group level, not just in Cancún. That suggests macro factors—from airfare and capacity shifts to traveler sentiment—are at play beyond a single market. Local policy and promotion still matter, but 2025’s demand map is being redrawn primarily by airline networks and traveler economics.
