Ottawa's international airport had a busy year in 2025 — more travellers passed through its terminals than the year before. But dig into the numbers and a clear trend emerges: while overall traffic was up, the airport's U.S. routes lost momentum as the year wore on.
According to the Ottawa International Airport Authority's annual report, passenger volumes to and from the United States climbed in the first half of 2025, continuing what had been a steady post-pandemic recovery. Then the second half arrived — and the numbers reversed course, dropping by enough to drag down the full-year performance on cross-border routes.
A Tale of Two Halves
The pattern is striking because it suggests something shifted in traveller behaviour mid-year. Early 2025 looked like more of the same rebound story airports across Canada had been riding since 2022. Canadians were flying again, booking Florida getaways and New York weekends, and Ottawa's airport was benefitting.
But by summer and into the fall, fewer Ottawa-area residents were choosing U.S. destinations — or at least, fewer were flying there directly. Whether that reflects broader economic pressures, a stronger preference for domestic and European travel, or the lingering effect of Canada-U.S. tensions on travel sentiment isn't spelled out in the report, but the timing lines up with a period when cross-border travel became a topic of national conversation.
Overall Growth Still a Positive Sign
Despite the U.S. softness, the airport's headline number is still a good-news story. Total passenger counts were up year-over-year, which matters for an airport that competes with Toronto Pearson and Montreal-Trudeau for the Eastern Ontario travel market. More passengers means more revenue for the airport authority, which in turn funds terminal improvements, gate expansions, and the route development that attracts new airlines.
Ottawa's airport has been on a steady growth path, adding international connections and improving its appeal for business travellers who would otherwise drive to Toronto or Montreal for better flight options.
What It Means for Ottawa Travellers
For anyone planning to fly out of the Macdonald-Cartier International Airport in 2026, the trends are worth watching. If airlines notice softening demand on U.S. routes, they may reduce frequencies or redirect capacity — which could mean fewer direct options to American cities. On the flip side, if carriers see opportunity in the non-U.S. growth, Ottawa could see new or expanded routes to European or sun destinations.
The airport authority hasn't announced any major route changes tied to the 2025 numbers, but the annual report gives airlines and partners the data they need to make those calls over the coming months.
For now, Ottawa's airport is bigger and busier than it was a year ago — just a little less American in its flight map.
