Air Canada has leaned on its sixth freedom franchise — carrying passengers connecting between the US and international points via its Canadian hubs — to offset a softening in US transborder leisure demand that took hold last year, and the carrier says the model still has room to grow.

The slowdown, which Air Canada attributes to shifting geopolitical trends and unpredictable trade policies, hit the leisure segment of the transborder market specifically. Corporate travel held up better, and together with the sixth freedom operation it provided a shield for the airline's overall transborder performance.

Sixth freedom traffic is structurally important for Air Canada because it monetizes the carrier's hub positions in Toronto, Montreal, Calgary and Vancouver with passengers who never have Canada as an origin or destination. When point-to-point demand wobbles on a single market — as US leisure demand did — the connecting flows diversify the revenue base across a wider set of origin and destination pairs.

Why does the transborder leisure market matter to Air Canada?

The US–Canada transborder market is one of the largest international country-pair markets in the world, and leisure traffic is a significant component of it. A demand shock in that segment, driven by external factors rather than airline-specific issues, forces carriers to reassess capacity deployment. Air Canada's response has been to keep building the network around flows it believes remain resilient: corporate travel and global connecting traffic.

The airline's assessment is that geopolitical and trade unpredictability has not gone away — if anything, it has become the operating norm. Fuel remains a wildcard for airlines worldwide, adding another variable to network and pricing decisions. Even so, Air Canada says it remains confident in its transborder positioning.

What comes next for the network?

Air Canada believes substantial runway exists to grow the sixth freedom business, and continues network planning efforts aimed at those connecting travelers. That points to continued optimization of schedules, banks and long-haul destinations from its Canadian hubs to capture passengers flying between US cities and points in Europe, Asia and beyond.

The strategic logic is straightforward. While US leisure demand proved vulnerable to geopolitical and trade shocks, connecting passengers choosing an itinerary through Canada respond to schedule quality, total journey time and price — factors an airline can control. Growing that franchise reduces Air Canada's exposure to any single demand pool, including the volatile US leisure segment.

Fuel remains the principal cost-side uncertainty. Air Canada does not control the fuel price, but a diversified traffic base gives it more pricing flexibility when energy costs move.

The carrier's stance amounts to a bet that structural advantages — hub geography, an established connecting franchise and durable corporate demand — can absorb macro-level volatility in trade policy and geopolitics. For now, Air Canada intends to keep expanding the sixth freedom operation, treating uncertainty not as a reason to retrench but as the baseline condition for planning its next round of network decisions.
