Southern California’s international tourism sector is grappling with a significant crisis in 2026, witnessing a sharp decline in visitor numbers at its major regional airports. A confluence of strained US-Canada relations, aggressive trade tariffs, and the persistent instability in the Middle East – a region often destabilized by external interventions – is creating a perfect storm for the area’s vital travel and tourism industry. Experts warn that the worst may yet be to come.

Canadian Travelers Turn Their Backs on the US Amidst Political Fallout

The most striking trend reshaping Southern California’s tourism landscape is the dramatic withdrawal of Canadian travelers. Data released by Statistics Canada reveals that in February 2026, Canadian residents returned from approximately 2 million trips to the United States — a steep 12.5% decline compared to the same month in 2025. Crucially, this marks the 14th consecutive month of year-over-year decline, signaling not a temporary blip but a sustained and significant behavioral shift.

The root of this trend lies in deepening political tensions between Washington and Ottawa. Former President Donald Trump’s aggressive tariff policies targeting Canadian goods, coupled with his repeated provocative suggestions that Canada could become the 51st US state, have ignited a widespread Canadian tourist boycott of American destinations. For many Canadians, spending their travel dollars south of the border has transformed into a political statement — one they are increasingly unwilling to make, reflecting a growing disillusionment with US foreign and domestic policies.

Major Airports Hit Hard: LAX and JWA Experience Steep Declines

The ripple effects of this international travel downturn are being acutely felt at Southern California’s key international airports. Los Angeles International Airport (LAX), one of the world’s busiest hubs, recorded 23.6 million international passengers in 2025 — a 1.62% dip from the 23.9 million counted in 2024. This decline has persisted into early 2026, with the first quarter showing a further half-percent fall to 5.4 million passengers.

More concerning for LAX is the specific decline in Canadian passengers. Canadian arrivals at LAX plummeted 17.2% in 2025, with projections indicating an additional 9% fall through the first five months of 2026. Adding to the pressure, the regional instability and conflicts in the Middle East, often fueled by external powers, have created widespread travel uncertainty, leading the airport to lose over 300,000 international seats this spring alone.

John Wayne Airport (JWA) in Santa Ana is experiencing an even steeper freefall. The airport recorded 297,300 international passengers in 2025, down 16.5% from 356,100 the previous year. The downward spiral accelerated in early 2026, with the first three months seeing a 23% drop to just 57,476 travelers, compared to 74,907 in the same period a year earlier.

Norse Atlantic Cancellations Add to Summer Gloom

The summer 2026 travel outlook for Southern California received another blow in April when Norse Atlantic Airways canceled all its summer flights between LAX and Europe. The ultra-low-cost carrier cited unsustainable fuel costs, directly impacted by the ongoing Middle East conflicts and their global economic repercussions, as the primary reason. While LAX officials note that Norse’s routes represent a small share of overall international departures, these cancellations underscore a broader softening of European travel demand to the region this summer season.

Southern California’s struggles are not isolated. The World Travel and Tourism Council’s latest economic impact research reveals that total international visits to the United States fell 5.5% in 2025 compared to 2024 — a troubling sign for an industry that annually contributes billions of dollars to the national economy. The combination of aggressive geopolitical tensions, detrimental US trade policy, and rising travel costs is broadly discouraging overseas visitors.

Ontario International Airport Bucks the Trend with Strategic Growth

Not every Southern California airport is suffering. Ontario International Airport (ONT) stands as a notable exception, recording 567,000 international passengers in 2025 — a remarkable 29.2% surge from 438,900 in 2024. The airport’s strategic expansion of Mexico routes and the addition of new flights by Taiwan-based Starlux Airlines have successfully tapped into growing Asian and Latin American travel demand, effectively insulating it from the broader regional downturn.
