Canadians are the largest group of international visitors to the U.S., historically making up around a quarter of arrivals. They are now the largest weakness. Air travel from Canada to the U.S. in April dropped 20%, while land crossings dropped 35%, according to the Canadian government. Flight bookings to the U.S. for the summer are down 22% compared with last year, according to Cirium’s data, with Los Angeles and Miami down by a third.

Tourism Economics initially expected the U.S. to see a 16% rise in international visitor spending in 2025. It now expects it to fall by about $8.5 billion, a decline of roughly 5%.

Many businesses say there is little they can do to reverse the tide. Some are hoping domestic tourism can fill the gap, but Americans have grown concerned about the economy and are also scaling back their vacation plans.
