U.S.-international air traffic passenger enplanements totaled 24.6 million during the month. While total traffic softened, inbound international travel remained relatively stable. Non-U.S. citizen air passenger arrivals reached 4.4 million, a modest 0.2% increase over June 2025. However, overseas visitor arrivals—which exclude travelers from Canada and Mexico and are tracked separately through the I-94 program—fell 1.8% year over year to 2.8 million.
Outbound international travel by Americans saw a steeper decline. U.S. citizen air departures to foreign countries totaled 8 million in June, down 3.2% from the previous year.
Mexico remained the United States' busiest international air travel market despite seeing one of the largest declines among top destinations. Combined arrivals and departures between the two countries totaled 3.3 million passengers, down 6.1% from June 2025. Canada followed with 2.8 million passengers, essentially flat with a 0.2% increase.
The United Kingdom ranked third with 2 million passengers, down 2.1%, while the Dominican Republic posted one of the strongest performances among the top markets, growing 3.3% to 1.1 million passengers. Germany rounded out the top five with 1.1 million travelers, a 3.4% decline year over year.
