May International Air Travel Data Shows the U.S. Inbound Gap Is Still Real
Fresh May 2026 international air travel data points to a split U.S. travel market: airports remain busy, Americans are still taking overseas trips at levels well above 2019, but foreign visitor demand into the United States is not recovering at the same pace.
According to National Travel and Tourism Office data summarized in a June 15 market report, international air passenger enplanements to and from the United States totaled 22.7 million in May, down 1.2% from May 2025 but still 103.3% of the May 2019 level. The headline number therefore does not suggest a weak international air market. The more important detail for U.S. destinations, hotels, tour operators and airport-area services is who is filling those seats.
Non-U.S. citizen air passenger arrivals from foreign countries reached 4.5 million in May, down 4.5% from a year earlier and only 82.4% of the May 2019 volume. Overseas visitor arrivals, excluding Canada and Mexico, totaled 2.8 million, down 6.5% year over year. Year to date through May, overseas visitation to the United States was down 4.8% from the same period in 2025.
Busy airports do not mean a full inbound recovery
The data matters because it separates airport activity from tourism recovery. A major gateway can look crowded while still receiving fewer foreign leisure and business visitors than the U.S. travel economy would normally expect.
U.S. citizen departures to foreign destinations totaled 6.8 million in May. That was down slightly from May 2025, but still 22.7% above the 2019 level. In practical terms, Americans are continuing to spend aggressively on international trips even as the United States is still working to rebuild overseas demand into its own cities, attractions and resorts.
For travelers, the effect can show up in uneven pricing and availability. Outbound-heavy routes may stay firm because Americans are still flying abroad. At the same time, some U.S. hotels, attractions and destination marketers may be competing harder for international visitors whose recovery remains incomplete.
The largest gateways remain central to the story
New York JFK, Miami, Los Angeles, Chicago O'Hare and San Francisco were the leading U.S. airports for international travel in May, according to the same NTTO-based data. JFK handled about 2.9 million international passengers, followed by Miami with 2.1 million, Los Angeles with 2.0 million, and both Chicago O'Hare and San Francisco at about 1.4 million.
That concentration makes airport choice and ground logistics more important for both inbound visitors and U.S. residents returning from overseas trips. Travelers using major gateways can compare flight options through New York JFK, Miami International Airport, Los Angeles International Airport, Chicago O'Hare and San Francisco International Airport before locking in an itinerary.
Arrival timing also matters. International travelers should treat immigration, baggage claim, customs, terminal transfers and ground transportation as part of the same trip plan rather than a separate afterthought. Confirmed airport transfer resources for JFK, MIA, LAX, ORD and SFO can help travelers compare pickup options and build more realistic buffers.
Mexico, Canada and Europe show different demand signals
The largest country-pair markets in May were Mexico, Canada, the United Kingdom, Germany and Japan. Total air passenger travel between the United States and Mexico reached about 3.0 million passengers, down 6.7% year over year. Canada followed at 2.5 million, down 0.7%, while the United Kingdom was at 1.9 million, down 2.3%. Germany declined 7.4% to 966,000 passengers, while Japan rose 2.7% to 930,000.
The Canadian picture is especially important because Canada is a core inbound market for the United States. Statistics Canada reported on June 11 that Canadian-resident return trips from the United States rose 9.5% in May compared with May 2025, marking the second straight year-over-year increase since December 2024. Skift, citing the same Canadian data, noted that the rebound still left total Canadian trips to the U.S. nearly 29% below May 2024 levels.
That makes May a mixed signal rather than a clean rebound. The U.S. is seeing some improvement from Canada after a deep slump, but the broader inbound gap remains meaningful for border states, leisure cities, shopping destinations, hotels and attractions that rely on Canadian and long-haul overseas visitors.
Why the data matters for U.S. travel planning
For the U.S. travel industry, the May data points to a market that is active but uneven. Airlines may still see strong international traffic because U.S. outbound demand is elevated. Hotels and attractions, however, may not benefit equally if a larger share of international seats is carrying Americans out of the country instead of visitors into the United States.
For travelers, the takeaway is more practical than abstract. A busy international airport does not automatically mean every U.S. destination is in peak inbound-demand mode. Travelers should compare total trip costs across airfare, hotel location, airport transfers, rental cars, event calendars and arrival timing.
At large gateways, airport car-rental planning can be especially important when international arrivals, domestic connections and local traffic converge. Travelers who need a vehicle after landing can review car-rental options for JFK, MIA, LAX, ORD and SFO before arrival.
The recovery remains a marketing challenge
NTTO's longer-term forecast still expects total international visitation to the United States to rise in 2026 and continue growing through 2030, helped in part by major events including the FIFA World Cup. But the May air travel data shows why the recovery cannot be judged by airport volume alone.
For now, the U.S. international travel market is not weak, but it is unbalanced. Americans are still traveling abroad in large numbers, major gateways remain active, and some regional flows are improving. The harder task for the U.S. travel economy is converting that activity into a stronger inbound visitor recovery.
