International arrivals to the United States dropped 4.3% in September to 2.7 million, according to preliminary National Travel and Tourism Office data released Friday. The decline extends a near-12% drop in August and leaves year-to-date arrivals 5.7% below 2024 — a gap earlier World Cup traffic could not close.

Skift's editor's-note summary, the Skift Take, frames the geography bluntly: "Gains from China and South America haven't been enough to make up for declines in travel from Western Europe." For U.S. hotels, inbound tour operators and destination marketing organizations that lean on transatlantic feeder markets, that split is the real story, not the headline percentage.

Where the losses are coming from

The weakness is geographic, not uniform. Western Europe has historically generated the highest per-visitor spending among overseas source markets, and losing share there is a different revenue problem than losing visitors from a smaller origin region.

China's gains and South America's growth are real, but they aren't moving at the pace or scale needed to backfill European softness on a per-trip basis. Even if Asia-Pacific and Latin America finish 2025 ahead of 2024, the composition of those gains matters: a Chinese independent traveler at a mid-scale New York hotel spends differently than a multi-city European package tour. Aggregating "overseas arrivals" hides that mix, which is why revenue managers will be parsing the country-level cuts when NTTO releases them.

How the year is shaping up

August's near-12% drop is the steepest single-month fall in the dataset so far this year. June and July also came in below 2024, even with World Cup visitors in the mix.

September is the fourth consecutive month of year-over-year losses, and the cumulative shortfall is now baked into the final two months of the calendar. For sellers of inbound travel, the math is straightforward: a 5.7% YTD shortfall against 2024 means roughly one in every eighteen expected overseas bookings hasn't materialized.

The gap can't be closed with December promotions alone. Hotel revenue managers and inbound tour operators are watching the September print more closely than a routine monthly update would warrant.

What the data doesn't tell you

The preliminary NTTO release doesn't break out which Western European countries drive the September slide, nor how much of the China or South America rebound is real versus a base effect. Without those cuts, suppliers can't yet tell whether the weakness reflects European consumers cutting U.S. trips, a transatlantic airline-capacity squeeze, or visa-processing friction earlier in 2025.

Treat the 4.3% headline as a signal, not a diagnosis. The figures are preliminary and subject to revision — a caveat that rarely flips the trend but matters when monthly swings run this narrow.

What it means for travel sellers

DMOs that built 2025 marketing plans around European shoulder-season demand now have a thin runway to recalibrate. If the trend holds, operators with bundled European itineraries will renegotiate airline blocks, and OTAs with U.S.-bound European traffic will reweight paid search.

China has helped, but it hasn't replaced European volume on most P&Ls. The next NTTO release, covering October, will tell suppliers whether to plan for a soft year-end or a structural reset heading into 2026.
