Travel to and within the U.S. grew 1.6 percent year-over-year in September, according to the U.S. Travel Association’s latest Travel Trends Index (TTI)—marking the industry’s 105th straight month of overall expansion.

But U.S. Travel economists add several strong caveats to the overall positive trend.

Growth in domestic travel is leveling off, for example. That segment had been strong in recent months, buoyed by robust consumer spending and consumer confidence reaching heights last seen in 2000. Business travel, which registered a faster rate of growth than leisure travel in August, appears to have plateaued; domestic travel in September was almost entirely supported by leisure travel, which grew at a decelerated rate of 1.8 percent.

It would also be easy to misconstrue the international component of the latest TTI, which showed 4.4 percent year-over-year growth. But with inbound having posted a sharp 2.2 percent drop in September of 2017, any year-over-year improvement at all is liable to appear overinflated.

Furthermore, the international Leading Travel Index (LTI) predicts that market will not expand any further at all in the next six months.

“We’re seeing something of a perfect storm of factors that could suppress international demand for travel to the U.S.,” said U.S. Travel Senior Vice President for Research David Huether. “The U.S. dollar has been on another very robust strengthening trend since April of this year, while the global economy has been cooling off considerably overall. That, coupled with political uncertainty in Europe and rising trade tensions, is a bad-news recipe for inbound travel.”

The TTI is prepared for U.S. Travel by the research firm Oxford Economics. The TTI is based on public and private sector source data which are subject to revision by the source agency. The TTI draws from: advance search and bookings data from ADARA and nSight; airline bookings data from the Airlines Reporting Corporation (ARC); IATA, OAG and other tabulations of international inbound travel to the U.S.; and hotel room demand data from STR.
