The good folks over at Ypartnership just released their updated U.S. travelhorizons survey, and while the results don’t look much worse, they don’t look any better either. Let’s call it more of the same.

The outlook for business travel remains mixed, with only 18 percent of adults planning at least one trip (including business meetings and conventions) between now and April 2010, up slightly from the 17 percent last July. Of those who will be travelling, the number of intended trips has been rising steadily throughout the year—from an average of 3.3 trips in April to 4.8 trips in October. This average is being driven up by a relatively small percentage of business travelers though, as only 6 percent intend to take more business trips during the next six months (24 percent expect to take fewer).

On the leisure side of the coin, 53 percent of all U.S. households are planning at least one leisure trip between now and April 2010, down slightly from the 56 percent who stated the same intention last year. Concerns about “the household budget” remain the primary deterrent to future leisure travel (cited by 39 percent of those not planning a trip). However, the incidence of this concern is now at the lowest level since Ypartnership began to include the question in the survey.

Like business travelers, leisure travelers intend to take a few more trips during the next six months, as the average number of trips is up to 3.0 from 2.8 last year.

“In summary, the horizon line for the next 6 months doesn’t reveal any significant change in the complexion of demand for travel services,” said Peter Yesawich, the firm’s chairman and CEO, in a recent blog posting. “Demand for leisure travel services will continue to fill the majority of occupied seats and rooms, with demand for business travel services remaining essentially flat.”
