Leisure travel is set to remain strong this year as six out of ten U.S. adults plan to travel for leisure during the next six months, unchanged from the percentages recorded this time of year in the previous two years, according to leading travel research firm, MMGY Global.

According to the company’s latest Traveler Sentiment Index, these consumers plan to take an average of 2.5 trips, unchanged from 2017 (2.5 trips), while 28 percent of respondents plan to spend more on vacation this year versus last, and only 12 percent plan to spend less.

The overall travelhorizons Traveler Sentiment Index (TSI), which measures U.S. adults’ interest in travel, time available for travel, personal finances available for travel, perceived affordability of travel, quality of service, and perceived safety of travel, currently stands at 116, up one point from this time last year (115).

MMGY believes the slight increase can be attributed to a five point increase in perceived affordability of travel (176) and a four point increase in personal finances available for travel (127).
