Today marks the official recognition of World Tourism Day, a global highlight of the power of travel sanctioned by the United Nations’ World Tourism Organization. The Travel Industry Association (TIA), based in  Washington, D.C., is leading the country’s participation in this international event.

“Tourism Enriches” is the worldwide theme and speaks to the many contributions and opportunities created by the $646 billion U.S. tourism industry.

Roger Dow, President and CEO of TIA, will join international tourism leaders in Lisbon, Portugal – the site of World Tourism Day’s official activities – to represent the United States in the day’s proceedings. In addition, TIA will speak on behalf of the U.S. travel industry at think tank sessions related to global tourism.

“Inviting more international visitors to the United States is a priority and an exciting opportunity for us, and World Tourism Day is another step in letting travelers know that America and the American people welcome their visit,” Dow said. “Nationwide, cities and states are greatly impacted by the economic, social and cultural benefits of travel.”
