Las Vegas tourism continues its slump, with flight passengers down nearly 10% even amid Grand Prix

The city hosted the Las Vegas Grand Prix last month, which was expected to boost tourism.

The three-day Las Vegas Grand Prix was sold out, with more than 300,000 fans attending, according to Reuters.

Emily Prazer, CEO of the Las Vegas Grand Prix, told Reuters the organization was proud of the sold-out event.

"We elevated the guest experience at every turn and created iconic cultural moments that could only happen in Las Vegas, all while staying firmly rooted in what matters most - the race," said Prazer.

The event faced some controversy, with racing star Max Verstappen describing the race as something that was "99% show and 1% sporting event."

International visitors to Vegas were also down in November, with 239,500 tourists compared to 303,834 tourists last year.

The Las Vegas Convention and Visitors Authority (LVCVA) held a board of directors meeting over the summer to address the tourism decline, highlighting the lower number of international visitors.

Steve Hill, LVCVA president, reportedly spoke about the effect that tariffs have had on both returning and potential new visitors. 

"Some of the decisions our administration has made around international relations [have] caused a drop in tourism," said Hill, according to local outlet KTNV Las Vegas.

Rick Harrison of the Gold & Silver Pawn Shop in Las Vegas previously told Fox News Digital he remains hopeful tourism would pick up, but acknowledged the city hasn't been getting as many visitors as it once did.

"I'd say probably 40% to 50% of the people I get are international," said Harrison.
