This season’s flu outbreak may have flattened millions in the U.S., but it’s not keeping most travelers from packing up and flying out.

While some surgical facemasks have been spotted in airports in Charlotte, Miami and Dallas, very few travelers appear to be bailing on travel plans.

Travel Guard said that while questions about coverage in the event of sickness are the most common ones asked, “it’s hard to say whether or not there is more concern this year.”

Sandals has reported no flu cancellations, a refrain echoed by Denise Hangsbleden, owner of Travel Your Way in Belleville, Ill.

"I’ve had one client concerned about flu and noroviruses on cruises. The only reference I heard about the flu was more about a gym. Again, that is what insurance is for, whether for a cruise or land vacation," she said.

Where the flu has hit, and hit hard, is in offices and businesses. This year’s outbreak not only is more widespread than in years past, but the strain tends to make people sicker than usual and for longer.

At Cook Travel Agency in New York City, more than 40% of the staff of 35 has been laid low by the head-burning, cough-wracking, muscle-aching influenza.
