WINDSOR LOCKS, Conn. (WWLP) – It’s just over a week until Christmas and millions are expected to travel for the holidays this year. It was a busy morning at Bradley International Airport as people begin to make their way to visit loved ones for the holidays.

“There’s a lot of people here. I didn’t think it would be this busy,” said Manuel Morgan, who was flying home to Chicago.

According to AAA, about six million people are expected to fly. The busiest days are predicted to be Thursday, December 23rd and Monday, January 3rd.

“The last time I was on a plane, I did feel safe,” Morgan said. “It was comfortable.”

Across the country, COVID-19 case numbers are rising as the omicron variant spreads. To keep passengers safe, everyone two-years and older inside an airport and on an airplane needs to wear a mask. The Centers for Disease Control and Prevention is also recommending only fully vaccinated people travel this holiday season.

“It helps me think people are not going around and spreading it more,” said Robbie De Lang, who’s traveling to Belgium.

International travelers have additional rules to follow. They need to show proof of a negative COVID-19 test within 24 hours of their flight back to the U.S. regardless of vaccination status.

“My school also has an additional testing they require that you mail in two weeks before,” said De Lang.

The CDC says people flying within the United States do not need to get proof of a negative COVID-19 test, but they do recommend getting one just to be safe, especially unvaccinated people. There is a testing site at Bradley open seven days a week located near the baggage claim.
