Holiday travelers may notice that the TSA has been expanding the use of facial recognition technology. It's now at more than a dozen airports across the country.

The agency says it's evaluating the efficiency of this technology before taking it nationwide.

The technology matches your face to the ID a passenger provides at security.

The agency is also testing another system, on a more limited scale, where a person's face is their ID. The machine compares a person's face to a database of pictures the government already has. With new technology also comes new concerns.

"There's a consent aspect, there's a privacy aspect, and there's a security aspect that really needs to be considered a lot more thoughtfully before TSA moves forward with any of this," said India McKinney, director of federal affairs with the Electronic Frontier Foundation, a digital rights group.

McKinney contends there are more privacy protections around the machine checking a person's ID than there are with the system that scans a traveler's face. She notes that the machine checking an ID does not have to be connected to the internet.

McKinney also says it's a mistake to assume the technology will work 100% of the time for everyone.

The TSA said it's continuing to monitor its systems to ensure there is no inherent bias. The agency adds use is voluntary.

"The question, when they say something is voluntary is, how easy is it to opt out? And we've gotten conflicting reports on exactly how easy that is," McKinney contends.

She believes it's going to be up to Congress to make sure people continue to have the ability to opt-out.

HEBRON, Ky. —

Now that more travelers are getting vaccinated, the Centers for Disease Control and Prevention is altering its suggestions for flying a bit and it's bound to make things easier for travelers.

New guidelines are getting us closer to the old days. The CDC has updated its travel recommendations for vaccinated Americans saying that if you have your shots, the likelihood of contracting COVID-19 while traveling is low.

"A lot of people look to the CDC as the authority on the manner and a lot of the people turn to the WHO as well so that fact that the CDC had that to say about the vaccine and it being low-risk that makes people a lot more comfortable and it's a great step in the next direction," said traveler Casey Butler.

There are also more recommendations from the CDC. Fully vaccinated travelers do not need to get tested before or after travel unless the destination requires it and fully vaccinated people do not need to self-quarantine.

"I got first shot on Dec. 22, second dose Jan. 21 at the University of Cincinnati," Mya Sabai said.

Sabai says he hasn't stepped foot on a plane since before the pandemic began.

"I'm relieved that we can travel more safely and confidently," he said.

Others said they feel better about jetting off now than they did months ago.

"I'm comfortable right now traveling. I don't have any problem traveling anywhere in the world because of the vaccine, everyone's getting the vaccine," Akosua Yeboah said.
