Airports across the country continue to tighten their security after the U.S. State Department issued a national terror alert for one of the busiest travel weeks of the year.
The department is urging Americans to be on alert themselves and report any suspicious activity.
"It's just something since 2001 that we have had to sort of live with, sort of get use to," said Quinn Moran of California.
While some travelers said they were surprised to hear of the alert, they said heightened security is something they've come to expect.
In fact, according to a CBS poll, nearly 70 percent of Americans believe a terrorist attack is imminent and likely to happen within the next few months.
"Flying you never really think about it too much because you're just going to drive yourself nuts," said Mike Flynn of Massachusetts.
The U.S. State Department issued the travel alert on Monday, which prompted airports around the country, including Bradley International Airport in Windsor Locks, to beef up their security.
Eyewitness News saw several officers walking around, including a bomb-sniffing K9 unit.
"It does concern me a little bit," said Maxuel Cruz, a traveler. "We're seeing a bit more activity here. But I don't think it will change people's plans much."
The alert came almost two weeks after the deadly attacks in Paris that left 130 dead.
It is expected to remain in effect until Feb. 24.
Officials at Bradley said they do not comment on security changes, but said safety is their top priority.
