"It's a little disconcerting, but I don't think it's anything unusual these days," traveler Charlotte Ingles said.
Ingles said she wasn't too surprised or worried after hearing about an apparent terror plot.
The Department of Homeland Security said it is taking steps to enhance air security including heightened cargo screening and additional security at airports.
A spokesperson for RDU told ABC11 Eyewitness News there were no delays or security changes for cargo planes on Friday and passengers at RDU said they didn't notice anything unusual at airport security checkpoints in other parts of the country.
"It actually moved a little bit faster, I suspected that there might be a bit of a wait," traveler Jamie Leonard said.
Leonard, who flew in from Atlanta, said she also heard the news about the threat and couldn't help but think about it.
"Just that there was a threat and it was on the news and that security would be heightened," she said. "Definitely makes me nervous, makes me worried."
However, President Barack Obama has been urging people not to let the international terror threat impact their travel plans.
And Ingles said she still plans to go to the UK this holiday season regardless of the threat.
"You can't live your life in fear, so you just got to keep going and trust the people that are in charge and that are in a position to do something about it," she said.
Meanwhile, airports across the country, including RDU, did implement a new procedure for pat-downs Friday, but it was already in the works well before the threat.
