Friday morning, the state department issued a global travel warning to all U.S. citizens, but so far travelers at Salt Lake International have noticed no difference.
"Didn't seem like there was any more security measures than usual, lines were long at LAX, but they always are," says David Elliott.
The warning comes with a focus on the Middle East and North Africa and it identifies Al Qaeda as a specific threat.
Officials say terrorist attacks could go beyond that region, but some say they feel safe on American soil.
"It's in the back of my mind, but it doesn't bother me too much," says Elliott.
Even with a sense of security here at home, others say it's a good reminder to keep their guard up.
"We all need to be more observant and cautious and be familiar with our surroundings. Let somebody know if we are concerned," says Sue Stites.
That's exactly what the state department is calling for as it reminds citizens that public transportation and tourist sites are potential targets.
The global warning will remain in place through the month of August.
