DFW AIRPORT You had to read the fine print to know that anything out of the ordinary is going on in the world of travel this weekend.
Only a sign posted next to the TSA security line at Dallas/Fort Worth International Airport mentioned that a worldwide global travel alert was in effect for Americans as a result of an increased terror threat.
"Yeah, I heard a little bit about it before I left, but I wasn't aware that it was that concerning," said Tracey Brown.
The U.S. Department of State issued a global travel alert on Friday.
On Sunday, it was more like background noise rather than a strong message to people whose plans to travel overseas had already been made far in advance of the alert.
Brown's son was on a plane headed for London from DFW Airport. She said he left well prepared, even though she hadn't heard much more than a blurb about the travel warning.
"He has all the game plan," she said. "He has all of his facts and where to go when he gets off the flight, who to look for, and phone numbers. All of that."
All of those things are good to have in a foreign place, but the State Department says Americans should take extra steps to be safe abroad during the month of August.
It suggests travelers sign up for State Department alerts and to register with the U.S. Consulate in the countries they visit.
The State Department also urges travelers to sign up for the Smart Traveler Enrollment Program (STEP), which makes it easy for a U.S Embassy or Consulate to contact you during an emergency.
The travel alert was not specific to airports, and a spokesperson for DFW Airport told News 8 airport security is doing nothing out of the ordinary as result.
"Hopefully there's not too much to be concerned about," said Shannon Holt as she dropped off two foreign exchange students headed back home to Spain and Sweden on Sunday.
"We have a girl that left for Sweden this morning, and I know that she wasn't aware, either," Holt said. "But for them? You know, they're not so concerned about it. We, as Americans, we are."
While it may not be top of mind, many travelers for now are least taking a moment to think about the threat that remains.
