Wednesday afternoon, the Department of Homeland Security called for more security at overseas airports providing direct flights to American airports like DFW.
According to the Associated Press, there is concern terror groups may be trying to form a bomb that could get through security.
At DFW International Airport, home to 55 international carriers, there are 1,600 to 1,800 domestic and international fights every day.
Passengers at Terminal D, the international terminal, said they wouldn't mind longer wait lines if it meant secure skies.
"I think it's absolutely necessary, when it's that many lives in danger; I absolutely support it," said passenger Kristin Lafferty.
Ruth Peters is flying home to Australia tonight. She agrees a boost to security would be helpful.
"The more security, the better, most of my family has been in the Army over the years, you know? You've got to have security," she said.
In a statement by Secretary Jeh Johnson:
DHS continually assesses the global threat environment and reevaluates the measures we take to promote aviation security. As part of this ongoing process, I have directed TSA to implement enhanced security measures in the coming days at certain overseas airports with direct flights to the United States. We will work to ensure these necessary steps pose as few disruptions to travelers as possible. We are sharing recent and relevant information with our foreign allies and are consulting the aviation industry. These communications are an important part of our commitment to providing our security partners with situational awareness about the current environment and protecting the traveling public. Aviation security includes a number of measures, both seen and unseen, informed by an evolving environment. As always, we will continue to adjust security measures to promote aviation security without unnecessary disruptions to the traveling public.
