Right now there are signs posted all over the Louisville airport notifying passengers the terror threat level is at orange, the second highest level for homeland security.
For the first time since a suicide bomber attempted to blow up a jet on Christmas Day, President Obama is alerting the nation that more changes are coming to how you fly.
President Barack Obama said, "When a suspected terrorist is able to board a US plane with explosives on Christmas Day the system has failed in a potentially disastrous way."
He met with his national security team Tuesday to try and figure out how that suspected terrorist was able to board Northwest Airlines Flight 253.
Obama said, "The bottom line is this: The US government had sufficient information to uncover this plot and potentially disrupt this Christmas Day attack. But our intelligence community failed to connect those dots."
And he vowed to make changes to improve intelligence and security. At Louisville International Airport, travelers have noticed the tighter security.
Pamela Webber said, "They do extra checks they're frequently checking bags."
Obama says, "In the days ahead I will announce further steps to disrupt attacks including better integration of information and enhanced passenger screening for air travel."
But how much screening is too much? There has already been an increase in the number of air marshals on planes, more explosive detection teams and enhanced screening for passengers traveling from 14 nations with ties to terrorism.
And then there are these, body scanners, designed to provide detailed images under a person's clothing.
They're in 19 US airports now and Tuesday, Canada announced that they're buying 44 scanners for their airports.
The scanners are not at Louisville's airport now, but there is support to bring them here and to every airport in the United States.
Kimi Rakes said, "I think safety is more of an issue than privacy so I would say whatever it takes in order that the plane is secure."
Ralph Musen said, "Doesn't bother me, not a problem."
Rufus Bruno said, "I don't mind it at all. Anything for secuirty as far as I'm concerned."
But there are privacy concerns with the explicit images.
Pamela Webber said, "I don't think that's right. I don't think that we should be subjected to anything like that. It's kind of an invasion of privacy and our personal space and such."
There are not any plans right now to require every US airport and passenger to use these body scanners.
But the TSA has said that they plan to buy an additional 300 scanners for US airports this year.
