Travelers we spoke to at the Lubbock International Airport don't seem too worried about the threat level increase.
"I didn't even think about it. It doesn't really scare me. I don't think the public really cares. It just means you have to wait longer at the airport," says Monica Martinez.
"I think it has a lot to do with the holidays, but plus everything that's going on right now," says Angela Massey.
"I think the nation is just like me. It hopes stuff doesn't happen, but if it does, we'll be ready and do what we can to help each other and make it through this time," says Dominic Granado.
LIA Interim Aviation Director John McGinley says they are evaluating their programs and reviewing information given to the airport by the Transportation Security Administration before making appropriate adjustments.
