Security is heightened at most of the airports across the U.S. as a big holiday travel weekend approaches.
FOX's Jeff Monosso has more from O'Hare International Airport:

(Woman) "It gets everybody nervous, but I think it brings security and safety all together. There's lots of things happening all over the world, you can't be discouraged."
