Tonight, the biggest test for the nation's airport they've ever faced. The mad-rushed home from the holiday, leading to what's predicted to be the biggest air travel day in American history. Hopefully, we can get through this line and get to our gate pretty quickly. Nearly three million people set to take to the skies today.

I'm sure TSA has their hands full today. So as we make our way around the corner, we're like crossing our fingers that it'll be calm.

The numbers are daunting. Atlanta's airport saw 30,000 passengers before 9:00 a. M. Everything went so smooth. Today, Los Angeles International Airport projected up to 230,000 travelers. Nasty weather swept across the Midwest, delaying hundreds of flights in Chicago. Nationwide, delays topped 4,000, but cancelations, less than 50.

There is going to be some snow on the roadways.

14 million were under winter weather alerts today, from Iowa to Maine. On the roads, snow, ice, causing accidents across Kansas. But in the air...

Today's a big day in the travel industry, and I think it's a little bit of a victory lap for the industry because everything this holiday travel season has gone smoothly, even with a couple of storms thrown in the mix.

Tsa has seen seven of its 10 busiest travel days on record this year without the major nationwide meltdowns we saw last year.

They staffed up appropriately, and I think that's the biggest thing in getting such a mass amount of people through the airport.

Marisa, so much good news. She's had BWI tonight. Is the rush over after tonight?

Not quite. Some airports like Atlanta are still seeing their peak through 9:00 PM. For folks in the Midwest, the winter weather today is still slowing things down. But don't expect things to be fully back to normal by tomorrow. Aaa says Monday is still a busy day for air travel. Kate.
