Storms could impact holiday travel -- what to know

CHICAGO - As we gear up for the holidays, loads of folks are gearing up for some serious traveling—planes, trains, automobiles, you name it.

AAA's guessing that a whopping 115 million people will hit the road for trips reaching at least 50 miles.

That's over a 10-day stretch from now until Jan. 1, and it's about two percent more than last year.

If you're headed to the airport on Friday, brace yourself. O'Hare's surrounded by bumper-to-bumper traffic, and once you're inside, it's a whole different kind of busy.

Flight-wise, there have been about a dozen cancelations at O'Hare, plus a couple more at Midway. Luckily, delays are mostly minimal—both spots are seeing wait times of 15 minutes or less. But the lines? Yeesh. 

Whether you're inside or outside the airports, especially in those security queues, they're something to reckon with.

The TSA's expecting 2.5 million folks to take to the skies every single day until Jan. 2nd. Rain might be coming down now, but the forecast says things might get dicey in the next few days.

"We may see some bad weather impacting travel around Christmas and New Year’s," said U.S. Transportation Secretary Pete Buttigieg. "FAA is working closely with airlines to plan for that possibility."

He said they use weather predictions from the National Weather Service to plot out flight paths through the busiest parts of the sky.

Buttigieg also wanted to make sure everyone knows: if your flight gets axed for whatever reason, you're owed a full refund.

For the estimated 104 million drivers this holiday season, gas prices are starting to go back up. AAA said the national average is up 4 cents from last week. Now a gallon of fuel will cost you on average $3.12.
