FORT MYERS, Fla.-It's one of the busiest travel weeks of the year. According to AAA about 42.4 million people are flying or driving over the holiday weekend.

As always before you head to the airport always check with your with your airline to make sure there are no delays--- but you can also check out another website. The website from the FAA lets you see delays around the nation and lets you look up your specific airport.

The web site is As you know more travelers are carrying their luggage onto planes these days to avoid costly baggage fees. That makes knowing the rules for bringing aboard liquids, gels and aerosols on board more important than ever.

So just remember 3-1-1 rule. Three stands for three-ounce containers-- technically liquid containers of three-point-four ounces or less are acceptable...

One stands for the one-quart size clear resealable zip-top bag.

And the last "one" means only one bag per passenger. However, there are exceptions to the rules. For example, regular-sized liquid prescriptions and over-the-counter medications like cough syrup are allowed, as well as petroleum jelly and saline solution. But you have to declare these items and those items will be subject to additional testing.
