If you're thinking about carrying your luggage on the plane on your next trip, you may want to make sure you're up on the rules.
TSA officer Shekia Gay says just remember 3-1-1.
Three basically is the ounce size of the containers themselves which is 3.4 ounces or less; the one being the one-quart size clear resealable zip-top bag and one also is per passenger.
But Gay says that despite the simple rule, there are exceptions that often stump travelers.
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.
Anything medically necessary can actually be above the 3.4-ounce size limit, but those items are subject to additional testing.
"We have to do that just to ensure that its not anything toxic," Gay said.
Gay says one of the biggest offenses as far as liquids are concerned are drinks, juices and bottled waters.
