HOUSTON – While packing your suitcase for your trip, there are different rules for what you can put in your carry-on luggage and what you can pack in your checked luggage.

First, let’s understand the difference between a carry-on suitcase and checked luggage.

A carry-on is anything that actually goes through TSA security with you and is physically carried to your seat on the plane. These can be roller bags, backpacks, or even purses.

Checked luggage is anything that goes underneath the airplane. You drop off these bags and items at the airline ticket counter when you get to the airport.

One of the quickest ways to derail your trip before it even starts is to pack something in your carry-on that isn’t allowed.

“We often hear. I didn’t know it was in my bag or I forgot it was there When you find a prohibited item,” said TSA Spokesperson Patricia Mancha.

The biggest one is liquids. You cannot take any liquids more than 3.4 ounces on the airplane in your carry-on luggage.

“If you can spell it, spray it, pour it or pump it. It’s considered a liquid and limited to 3.4oz.,” Mancha explains. “A great way to think about it is that you can bring all the potatoes you want in your carry-on luggage. Once they become mashed potatoes, it’s a liquid and limited to 3.4oz.”

If you bring liquids larger than 3.4 o.z., you will either have to check the bag, surrender the item to the TSA or throw it out.

While you won’t get in trouble for bringing liquids in your carry-on, you could end up in handcuffs if you bring a firearm in any carry-on.

“You can travel with a firearm, but it must be unloaded, packed in hard inside a container and declared with your airline in your checked luggage,” Mancha explains. “At no time are you to bring a firearm, any firearms components, including ammunition, in your carry-on. If it is, then you’re subject to fines of up to $15,000 and you’re subject to fines of up to $50,000 and will not be allowed to participate in TSA precheck and not get a refund.”

There are a lot of rules for what you can take in a carry-on or in a checked bag. For the full list from the TSA, visit their website.
