There are strict regulations surrounding what you can and cannot pack in your carry-on and checked luggage.

Whether you're planning for a long weekend in Austin or you're jetting off on a two-week romp through Asia, you want to make sure you meet these rules so you don't find yourself held up at airport security.

To ease the stress of packing — and make your next airport experience a little less stressful — the Transportation Security Administration (TSA) shared the top five items they get asked about the most in a recent blog post. From razors to deodorant, here's what they want you to know when you plan to bring these must-have travel items on vacation.


According to the TSA, certain types of razors are permitted on board while others are not. Disposable razors, replacement blades, and electric razors can go in either your carry-on or checked baggage; if you have a safety or straight razor, you can pack it in your carry-on — but you must remove the blades first and pack them in one of your checked bags.


Luckily, in our tech-centered age, you can pack a wide range of batteries and battery chargers in your carry-on bag. TSA allows dry cell alkaline (e.g. AA, AAA), dry cell rechargeable, lithium ion, consumer-sized lithium ion, and lithium metal batteries — all of which power cell phones, digital cameras, camcorders, laptops, and other small, personal electronics. You can also bring up to two larger lithium ion batteries; should you need one that is between 101 and 160 Watt-hours, you will need to get the airline's approval beforehand.

Lithium batteries, portable chargers, external battery chargers, and power banks cannot go in checked luggage, so you must take them with you. All other batteries permitted on board may be checked, but TSA advises that you pack them in your carry-on in case there's a fire and the cabin crew needs access to them.

On the other hand, car batteries, wet batteries, and spillable batteries are banned from flights. If you need one of these types of batteries for a scooter or wheelchair, however, you can bring it as long as you let the aircraft operator know.

For more information about batteries, contact the Federal Aviation Administration (FAA).


There are no limits when it comes to solid and powder makeup; you can pack as much — or as little — as you want in either your carry-on or checked luggage.

However, if you want to pack liquid, lotion, gel, paste, or creamy makeup, it must be stored in containers that are 3.4 ounces or less, and all the containers combined must fit inside a single quart-sized zip-top bag. Makeup that cannot fit in the liquids bag can be checked.

Shampoo and Deodorant

The same rules that apply to liquid makeup also apply to shampoo, conditioners, and deodorant. Shampoo, conditioner, and roll-on, aerosol, and gel deodorant must be travel-sized and fit in one quart-sized, zip-top bag to meet carry-on bag requirements. If the containers are larger than 3.4 ounces, you will need to pack them in your checked luggage.

If you prefer solid or powder deodorant, you may pack it in your carry-on without storing it in your liquids bag.
