The Transportation Security Administration’s (TSA) carry-on rules are no doubt confusing and what’s worse is they continue to evolve and change. Here are 5 TSA carry-on rules that I bet you didn’t know!

--> You can bring booze in your carry-on.  The TSA allows you to bring as many 3.4-ounce bottles of liquid that can fit in one quart-sized clear plastic zip-top bag. You may carry as many 3.4-ounce bottles of liquid (mini bottles of liquor are 1.7 ounces) that fit comfortably in one, quart sized, clear plastic, zip-top bag. Comfortable means that the bag will seal without busting at the seams. One bag is permitted per passenger.  Liquids (including alcohol) purchased after clearing the security checkpoint are permitted on the aircraft.  However, FAA regulations state that “No person may drink any alcoholic beverage aboard an aircraft unless the certificate holder operating the aircraft has served that beverage.”  For your Checked Baggage - Any amount of alcohol greater than 3.4 ounces must be packed in checked baggage.  For more precise information visit TSA’s website.

-->You can put deodorant in your carry-on! Stick deodorants of any size are allowed. Powders and crystals are good to go as well.  Spray, Gel, Liquid, Cream, Pastes, and Roll-On deodorants need to be in containers no larger than 3.4 ounces and placed in a clear quart-sized baggie.  Or, you always have the option of placing deodorant in your checked baggage if you’re checking a bag.

-->Electric and disposable razors; Good-to-Go. Straight and safety razors; No Way!  There is a lot of confusion on what types of razors are OK to take with you in your carry-on baggage. Let’s just start by saying that electric razors are OK, but straight razors are a no-go.   Disposable razors and their replacement cartridges can be in a carry-on, as well as electric razors.

-->E-cigarettes [and other Nicotine Delivery Systems] -  TSA advises that these devices are permitted on planes, but the FAA recently notified airlines that the lithium batteries used in these devices are fire hazards and should not be packed in checked baggage and may only be carried in the aircraft cabin (in carry-on baggage or on your person). They may not be used or charged on the aircraft.  When a carry-on bag is checked at the gate or planeside, all electronic cigarette and vaping devices, along with any spare lithium batteries, must be removed from the bag and kept with the passenger in the aircraft cabin.

-->Packing batteries. Dry cell alkaline, rechargeable batteries and lithium batteries should be packed in your carry-on and NOT in your checked baggage. TSA recommends packing all types of batteries in carry-on luggage whenever possible. And there are some types of batteries that are prohibited unless they’re being used to power a scooter or wheelchair. So if you have any doubts on what batteries are ok, check out TSA’s battery tips for packing tips for batteries, prohibited batteries and battery chargers.
