Travel light
Don't bring toothpaste
Know your rights
Don't bring toothpaste? That's really what they are recommending:
DUMP THE TOOTHPASTE Remember that certain
toiletries and other liquid items are not allowed on flights, which can
lead to frustrating delays at security. Leave that tube of toothpaste
and buy a new one at your destination.
If you are going somewhere where toothpaste is waiting for you then I would agree to leave it so that you aren't carrying extra weight that you don't need. But they are saying that you shouldn't to save time with security. It almost sounds like they are think that toothpaste and other liquid items are not allowed through security. This is incorrect. You can bring liquids through the checkpoint and on the airplane, you just have to know and follow the TSA's rules about size and baggies.
This is what the TSA website has to say about bringing liquids:
Air travelers may carry liquids, gels and aerosols in their carry-on bag when going through security checkpoints.
The following rules apply to all liquids, gels, and aerosols carried through security checkpoints.
- All liquids, gels and aerosols must be in three-ounce or smaller
containers. Larger containers that are half-full or toothpaste tubes
rolled up are not allowed. Each container must be three ounces or smaller.
- All liquids, gels and aerosols must be placed in a single,
quart-size, zip-top, clear plastic bag. Gallon size bags or bags that
are not zip-top such as fold-over sandwich bags are not allowed. Each traveler can use only one, quart-size, zip-top, clear plastic bag.
- Each traveler must remove their quart-sized plastic, zip-top bag
from their carry-on and place it in a bin or on the conveyor belt for
X-ray screening. X-raying separately will allow TSA security officers
to more easily examine the declared items.
There are exceptions for baby formula, breast milk, and other
essential liquids, gels, and aerosols, including prescription and
over-the-counter medicines.
