The "3-1-1 rule" is a security regulation implemented by the Transportation Security Administration (TSA) for carry-on luggage regarding liquids, gels, and aerosols.
TSA's 3-1-1 Rule Explained
The TSA's 3-1-1 rule focuses on the restrictions of carrying liquids and similar items on airplanes. It's designed to ensure flight safety by limiting the quantity and method of packing these items. Here's a breakdown:
- 3: Liquids must be in containers of 3.4 ounces (100 milliliters) or less. This is the first "3" in the 3-1-1 rule.
- 1: All of your liquid containers must be placed in one clear, quart-sized plastic bag. This is the second "1" in the 3-1-1 rule.
- 1: Each passenger is allowed one clear, quart-sized plastic bag of liquids. This is the final "1" in the 3-1-1 rule.
Key Aspects of the 3-1-1 Rule
Container Size
- The container itself must not exceed 3.4 ounces (100 milliliters). It's not just about how much liquid is inside; the container size is crucial.
Clear Plastic Bag
- The bag holding the liquid containers must be transparent, allowing TSA agents to easily inspect contents.
- It must be a quart-sized bag. Standard zip-top bags often fit this requirement, like those that are commonly used for food storage.
- The bag must be sealed. If it can't seal, it may be a reason for confiscation.
Items Included
- The rule applies to liquids, gels, creams, pastes, and aerosols, such as:
- Shampoo and conditioner
- Lotions
- Toothpaste
- Mouthwash
- Liquid foundations and concealers
- Gels such as hair gel
- Aerosols such as hairspray and deodorant
- Peanut butter
- Cream cheese
- Jellies and jams
Exceptions
- There are some exceptions to the rule, including:
- Medically necessary liquids, such as baby formula, prescription medications (with proper documentation) and breast milk, can be taken in larger quantities, but are subject to inspection.
Practical Tips
- Prepare in Advance: Pack your liquid items well before your flight to avoid any hold-ups at security.
- Check for Travel Sizes: Many personal care products are sold in travel sizes that meet the 3.4-ounce requirement.
- Pack Smart: Don't pack unnecessary liquids in your carry-on. If you can pack them in your checked baggage, do so.
