The 3-1-1 Rule
When it comes to traveling by plane, one of the most common questions passengers have is about how much liquid they can take on board. The Transportation Security Administration (TSA) has established the 3-1-1 rule, which restricts the amount of liquids, gels, and aerosols that you can bring in your carry-on luggage.
Understanding the 3-1-1 Rule
The 3-1-1 rule means that you can bring liquids in containers that are 3.4 ounces (100 milliliters) or less per item. These containers must all fit into a single quart-sized, clear, plastic, zip-top bag. Each passenger is allowed only one bag, which must be presented separately for screening.
Examples of Allowed Items
- Travel-sized toothpaste
- Lip gloss or balm
- Sunscreen
- Eye drops
Exceptions to the Rule
There are exceptions to the 3-1-1 rule for certain items, such as medications, baby formula, breast milk, and liquids needed for medical reasons. These liquids are typically allowed in reasonable quantities, but you may be subject to additional screening.
Case Study
Emily was traveling with her infant son and needed to bring breast milk on the plane. She was able to bring more than 3.4 ounces of liquid in this case, but she was asked to separate the breast milk from the rest of her carry-on items for inspection.
Statistics on Liquid Confiscations
According to TSA data, in 2019, over 4,000 pounds of liquid items were confiscated at U.S. airport security checkpoints. This includes anything that exceeds the 3-1-1 rule or is considered a hazardous material.
Conclusion
It’s important to familiarize yourself with the TSA’s rules on liquids before you fly to avoid any issues at security checkpoints. By following the 3-1-1 rule and understanding the exceptions, you can ensure a smoother travel experience with your liquids in tow.
