In 2006, the Transportation Security Administration or TSA placed a directive to agents and passengers to comply with the “3-1-1” rule for liquids. People boarding planes can carry 3.4 ounces of liquid or 100 ml per container in a 1-quart bag, with one bag per passenger.
This was introduced after a terrorist plot was uncovered by the British Police to detonate liquid explosives carried on board of seven airliners travelling from United Kingdom to the United States of America and Canada. This is popularly known as the "2006 Transatlantic Aircraft Plot". This eventually led to tighter airport security measures everywhere around the world and is currently observed and being implemented.
A British man from Birmingham was believed to be the mediator. Police found a powdered orange soft drink along with a large number of batteries in his suitcase which caused alarm among authorities. They later discovered that the culprits were planning to detonate self-constructed bomb-devices using drinking bottles on the plane.
While the protocol is not convenient and has lent itself to a lot of criticism, arguments and mockery, Intelligence Agencies believe they have an essential reason for implementing it. As its main purpose is our welfare and safety specially while on board, we might as well just follow the said regulations.
Here are the TSA guidelines for carrying liquids on planes from their website (https://www.tsa.gov/travel/security-screening/liquids-rule).
1. You are allowed to bring a quart-sized bag of liquids, aerosols, gels, creams and pastes in your carry-on bag and through the checkpoint.
2. These are limited to travel-sized containers that are 3.4 ounces (100 milliliters) or less per item.
3. Placing these items in the small bag and separating from your carry-on baggage facilitates the screening process.
4. Pack items that are in containers larger than 3.4 ounces or 100 milliliters in checked baggage.
Any liquid, aerosol, gel, cream or paste that alarms during screening will require additional screening.
Common travel items that must comply with the 3-1-1 liquids rule include toothpaste, shampoo, conditioner, mouthwash and lotion. Exemptions are Medications and Infant and child nourishment such as milk formula and breast milk.
TSA’s 3-1-1 limit for carry-on liquids require travelers to be practical, so pack smartly and keep it light. If you are planning to bring with you on a flight your favorite shampoo, contact lens solution or your essential oils on your next holiday trip, make sure to pack them properly to get them through security checkpoints hassle-free. You can either start buying travel-sized bottles of your favorite products or just buy 3 ounces of empty travel-sized bottles which you can fill with your must-have liquids. Make sure you pack these bottles inside a quart-sized clear bags or ziplocks which are sealed. Four or Five bottles may fit in 1 bag.
There are a lot of travel bottles and quart sized clear bags that you can purchase from home good stores, supermarkets or online stores like Amazon which are approved by TSA to help you on deciding on what to bring and what's not allowed to have a more enjoyable and fun-filled travel experience and memories.
