The three components of the rule are that each liquid must be in a 3.4-ounce or 100ml container or less (3), all containers must be placed inside one clear quart-sized plastic bag (1), and each passenger is only allowed one bag (1).

The 311 rule restricts liquids, gels, and aerosols in carry-on baggage
The 311 rule, also known as the TSA's liquid limit, restricts the quantity, quality, and packaging of liquids, gels, and aerosols in carry-on baggage. The rule was implemented by the Transportation Security Administration (TSA) in response to post-9/11 concerns regarding potential threats posed by liquids onboard aircraft. The primary aim of the 311 rule is to enhance airport security measures and ensure the safety of passengers, flight crew, and aircraft.
The first '3' in the 311 rule signifies that liquids carried in hand luggage must be in containers no larger than 3.4 ounces or 100 milliliters. This includes liquids of all kinds, such as beverages, creams, and even spreads like peanut butter. The exception is made for baby food and baby items, such as breast milk, formula, juice, and liquid baby food, which are allowed in larger quantities.
The first '1' indicates that all liquids must be placed in a single, clear, quart-sized, resealable plastic bag. This allows airport security officials to easily screen and check the contents of the bag. Each passenger is allowed only one such bag for their liquids.
The last '1' signifies that each traveler is permitted only one bag to carry their liquids. This ensures a smooth and efficient travel screening process. By combining all liquids in a single bag, travelers can conveniently navigate security checks without the hassle of standing in long queues.
It is important to note that the 311 rule does not apply to liquids deemed "medically necessary." The TSA allows passengers to bring liquid medication in "reasonable quantities" if they need to be consumed during the flight or at the destination. This exemption includes prescribed medications, contact lens solutions, instant hot or cold packs, liquid vitamins, and other similar items. Additionally, travelers can bring travel-size bottles of alcohol (less than 3.4 ounces and no more than 70% alcohol content) in their carry-on baggage.

Only one quart-sized, clear, resealable bag is allowed
The 3-1-1 rule implemented by the Transportation Security Administration (TSA) governs how much liquid travellers can carry in their carry-on bags during their flight. The rule was introduced to reduce the risk of potential threats such as explosives or flammable substances that can cause harm to passengers. The second numeral '1' in the 3-1-1 rule signifies that travellers can carry only one quart-sized, clear, resealable bag to hold their liquids. This bag must be transparent, which makes it easy for airport officials to check its contents. Each liquid must be in a 3.4-ounce or 100ml container, and all containers must be placed inside this one bag.
The 3-1-1 rule is an important regulation that all travellers must follow. Understanding and adhering to this rule can make the security screening process faster and more seamless. It is also important to note that the liquid limit regulations can change at any time based on situations, so travellers must stay updated with the latest information.
The 3-1-1 rule applies to liquids, gels, and aerosols in carry-on baggage while going through security checkpoints. This includes items such as alcoholic beverages, baby food, canned foods, and even live lobsters. Travellers are advised to check the TSA website for a complete list of all items that are forbidden and permitted through TSA security checkpoints at airports.
It is worth noting that there are some exemptions to the 3-1-1 rule. For example, parents carrying breast milk or formula, or travellers with liquid medication, are afforded some leniency. Anything liquid deemed "medically necessary" is generally exempted from the 3-1-1 rule, according to the TSA. This includes items such as contact lens solutions, instant hot or cold packs, and liquid vitamins.

Each liquid must be in a 3.4-ounce or 100ml container
The 3-1-1 rule implemented by the Transportation Security Administration (TSA) governs how much liquid travellers can carry in their carry-on bags. The rule was implemented to bolster airport security measures, particularly in response to post-9/11 concerns regarding potential threats posed by liquids onboard aircraft. The rule also aims to reduce the risk of potential threats such as explosives or flammable substances that can harm passengers.
The first number '3' in the 3-1-1 rule signifies that each liquid must be in a container that is 3.4 ounces or 100ml in volume. Liquids, gels, and aerosols must be in containers that do not exceed 3.4 ounces or 100ml. This includes items such as alcoholic beverages, baby food, and canned foods. Even non-liquid items with a creamy or spreadable consistency like peanut butter fall under this rule and must adhere to the specified volume limit.
The rule applies to all liquids carried in carry-on luggage and is strictly enforced by TSA officers to ensure the safety of all travellers. It is important to note that this rule does not apply to checked baggage, and travellers can bring larger liquid items in their checked bags if necessary. However, there are certain exemptions to the 3.4-ounce limit for specific items deemed medically necessary.
For travellers who require liquid medication due to a health condition, the TSA allows these liquids in "reasonable quantities" as long as they are needed during the flight or upon reaching the destination. This exemption includes prescribed medications, contact lens solutions, instant hot or cold packs, liquid vitamins, and other similar items. Parents carrying breast milk or formula for their infants are also afforded leniency, and these liquids are exempted from the 3.4-ounce restriction.
By understanding and adhering to the 3-1-1 rule, travellers can ensure a smooth and hassle-free security screening process at the airport. It is advisable to stay updated with the latest regulations, as liquid limit regulations can change at any time based on evolving security situations and requirements.

Exemptions include baby food, medication, and baby formula
The 3-1-1 rule implemented by the Transportation Security Administration (TSA) outlines the quantity, quality, and packaging of liquids that travellers can carry in their carry-on bags. The rule was introduced in 2006 after British officials foiled a plot to detonate liquid explosives on board international flights headed to the US.
The rule's designation of 3-1-1 refers to the three conditions: liquids must be in containers of 3.4 ounces (100 milliliters) or smaller; these containers must fit into a single, clear, quart-size bag; and only one bag is allowed per passenger. Liquids that fall under this rule include gels, aerosols, creams, and pastes.
However, there are exemptions to the 3-1-1 rule, including baby food, medication, and baby formula. Baby food in liquid form, such as purees, is allowed on board without needing to be in a tiny container. Formula, breast milk, and juice for babies are also exempt, and any accessories required to cool these items, such as ice packs, freezer packs, and frozen gel packs, are allowed in carry-on bags.
Additionally, travellers whose medications come in liquid form are afforded leniency. Medically necessary liquids are exempt from the 3-1-1 rule, including prescription medication, liquid medications, and hydration or nutritional supplements for chronic conditions or disabilities. While the TSA does not require a doctor's note, documentation can help expedite the screening process, especially for less common items.
