Introduction
Air travel is often associated with long lines, strict regulations, and tedious security checks. One of the biggest concerns for travelers is navigating the restrictions for bringing liquids on a flight. Knowing what you can and cannot bring on board an aircraft can make all the difference when it comes to having a comfortable and stress-free travel experience.
In this article, we’ll discuss the basics of airline liquid regulations and provide comprehensive guidance on how much liquid you can take on a flight. We’ll also share some tips and tricks for packing and flying with liquids safely.

Overview of Liquid Regulations for Air Travel
The U.S. Transportation Security Administration (TSA) is responsible for enforcing security regulations at airports and other transportation hubs. According to the TSA, “all liquids, aerosols, gels, creams, and pastes must be in containers three ounces or smaller and placed inside one clear quart-sized bag per passenger.” These rules are commonly referred to as the 3-1-1 rule.
The 3-1-1 rule applies to all passengers who are flying within the United States, regardless of their destination. It is important to note that international flights may have different regulations, so be sure to check with your airline prior to your departure.
Comprehensive Guide to Airline Liquid Regulations
The 3-1-1 rule is just the beginning when it comes to understanding airline liquid regulations. Let’s take a closer look at the types of liquids you can bring on a plane, and the maximum amount of each type that is allowed.
Overview of TSA Guidelines
The TSA has a list of items that are prohibited from being carried on an aircraft. This includes any liquids that do not meet the 3-1-1 rule. Items such as aerosols, gels, creams, and pastes must be in containers three ounces or smaller and placed inside one clear quart-sized bag per passenger.
Types of Liquids Allowed on Flights
Not all liquids are created equal when it comes to air travel. The TSA has specific regulations regarding the types of liquids that can be brought on a flight. Generally speaking, the following types of liquids are permitted:
- Water and other non-alcoholic beverages
- Juice boxes and juice pouches
- Milk and formula
- Coffee, tea, and other hot drinks
- Alcoholic beverages
- Personal care and hygiene products (e.g. shampoo, conditioner, lotion, etc.)
- Medicines and medical supplies
- Food items (e.g. soup, sauces, salad dressing, etc.)
Maximum Volume Limits
In addition to the types of liquids allowed on flights, there are also restrictions on the maximum volume of each item. According to the TSA, “the maximum volume for a single container is 3.4 ounces (100 milliliters).” However, larger containers of certain items may be permitted if they are marked with an “approved” sticker. For example, baby formula and breast milk are allowed in containers up to 12 ounces.
How to Pack Liquids in Carry-on for Air Travel
Now that you know what types of liquids are allowed on a flight, let’s take a look at how to properly pack them in your carry-on. Here are the steps for ensuring your liquids are secure and compliant with TSA regulations:
- Place all liquids in a single, clear quart-sized bag.
- Ensure that each container has a maximum volume of 3.4 ounces (100 milliliters).
- Securely seal the bag and place it in an easily accessible location in your carry-on.
- Keep the bag in your possession throughout the duration of the flight.
Tips for Making Sure Your Liquids are Secure
In addition to following the steps outlined above, there are a few other tips you can follow to ensure your liquids are secure and compliant with TSA regulations:
- If you have a large bottle of liquid (more than 3.4 ounces), transfer it into a smaller container before packing it in your carry-on.
- Check the expiration date on any liquid items you plan to bring on the plane.
- If possible, store any fragile liquids in a hard-sided container to prevent spillage.
- Label all containers clearly with their contents.

Tips and Tricks for Flying with Liquids
Now that you know how to pack your liquids in your carry-on, let’s take a look at some tips and tricks for flying with them safely. Here are some strategies for minimizing the risk of damage or spillage:
- Pack your liquids in a designated area of your carry-on, away from any electronics or fragile items.
- Store any liquids that require refrigeration in an insulated bag with a cold pack.
- Keep the quart-sized bag containing your liquids in an outside pocket of your carry-on for easy access during security screenings.
- If possible, keep a spare bag of liquids in your checked baggage in case your primary bag is lost or damaged.
Alternatives to Bringing Liquids on a Flight
If you’re concerned about the risk of spilling or damaging your liquids while flying, one option is to purchase them after you arrive at your destination. Most airports and hotels offer a variety of personal care and hygiene products that can be purchased at a reasonable price.
