Traveling by air can be stressful, and understanding the Transportation Security Administration (TSA) rules, especially those concerning liquids, is crucial for a smooth airport experience. If you’re wondering “How Much Liquid Can You Fly With,” you’re not alone. The TSA’s 3-1-1 rule for carry-on liquids is well-known, but it’s also important to understand the exceptions. This guide will clarify the rules and help you pack your liquids with confidence.
The standard TSA 3-1-1 rule dictates that for carry-on baggage, you are limited to liquids in containers of 3.4 ounces (100 milliliters) or less, all placed in one quart-sized, clear, plastic zip-top bag. However, this rule isn’t a blanket restriction. There are several exceptions for essential liquids, allowing you to bring larger quantities of certain items onboard. Knowing these exceptions can save you time and hassle at security checkpoints.
Medically Necessary Liquids: What’s Allowed?
For passengers traveling with medical needs, the TSA makes allowances for “medically necessary liquids, gels, and aerosols.” This is a significant exception to the standard 3.4-ounce rule. If you require liquid medications, contact lens solution, or other medical liquids in quantities exceeding 3.4 ounces, you are permitted to bring them in your carry-on.
Liquid Medications and Contact Lens Solution
Whether prescription or over-the-counter, liquid medications are exempt from the 3.4-ounce limit when deemed medically necessary. This includes solutions, gels, and aerosols. Similarly, contact lens solutions also fall under this exception. It’s advisable to declare these items to TSA officers at the security checkpoint for smoother processing.
If you prefer to avoid X-ray scanning or opening your medication, you can inform the TSA officer. In such cases, “additional steps will be taken to clear the liquid and you or the traveling guardian will undergo additional screening procedures, which may include AIT screening, a pat-down, and screening of your carry-on property,” according to TSA guidelines.

It’s important to note that while prescription wet pet food is considered a liquid, it does not qualify for the medically necessary liquid exception, even for service animals.
Traveling with Infants: Breast Milk and Baby Formula
Parents traveling with babies have specific needs, and TSA regulations accommodate them. Breast milk and baby formula are categorized as “medically necessary liquids,” allowing you to bring quantities greater than 3.4 ounces. This applies even if the child is not present during travel.
To expedite the screening process, the TSA suggests, but does not mandate, transporting these liquids in clear, translucent bottles. This allows for easier screening using Bottle Liquid Scanners. Liquids in pouches might require additional inspection. While TSA may ask you to open the containers, they assure that nothing will be inserted into the liquid during screening. If you prefer that breast milk or formula not be X-rayed, alternative screening methods are available.

Baby and Toddler Food and Drinks
Beyond breast milk and formula, other food and drinks for babies and toddlers are also permitted in reasonable quantities. This includes puree pouches and even water for babies. These items also fall under the “medically necessary” category, acknowledging the essential needs of young travelers.
Comfort Items for Babies: Liquid Teethers
Recognizing the importance of comfort for infants, TSA specifically allows “liquid-filled teethers” to be brought through security checkpoints. This ensures that parents can soothe their babies during travel without concern about liquid restrictions.
Keeping Items Cool: Ice, Gel, and Freezer Packs
To maintain the required temperature for medically necessary items, ice packs, gel packs, and freezer packs are also permitted, regardless of their state (solid or liquid). Even if melted, these packs are allowed as exceptions. Frozen or slushy items might be subject to further inspection. Additionally, accessories like IV bags, pumps, and syringes related to medical supplies are also allowed.

Unexpected Liquids: Fresh Eggs
Surprisingly, fresh eggs are also permitted through TSA security, despite containing liquid yolks. While not explicitly a liquid exception for medical or infant needs, eggs are allowed in carry-on baggage. However, they might need to be separated from other items for inspection to confirm their contents.
Aquatic Items: Live Fish and Coral
For those transporting aquatic life, TSA makes exceptions for live fish and coral in water, provided they are in clear, transparent containers and undergo inspection. This exception acknowledges the necessity of water for the survival of these items. Some airlines may also allow live lobsters in clear, spill-proof containers.
Scientific and Medical Research: Biological Specimens
In the realm of scientific research, non-infectious biological specimens preserved in solutions like formaldehyde, ethanol, or isopropanol are permitted. However, specific packaging requirements must be met. This includes a maximum of 30 milliliters of free liquid in a heat-sealed inner plastic bag, and no more than one liter in the outer packaging, which must be labeled: “Scientific research specimens, 49 CFR 173.4b applies.”
Powering Devices: Non-Spillable Wet Batteries
Certain portable electronic devices require non-spillable wet batteries. These are allowed as long as they are protected against accidental activation or heat generation, and the battery voltage is 12 volts or less with less than 100 watt-hours.
Souvenirs and Gifts: Duty-Free Liquids
Airport shopping offers a range of liquid souvenirs. These can be brought on board, even if exceeding 3.4 ounces, provided they are purchased from duty-free shops and sealed in a Security Tamper-Evident Bag (STEB) by the cashier. This system, developed by the International Civil Aviation Organization, allows for an exception to liquid volume rules for duty-free purchases.
Key Takeaways for Flying with Liquids
Understanding TSA liquid rules is essential for stress-free travel. While the 3-1-1 rule applies to general carry-on liquids, numerous exceptions exist for medically necessary items, baby-related liquids, and other specific cases. When traveling with liquids that fall under these exceptions:
- Declare them: Inform TSA officers about your liquids at the security checkpoint.
- Be prepared for inspection: Understand that additional screening might be required.
- Pack strategically: Consider clear containers for easier inspection, especially for baby formula and breast milk.
- Know the rules: Familiarize yourself with the specific exceptions relevant to your travel needs.
By understanding these guidelines, you can confidently navigate airport security and ensure you have the necessary liquids with you during your flight. Always check the TSA website (www.tsa.gov) for the most up-to-date information before your travel date, as regulations can change.
