When traveling by air, understanding the liquid policy is essential for avoiding any issues during security screening. Delta Air Lines, like most major airlines, adheres to the Transportation Security Administration (TSA) regulations for carrying liquids in your carry-on bag. Here’s everything you need to know about Delta’s liquid policy to help make your travel experience smoother and more efficient.

TSA Liquids Rule: The 3-1-1 Rule

Delta follows the TSA’s 3-1-1 Rule for liquids, which applies to all passengers flying in and out of the U.S. and other international flights. Here’s a breakdown of the 3-1-1 Rule:

• 3 ounces or less: Each liquid, gel, or aerosol must be in a container that holds 3 ounces (100 milliliters) or less.
• 1 quart-sized bag: All liquids, gels, and aerosols must fit in a single, clear, resealable plastic bag that can hold up to 1 quart (approximately 1 liter). This bag is typically a sandwich bag or any bag of similar size.
• 1 bag per person: Each passenger is allowed to carry one quart-sized bag with their liquids.

This rule applies to items like shampoos, conditioners, lotions, toothpaste, and other liquid-based products you might want to bring on board.

Types of Liquids Covered by the 3-1-1 Rule

The TSA’s 3-1-1 rule covers a wide range of liquid items, including:

• Shampoos, conditioners, and body washes
• Toothpaste, mouthwash, and other hygiene products
• Liquids for medical or dietary purposes (more on this below)
• Cosmetics such as foundation, makeup remover, and perfumes
• Beverages and bottled liquids (including water, juice, soda, and alcohol)

These items must all be placed inside the quart-sized bag and comply with the size restrictions for liquids.

Liquids for Medical or Special Dietary Purposes

While the 3-1-1 rule applies to most liquids, there are exceptions. Delta allows passengers to bring larger quantities of liquids if they are medically necessary or for special dietary needs. These include:

Prescription medications: Liquid medications are allowed in larger quantities, but you will need to declare them at the security checkpoint. Be sure to bring the prescription or doctor’s note if required.

Baby formula, breast milk, and juice: Parents traveling with infants can carry larger quantities of baby formula, breast milk, or juice. You may need to separate these items from your other liquids and inform the TSA officer during screening.

Dietary liquids: If you have specific dietary requirements that require you to carry liquids such as nutritional supplements or meal replacement drinks, these are generally allowed beyond the 3-ounce limit. Again, you will need to inform the TSA agent at security.

Restrictions on Alcohol and Other Liquids

Alcohol: Alcoholic beverages are allowed in carry-on bags, but they must be in containers of 3 ounces or less, just like other liquids. Additionally, if you're bringing alcohol in quantities greater than 3 ounces, it must be in your checked luggage. Remember, the TSA restricts the quantity of alcohol you can carry based on the alcohol content:

Alcoholic beverages with an alcohol content of 24% or less can be carried in carry-on bags in containers up to 3 ounces.

Alcoholic beverages with an alcohol content between 24% and 70% (e.g., hard liquor) must be in checked luggage, and the maximum amount per person is generally limited to 5 liters.

Alcohol over 70% alcohol content (such as grain alcohol) is not allowed in either carry-on or checked baggage.

Packing Tips for Liquids on Delta Flights

Use travel-sized containers: To avoid the hassle of repacking, make sure all of your liquid items are packed in travel-sized containers of 3 ounces or less. You can buy empty travel-sized bottles to transfer your products into.

Seal liquids carefully: Leaking containers can cause a mess and potentially damage your items. Always check that the cap is tightly sealed before placing liquids in your bag.

Pack your quart-sized bag last: Since you’ll need to remove your quart-sized liquid bag during security screening, it’s a good idea to pack it last in your carry-on for easy access.

Consider alternatives: If you don’t want to deal with liquid restrictions, consider purchasing solid alternatives such as bar soap, solid deodorant, or powder shampoo, which are not subject to the liquid restrictions.

Conclusion

Delta Airlines follows TSA’s standard 3-1-1 Liquid Rule, meaning you can bring liquids in your carry-on bag as long as each container holds 3 ounces or less and all liquids fit in a single quart-sized bag. However, exceptions are made for medical necessities, baby-related items, and certain special dietary liquids. By packing wisely and adhering to the regulations, you can avoid any delays at the security checkpoint and have a smooth experience with your carry-on liquids.
