When you are packing for a Delta Air Lines flight, you might start to wonder: What liquids can I bring in my carry-on or checked baggage? The Delta Airlines Liquid Policy works directly in alignment with TSA security screening for all passengers departing from U.S. airports. Generally, every liquid, gel, cream, paste, or aerosol container in your standard carry-on must be 3.4 ounces (100 ml) or less, packed inside a single clear, quart-sized, re-sealable plastic bag per traveler.
Larger liquids must typically be placed in checked luggage. However, crucial exceptions exist for medically necessary liquids, prescription drugs, breast milk, baby formula, and infant supplies. This comprehensive 2026 guide covers everything you need to know to pass TSA security hassle-free.

What Is the Delta Airlines Liquid Policy for Carry-On Bags?
The Delta Liquid Policy for Carry-On Bags extends TSA's liquid, gel, cream, paste, or aerosol policy to include any products that can flow, spread, spray, or pour.
General guidelines to follow:
- Regular liquid items must be no more than 3.4 oz (100 ml) per bottle.
- All liquid items must be contained in a transparent, easy-to-clean, quart-size clear zip-top bag.
- The rule applies to everyday personal care products such as shampoo, conditioner, lotion, sunscreen, toothpaste, perfume, cologne, liquid makeup, hair gel, shaving cream, hand sanitizer, and aerosol toiletries.
- Generally, larger domestic containers must be stowed in checked luggage.

- Note: The final determination of whether an item passes security rests with the TSA officer at the checkpoint.
How Much Liquid Can You Bring on a Delta Carry-On?
At airport TSA checkpoints, the standard limit for carry-on liquids is strictly 3.4 ounces (100 ml) per container.
| Restriction Parameter | Standard Carry-On Limit | Key Guidelines |
|---|---|---|
| Container Volume | 3.4 oz (100 ml) max | Capacity printed on bottle determines compliance, not fluid level. |
| Liquids Bag Size | 1 Quart (1 Liter) Bag | Must be transparent, clear, and easy to zip completely shut. |
| Bag Allowance | 1 Bag per Passenger | Must fit all your standard liquids without bulging or tearing. |
| Covered Item Types | Liquids, Gels, Pastes, Aerosols | Includes toothpaste, creams, deodorants, food pastes & cosmetics. |
| Medical & Baby Fluids | Exempt from 3.4 oz Limit | Must be declared to security agents before screening. |
Pro Tip: Always make sure containers fit comfortably inside the quart-sized bag so the zip seal closes effortlessly.
Does Delta Airlines Follow the TSA 3-1-1 Liquid Rule?
Yes. Delta Airlines fully adheres to the Transportation Security Administration (TSA) 3-1-1 liquids directive for all domestic flights and U.S. departures.
Containers must be 3.4 ounces (100 milliliters) or smaller.

What Is the Delta Airlines Toiletries Carry-On Policy?
Personal hygiene products follow standard TSA restrictions when entering checkpoint screening.
Best practices for packing toiletries on Delta:
- Check Printed Capacity: TSA inspects the maximum volume printed on bottle labels, regardless of how full the bottle actually is.
- Use Tight Lids & Caps: Prevent pressure leaks during flight by using leak-proof travel bottles.
- Easy Access Placement: Store your clear liquids bag at the top of your carry-on bag so it can be quickly extracted if TSA officers request it.
- Switch to Solid Toiletries: Use solid deodorant sticks, bar soap, or powder products to reduce the overall count of liquids.
Which Liquids Are Not Allowed in a Delta Carry-On?
Delta Carry-On Liquid Restrictions apply stringently to hazardous items. Flammable, corrosive, or explosive liquids are completely banned in both carry-on and checked luggage.
⚠️ Strictly Prohibited Hazardous Liquids
Warning: Hazardous materials that are forbidden in carry-on luggage cannot be checked in either. Always verify FAA hazardous material guidelines before travel.
Can You Bring Medication Above 3.4 Ounces on Delta?
Yes. Medically necessary liquids, prescription solutions, eye drops, saline, and cough syrups are exempt from the standard 3.4-ounce (100 ml) liquid limit on Delta Air Lines.
Guidelines for traveling with liquid medications:
- Declare Early: Inform the TSA officer at the start of screening that you are carrying medically necessary liquids.
- Separate Inspection: Do not force medically necessary liquids inside your regular 3-1-1 quart bag; present them separately.
- Additional Screening: Be prepared for officers to open containers or test vapors.
- Documentation: While prescriptions or doctor notes are not strictly mandated by TSA for all medications, carrying documentation speeds up screening.
Can I Bring Baby Formula, Breast Milk or Baby Food on Delta?
Yes! TSA and Delta grant generous exemptions for parents traveling with infants or young children.
Baby formula, breast milk, toddler juice, and liquid baby food in reasonable quantities are exempt from 3.4 oz restrictions.

How Are Liquids Handled in Delta Checked Baggage?
If your toiletries exceed 3.4 ounces (100 ml), place them in your checked luggage. However, FAA safety limits still apply to medicinal and toiletry liquids.
Pack full-sized liquids in sealed, leak-proof bags inside your checked baggage to prevent leaks caused by cabin pressure changes.
📋 FAA Limits for Checked Toiletries & Medicinal Aerosols:
- • Single Container Limit: 500 ml (17 fl oz) maximum capacity per bottle.
- • Total Passenger Limit: 2 Liters (68 fl oz) aggregate total per traveler.
- • Cap Protection: Release valves on aerosols must be protected by caps or safe closures to prevent inadvertent discharge.
Are Duty-Free Liquids Allowed in Delta Carry-On Bags?
Duty-free liquids purchased inside airport terminals after security screening are permitted onboard Delta flights even if larger than 3.4 oz, subject to specific international transit rules:
- Must be packed in a transparent, tamper-evident Secure Tamper-Evident Bag (STEB) sealed at the duty-free shop.
- Keep your original purchase receipt visible inside the bag.
- If you have a connecting flight in another country or airport, you may have to pass security again. Check connecting airport regulations carefully!
What If Your Liquid Is Bigger Than the Allowed Carry-On Limit?
If you inadvertently bring standard liquid containers exceeding 3.4 oz to the security checkpoint, TSA will not allow them into the departure area.
Your available options include:
- Return to the check-in desk to put the item in your checked bag (if time permits).
- Surrender or dispose of the liquid at the security checkpoint.
- Hand the item over to a non-traveling companion outside security.
