⚖️ Why This Rule Exists: International 3-1-1 Liquid Security Rules & Container Geometry
Containers with a marked capacity of 100 ml (3.4 oz) or less that fit within a single clear, resealable 1-quart (1-liter) plastic bag are permitted through screening because small volumes can be rapidly inspected and present limited hazard potential.

Conditions, Warnings & Legal Exceptions
🛍️ Duty-free purchases
Duty-free liquor in the sealed tamper-evident bag (STEB) with receipt is allowed in the cabin, including through one connecting security checkpoint, typically within 48 hours.
How Many Alcohol / Liquor Can You Bring on a Plane?
Limited to what fits inside a single 1-quart (1-liter) transparent resealable bag in carry-on.
Official regulatory posture: Where aviation authorities publish no individual numeric cap, standard carry-on dimensional and weight limits govern. Screeners retain statutory discretion to inspect bulk quantities.
🔍 Security Checkpoint & X-Ray Screening Advice
Place your clear 1-quart bag in the screening bin outside your luggage in 2D X-ray lanes. In 3D CT scanner lanes, keep it inside your bag unless instructed otherwise by the screening officer.

⚠️ Common Traveler Mistake to Avoid
How to Avoid It: Consolidate all toiletries into one quart bag per traveler or transition to solid alternatives (shampoo bars, solid deodorant).
Does Alcohol / Liquor Need to Be Declared at the Airport?
Standard toiletries and liquids conforming to the 3-1-1 rule (containers under 3.4 ounces / 100 ml inside a clear quart bag) require no separate declaration. You simply place the bag in a screening bin. Medically necessary liquids exceeding 3.4 ounces must be verbally declared to checkpoint screeners before inspection.
What Happens if Alcohol / Liquor Is Confiscated or Non-Compliant?
If liquid containers exceeding 3.4 ounces (100 ml) are detected in carry-on baggage without an infant or medical exemption, screeners will not allow them past security. Travelers must surrender the item for destruction, return outside security to place it in checked luggage, or mail it home.
Test Container Size in the 3-1-1 Liquids Planner
Check if your container capacity passes checkpoint screening or if it must be decanted into a compliant bottle.
