⚖️ 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.

Decision Threshold: 100 ml (3.4 oz) or smaller container + 1 clear quart bag per passenger.

⚠️ Common Traveler Mistake to Avoid

The Mistake: Carrying multiple quart bags per traveler or forgetting that pastes and gels (toothpaste, hair gel, lip gloss) count as liquids.

How to Avoid It: Consolidate all toiletries into one quart bag per traveler or transition to solid alternatives (shampoo bars, solid deodorant).

How to Pack Liquid & Roll-On Deodorant for a Flight

Solid stick deodorants are not liquids and do not take up space in your 3-1-1 bag. Always verify specific airline carry-on size limits and pack delicate items securely to prevent baggage damage during transit.
