⚖️ 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.

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

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).

💧 3-1-1 liquids rule checker

One quart-size (≈1 L) bag per passenger; every container must be 3.4 oz (100 ml) or less.

Fit is approximate — container shape decides real-world packing. Medically necessary liquids and infant food are exempt: declare them. Packing a whole bag? Plan it container by container →

How to Pack Deodorant for a Flight

The trick nobody exploits: a solid-stick deodorant is not a liquid at all, so the jumbo sport stick sails through outside your quart bag. Only sprays, gels, and roll-ons count against it. In checked bags aerosols share one family-size FAA allowance with your hairspray and shaving cream.
