⚖️ 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).

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 Hairspray for a Flight

The “but it is not a liquid” argument loses: aerosols count against the liquids bag, cap first. For the hold, tape nothing — the original cap clipped firmly over the actuator is what the FAA asks for, plus a zip bag so a leak does not perfume your clothes.
