⚖️ 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.

Flying internationally? Security follows the country you depart from — the authority above applies at your departure airport. Customs at arrival is separate.

🔍 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

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 Baby Powder for a Flight

The Canada trap: baby powder has no exemption from CATSA’s total powder cap even though baby food and formula have one — a family with formula, powder, and protein powder can overflow 350 ml fast. Travel-size it in the cabin and let the family-size bottle ride in the hold.
