Securing these small vials in quarters with a diameter no greater than 3.4 inches (8.9cm), and ensuring they each fit within their own clear, quart-sized plastic bag, is crucial. This will make inspection at security a breeze.

Liquids that Are Exempt

Not all liquids are subject to these restrictions. Medications, for instance, in both liquid and solid form, are exempt. However, they are subject to extra scrutiny and might require additional time.

Certain products like snacks for infants or children, and frozen gel packs for cooling medical supplies, are also excluded. Ensure you keep these in a sealed, plastic bag, and be prepared for additional inspection.

What About Duty-Free Items?

When purchasing items in duty-free shops after security, liquids over 3.4 ounces or 100 milliliters can be packed in a sealed, security bag provided at the point of sale. These bags are considered secure until tampered with, and you should keep them with you throughout your journey.

Upon arrival at your destination, provided you can produce evidence of purchase, the liquids can then be placed in your checked luggage. Always check your airline's policy, as some may require liquids to be transferred to smaller containers or repacked upon arrival.

Tips for Packing Liquids

When packing liquids, it's best to use small, reusable, and squeezable containers. Consider decanting your favorites before the trip, and be mindful of your fragile items by wrapping them in clothing.
