Step by step
Check container sizes
Every liquid container must be 3.4 oz (100ml) or smaller. The size printed on the container matters, not how much liquid is inside. A half-empty 6 oz bottle will be confiscated.
Get the right bag
Use a clear, quart-sized (roughly 8x8 inch) zip-top plastic bag. One bag per passenger. Airport security provides these bags, but bring your own to save time.
Pack liquids together
Put all liquid containers in the clear bag. This includes toiletries, medications, contact solution, makeup, and any gels or creams. The bag should zip closed completely.
Keep bag accessible
Pack your liquids bag in an easily reachable spot in your carry-on. You'll need to remove it at security screening in most countries.
Know the exceptions
Prescription medications, baby formula, and breast milk are exempt but may require additional screening. Declare these items to security officers.
Questions people ask
Can I bring full-size containers in checked luggage?
Yes, checked luggage has no liquid restrictions. Pack liquids in sealed bags to prevent leaks from damaging other items.
What happens if my liquid bag doesn't fit in the scanner bin?
Security will ask you to remove items until the bag fits. Overpacked bags slow down screening and may result in items being discarded.
Are solid toiletries really exempt?
Yes, solid deodorant, bar soap, and solid shampoo bars don't count as liquids. But anything that could melt (like solid perfume) may be treated as liquid.
Can I bring multiple quart bags?
No, one quart bag per passenger is the limit. If you need more liquid space, use checked luggage or buy items after security.
Budget
Clear quart bags cost $0.50-1.00 each. Travel-size containers range from $1-3 per item. Expect to spend $10-15 total replacing full-size toiletries with travel versions.
