Empty Bottles vs Liquid-Filled

Yes — Allowed

Empty bottles are allowed through security. Filled bottles over 100ml are confiscated unless exempt.

Empty bottles—plastic, metal, or glass—sail through security. As soon as they contain more than 100ml of liquid, they fall under the LAG rule unless covered by baby food or medical exemptions. Keep lids off if officers request a visual check.

What to do

Do

  • Use wide-mouth bottles so officers can easily inspect the interior.
  • Carry a small carabiner to hang the bottle from your bag after refilling.
  • If you rely on electrolyte mixes, pack single-serve sachets and add them only after clearing security.

🚫 Don't

  • Don’t argue if officers insist on a swab test—metal walls often trigger alarms.
  • Avoid hiding liquids inside insulated sleeves; scanners detect density differences.
  • Don’t fill the bottle while still in the queue; wait until you have fully cleared screening.

On multi-leg itineraries, remember to empty the bottle again before each additional security checkpoint — it doesn't stay cleared once refilled past the first one.
