Empty Bottles vs Liquid-Filled
Allowed
Empty bottles are allowed through security. Filled bottles over 100ml are confiscated unless exempt.
Quick answer
Security focuses on liquid volume, not container size. Showing a bone-dry bottle proves compliance instantly.
Vacuum flasks, metal tumblers, and collapsible silicone bottles are all acceptable empty. Residue can trigger swab tests, so rinse thoroughly before travel.
Once you refill past security, remember to empty the bottle again before any additional checkpoints on multi-leg itineraries.
Before security
- âPour out all liquids, including melted ice, right before joining the queue.
- âSeparate bottle lids/caps and keep them in the tray if officers request it.
- âWipe condensation to avoid confusing scanners.
After security
- âUse drinking fountains or water stations to refillâIndian airports are adding them near each gate.
- âEmpty the bottle again before transiting through another security checkpoint.
- âLabel your bottle with initials so it doesnât get mixed up in crowded trays.
Container quick reference
| Container | Empty allowed? | Notes |
|---|---|---|
| Reusable plastic bottle | â | Keep lid off if asked |
| Vacuum flask | â | May be swabbed |
| Thermal mug with foam sleeve | â | Remove sleeve for inspection |
Do this
- â Use wide-mouth bottles so officers can easily inspect the interior.
- â Carry a small carabiner to hang the bottle from your bag after refilling.
- â If you rely on electrolyte mixes, pack single-serve sachets and add them only after clearing security.
Avoid this
- â ď¸ Donât argue if officers insist on a swab testâmetal walls often trigger alarms.
- â ď¸ Avoid hiding liquids inside insulated sleeves; scanners detect density differences.
- â ď¸ Donât fill the bottle while still in the queue; wait until you have fully cleared screening.
FAQ

Yes, but wrap it securely. Sharp glass edges may still trigger manual inspection.
Q. Are collapsible hydration bladders allowed?
Yes when empty. Hang them flat in the tray so officers can see both sides.
Q. What about soda cans I plan to recycle?
Empty cans can go through, but crushed metal sometimes alarms scanners. Expect secondary screening.
Tips before you fly
