Travellers are being reminded that stainless steel water bottles must be completely empty when passing through UK airport security. The rule, which applies to all reusable metal containers, can cause delays at checkpoints if not followed.
Security scanners cannot see through stainless steel, meaning bottles must be empty to avoid additional screening. Passengers are advised to empty their bottles before joining the security queue to speed up the process.
The reminder comes as many travellers are unaware of the requirement, leading to hold-ups. Airport staff may ask passengers to empty bottles or dispose of liquids, potentially causing frustration.
For those who wish to carry water, empty bottles can be refilled at water fountains after security. This rule is part of standard UK airport security measures for all metal containers.
