We have a new security control in Terminal 5 at Arlanda, with modern technology that makes it possible to bring more liquid. The 100 millilitre regulations continue to apply in all other security controls (at Arlanda and all other Swedavia airports). Be attentive to what the rules are for the security control you're in line for. If you're unsure of which rules applies, you can find them on signs in the line to the security control.
