Starting today, September 1st, the European Commission’s new regulation re-imposes the 100ml limit on containers for liquids transported on airplanes. This rule, which is being implemented across all airports with state-of-the-art scanners, is a temporary measure according to the Commission. This means that passengers will need to ensure that their liquids are in containers that comply with the 100ml limit and that they are placed in a transparent, resealable bag for security checks.
