Multiple outlets report on criticism of the common airport rule limiting passengers to liquids in containers of up to 100ml. The reporting describes how travelers routinely face restrictions that require placing liquids in bins and discarding items that exceed the limit, which can include toiletries and drinks purchased before boarding. According to the account, a Harvard-linked expert argues that the policy is largely ineffective and does not meaningfully improve security, characterizing it as “security theatre.”
The coverage presents the rule as a widely recognized travel ritual rather than a clearly targeted measure. It also notes the practical impact on travelers, including the need to check and repack liquids to comply and the potential for last-minute losses at security checkpoints. Overall, the sources focus on questioning the logic and effectiveness of the 100ml limit, while describing how the rule is applied in everyday airport screening. The reporting does not indicate any change to current regulations, focusing instead on expert skepticism about the rationale behind them.
