Airlines restrict liquids on planes primarily due to security concerns. The policy originated after a 2006 terrorist plot was uncovered, where attackers planned to use liquid explosives disguised as soft drinks to blow up planes. To mitigate such risks, the Transportation Security Administration (TSA) implemented the 3-1-1 rule, which allows passengers to carry liquids in containers of 3.4 ounces or less, inside a single, clear, quart-sized bag. This measure is crucial in preventing the introduction of explosives and ensuring the safety of all passengers onboard.
