Why is there a liquid limit on airplanes?

The ban was put in place after British authorities thwarted a plan to blow up a U.S.-bound plane with liquid explosives. There is now technology to send that ban down the drain.

Where does the 3.4 oz rule come from?

A terrorist plot named the 2006 Transatlantic Liquid Bomb Plot is why we have the 3.4-ounce limit in place for bringing liquids on airplanes.

Will TSA notice 4 oz?

6 Answers. For the most part, the 3.4oz rule isn't strictly enforced, in the sense that they don't normally physically check ever single container you have to make sure that it's less than 3.4oz. If it's significantly larger than 3.4oz they will normally be able to see that on the X-ray, and will physically inspect it.

Why is the TSA limit 3 oz?

According to the TSA, the limit is such that it would be impossible to use liquid/plastic explosives to take the plane down, while still allowing us to have our minimal amount of soap and shampoo for these 2-day business trips without having to check in any luggage.

When did the 3 oz rule start?

Sep. 2006. A month after the implementation of the original liquids ban, TSA amends its rules governing liquids in passenger carry-on baggage and allows airline passengers to carry liquids, gels and aerosols in containers of only 3.4 ounces or less in a single, clear, resealable 1-quart plastic bag.
