When did TSA start banning liquids?

2006. Terrorists plot to detonate liquid explosives carried onboard at least 10 airliners traveling from the UK to United States and Canada. British Police foil the plot. In response, TSA bans all liquids, gels and aerosols from passenger carry-on luggage.



The TSA first implemented the ban on liquids, gels, and aerosols in carry-on luggage on August 10, 2006. This sudden policy change was a direct response to a foiled terrorist plot in the United Kingdom known as Operation Overt, where extremists planned to blow up multiple transatlantic flights using liquid explosives disguised as soft drinks. Initially, the ban was absolute, but after a few weeks of intense research into liquid detection, the rules were relaxed in September 2006 to allow small quantities. This led to the creation of the now-ubiquitous "3-1-1 Rule": 3.4-ounce (100ml) containers, all fitting in 1 quart-sized clear bag, with 1 bag per passenger. Although 2026 sees many airports upgrading to advanced CT scanners that allow for larger liquids to stay in bags, the 2006 security mandate fundamentally changed global travel culture, turning the "clear plastic bag" into a permanent requirement for millions of travelers worldwide for the last two decades.
