What is the "3-1-1" rule?

Nico Melendez (TSA Regional Spokesperson) gives expert video advice on: Why do I have to set aside electronic equipment like my laptop and PDA?; What is the best way to travel with camera and film equipment?; What can I do if I feel a TSA employee has treated me inappropriately? and more...

3-1-1 is a campaign that we initiated in September 2006 to help passengers understand the allowances made for traveling with liquid. The 3-1-1 rule allows three ounce containers of liquid, one zip top baggie, one quart size source. Three ounces, one quart, one baggie. You can have as many three ounce containers in that baggie as you can fit comfortably. However, 3-1-1 allows one baggie per person, and it must be one quart size.
