**How Does Airport Security Check Liquids?**

Airport security has strict regulations when it comes to liquids. Passengers are only allowed to carry liquids in containers of 3.4 ounces (100 milliliters) or less, and these containers must be placed in a single, clear, quart-sized plastic bag. This bag must be removed from your carry-on luggage and placed in a bin for screening. Any containers larger than 3.4 ounces will not be allowed through the security checkpoint, unless they are medically necessary, in which case additional screening may be required.

**Frequently Asked Questions About Airport Security and Liquid Restrictions**
