Liquids that do not comply with TSA’s 3-1-1 rule

Understanding these prohibited liquids is essential for a smooth travel experience with Delta Airlines.

Alcoholic Beverages Over 70% Alcohol Content: Delta Airlines prohibits alcoholic beverages that have an alcohol volume exceeding 70%. These liquids pose a significant safety risk due to flammability and intoxication. According to the Transportation Security Administration (TSA), consumption of highly concentrated alcohol can impair judgment, making it a potential hazard in an enclosed space like an airplane.

Hazardous Materials: Hazardous materials include a wide array of items such as corrosive liquids, toxic substances, and any form of explosive materials. Delta adheres strictly to federal guidelines on hazardous materials to prevent potential threats to passenger safety. For example, batteries containing hydrofluoric acid fall into this category.
Items Packaged in Containers That Exceed 3.4 Ounces (100 Milliliters): Delta enforces the TSA’s 3-1-1 rule. Under this rule, liquids, gels, and aerosols must be in containers of 3.4 ounces or less, and all must fit into a single quart-sized bag. This measure is intended to limit the amount of liquid substance that could be harmful in case of an incident onboard.
Liquids That Do Not Comply With TSA’s 3-1-1 Rule: Any liquids or gels that exceed the established limits or do not fit the specified guidelines set by the TSA are prohibited. This rule applies universally to all airlines, including Delta, to safeguard passengers and crew from risks associated with carrying excess liquids.

Passengers should familiarize themselves with these restrictions to ensure compliance and a hassle-free travel experience with Delta Airlines.
