Airport Security: Wait Times & TSA Information

Security wait times at DEN can vary based on the time of day and passenger volume. To check real-time security wait times before you arrive, visit our Security Wait Times page. We recommend arriving at least two hours before your flight to allow ample time for security screening. Additionally, DEN offers expedited screening options like TSA PreCheck and CLEAR to help streamline your experience.​

Certain items are prohibited through TSA security, including:

• Weapons and sharp objects (e.g., firearms, knives)
• Flammable items (e.g., aerosols, butane)
• Explosives and fireworks
• Large liquids or gels (over 3.4 oz)
• Certain batteries (e.g., lithium metal)

For a complete list of prohibited items, visit the TSA What Can I Bring? page.

To follow TSA’s 3-1-1 rule for liquids, aerosols, gels, creams, and pastes:

• Containers must be 3.4 oz (100 ml) or less.
• Place them in a single, clear, resealable quart-sized bag.
• Only one bag per passenger.

These items should be placed in your carry-on and removed for separate screening. Larger quantities should be packed in checked baggage.

Exceptions: Medications, baby formula, breast milk, and baby food are allowed in larger quantities but must be declared at the checkpoint.
