How to Navigate Security Checkpoints at DIA?

Denver International Airport is a bustling hub with an extensive layout, navigating the security checkpoints at DIA is no piece of cake. With two fully functional checkpoints: the West Security Checkpoint and the South Security Checkpoint, this navigation guide will work as an essential tool in your journey.

Here’s a detailed step-by-step guide to navigating these checkpoints. Let’s begin!

1. West Security Checkpoint (Level 6)

The West Security Checkpoint is DIA’s newest and most advanced checkpoint, featuring 17 lanes equipped with cutting-edge technology that enhances both efficiency and passenger experience. 

How to Navigate the West Security Checkpoint:

Locate the Entrance:

• This checkpoint is located on the northwest end of Level 6, near United Airlines’ ticketing and check-in counters.
• If you’re being dropped off, use Doors 606–600 on Level 6. 

Note: TSA PreCheck access is closest to Doors 602 and 600.

Choose the Correct Entrance:

• West Security 1: This entrance is just for standard screening passengers.
• West Security 2: This is for the ones having appointment-based reservations (DEN Reserve), Premium Access, military personnel, or passengers with accessibility needs.
• West Security 3: TSA PreCheck travelers and CLEAR customers should access this entrance to receive special benefits.

Prepare Your Documents:

Have your boarding pass (digital or physical) and a valid ID ready. 

Note: Starting May 7, 2025, a REAL ID-compliant document will be required by travelers to board domestic flights.

Screening Process:

Place your items in bins provided at the checkpoint. Since advanced scanners have been installed at these new security checkpoints, you can leave liquids (under 3.4 oz) and electronics in your bag.

Post-Screening:

Retrieve your items after screening. Bins are automatically returned for reuse. Use escalators or elevators to access the train platform on Level 4, which connects to Concourses A, B, and C.

Key Features of the West Checkpoint:

• Advanced technology allows multiple passengers to place items in bins simultaneously.
• Automatic diversion of flagged bags for secondary inspection ensures smoother flow for others.
• Larger bins accommodate more items and larger carry-ons.

2. South Security Checkpoint (Level 5)

The South Security Checkpoint remains operational but lacks some of the advanced features of the West Checkpoint. It primarily serves standard screening passengers.

How to Navigate the South Security Checkpoint:

Locate the Entrance:

• The South Security Checkpoint is on Level 5 of the Jeppesen Terminal near baggage claim areas.

• Follow signs for “South Security” if entering from ground transportation or parking areas. Here’s a detailed Denver Airport Parking Map guide to navigate with ease. 

Prepare Your Documents:

Have your boarding pass and ID ready for inspection. This step usually takes longer compared to other steps since it requires thorough verification while navigating through the security checkpoints at DIA. 

Pro Tip: Enroll in TSA PreCheck for faster clearance. 

Screening Process:

• Place all items in bins as directed by TSA agents.
• Remove liquids (under 3.4 oz) and electronics unless otherwise instructed.
• CLEAR customers can use expedited identity verification but will proceed through standard screening lanes unless they also have TSA PreCheck.

Post-Screening:

After clearing security, take escalators or elevators down to access the train platform for transport to Concourses A, B, or C.

Key Features of the South Checkpoint:

• It operates from 3 a.m. to 1 a.m., making it ideal for late-night travelers.
• Wait times can vary significantly depending on passenger volume; check real-time updates via DIA’s website or app.

Tips for Navigating Security Checkpoints at DIA

Arrive Early:

The key to smooth onboarding and navigating with ease is, to give yourself enough time to avoid last-minute chaos. Try to arrive at least two hours before domestic flights and three hours before international flights—especially during peak travel times like holidays or early mornings.

Use Real-Time Wait Times:

Monitor current wait times via DIA’s website or app to choose the fastest checkpoint.

Enroll in Expedited Services:

In order to speed up the process, programs like TSA PreCheck, CLEAR, or DEN Reserve can significantly reduce wait times:

• TSA PreCheck: Allows you to keep shoes, belts, and laptops in your bag.
• CLEAR: Offers biometric verification for faster identity checks.
• DEN Reserve: Lets you book a time slot for expedited access at West Security 2.

Pack Smartly:

Follow TSA guidelines for liquids (3-1-1 rule), avoid banned items, and organize your carry-on bag for easy inspection, if needed.

Travel Off-Peak:

Midday weekdays typically have shorter lines compared to early mornings or holidays.

Choose Parking Lot Wisely: 

What if you do everything listed above and still get stuck with parking issues such as mismanagement at the parking lot, fare-related issues, security issues, and others?
