Investigating DIA Security Wait Times – All You Need to Know

Whether you are a seasonal traveller or a first-time traveller, one of the most stressful parts of any trip is getting through airport security. At Denver International Airport (DIA), the nation’s third-busiest airport, knowing what to expect can save you a significant amount of time and stress.  

Let’s break down the current DIA security wait times trends, what’s changing in 2025, and how you can beat the crowds.

Average DIA Security Wait Times

DIA has three main security checkpoints:

• South Checkpoint-  Main Terminal (Level 5)
• North Checkpoint- Level 5, near baggage claim
• West Security Checkpoint-  (less crowded, often used for PreCheck and Clear members)

Average Wait Times

The wait times might vary by time of day, but here’s a rough breakdown:

Time of Day	Typical Wait Time
4 a.m. – 6 a.m	15–30 minutes
6 a.m. – 9 a.m	30–45 minutes
9 a.m. – 1 p.m	15–25 minutes
1 p.m. – 4 p.m	10–20 minutes
4 p.m. – 7 p.m	30–45 minutes
After 8 p.m	Usually under 15 minutes

Top Tips for Minimizing Wait Times 

Let’s go straight to the good stuff! How can one avoid wasting precious minutes standing in line? Here are a few strategies that will help you breeze through security at DIA:

Arrive Early- Not too early, though!

DIA recommends arriving at least 2 hours before your domestic flight and 3 hours before an international one at the airport. It gives enough time to check in, get through security, a grab a bite before you board. However, arriving too early might not help you much if you are hoping to avoid crowds, so don’t show up at 4 a.m. for a 9 a.m. flight. 

Take Advantage of a TSA Pre-check

TSA  Precheck is a game-changer if you travel often. With Precheck, you don’t have to remove shoes, belts, or laptops, and you can go through the dedicated, quicker lanes. This service can save you a lot of time, especially when travelling through a busy airport like Denver International Airport. 

Use the North and South Security checkpoints wisely

Denver has multiple TSA Checkpoints: North, South, and Bridge Security for Concourse A. Although all checkpoints are similar in terms of security procedures, sometimes one checkpoint will be busier than others, depending on the traffic flow. 

Skip the Long Lines with CLEAR

If you are running in a hurry, CLEAR is another option to speed up security. CLEAR uses biometric screening, like fingerprints and eye scans, to help you get through security faster. 

Peak Travel Times to Watch Out for

• Early Morning: Between 5–8 a.m., when many flights depart for business travelers or early vacationers.

• Late Afternoon: From 3–6 p.m., when returning travelers flood the airport.
  
• Holiday and Ski Season: Expect longer waits during the holidays and winter months, when many people head to the slopes or take family vacations.

What Happens if You are Running Late?

Don’t panic if you are running late or if the queue appears to be wrapping around the terminal.  For passengers in a hurry, DIA offers a last-minute security checkpoint, which is efficient at getting you through quickly, especially for local trips.  The most excellent strategy, though, is always to be proactive with timing.

Patience is essential.

Security queues at DIA are unavoidable, just like at any other airport, but you can optimize your trip and reduce DIA security wait times with a little preparation.  You may reduce stress and ensure a more seamless travel experience by arriving early, using TSA PreCheck or CLEAR, and monitoring real-time wait times.
