Weather Impact and Flight Status
Severe thunderstorms swept across Colorado each day of the Memorial Day weekend, leading to a domino effect of flight delays at Denver International Airport. These storms were part of a larger weather system, with the risk of thunderstorms forecasted for every day of the holiday period. The impact was immediate and widespread:
- Hundreds of flights were delayed, affecting thousands of travelers.
- The delays began as early as Thursday, May 22, and continued through Tuesday, May 27.
- The airport had already been dealing with recent communication outages, where up to 20 pilots could not speak with air traffic controllers for several minutes due to radio transmitter problems.
Visual Description: Imagine the airport’s departure and arrival boards filled with red “DELAYED” notices, and long lines of passengers waiting at check-in counters and security checkpoints. Outside, dark clouds and heavy rain made it difficult for planes to take off or land safely.
Passenger Volume and Airport Preparations
Denver International Airport had prepared for a record-breaking Memorial Day weekend:
- 443,000 passengers were expected to pass through security checkpoints between May 22 and May 27.
- This number matched the high volume seen in 2024 and was a significant jump from 2023, which saw over 400,000 travelers—a 9.4% increase from 2022.
- The busiest days were projected to be May 22 and 23, with more than 80,000 passengers moving through security each day.
Visual Description: Security lines snaked through the terminal, with travelers carrying bags and families trying to keep children entertained. Airport staff directed people to different checkpoints to manage the crowds.
Airport Security and Facilities
To handle the surge in travelers, Denver International Airport made several operational changes:

- A-Bridge Security Checkpoint: Standard screening, open 4:30 a.m. to 5:45 p.m.
- West Security Checkpoint (Level 6, Northwest corner): Main checkpoint for TSA PreCheck, open 4 a.m. to 7:30 p.m.
Parking Adjustments:
- The Pikes Peak lot had limited space due to construction, so travelers were sent to the Landside parking lot at 6975 Valley Head Street for overflow.
- The Pikes Peak and Longs Peak shuttle lots closed temporarily on Friday, May 24, from 3 a.m. to 5 p.m.
- Shuttle buses continued to run between all parking lots and the terminal.

- The East Security Checkpoint reached 50% completion in August 2024.
- 24 airline check-in and bag drop counters were temporarily moved from Level 6 to Level 5 in the Jeppesen Terminal’s east and west sides. This change began April 9 and will last until June 30, 2025, with some counters staying on Level 5 through mid-2027.
