Update from DEN: Monday morning passengers at DEN experienced significant lines across all security screening checkpoints resulting in lengthy wait times to get through security.

We’ve been in contact with local and national TSA leadership to understand what resources and staffing they had in place this morning, how the lanes were being operated, what advance planning took place, traffic projections, equipment issues and more. At the same time, we are reviewing our own operation regarding how we manage the lines outside the checkpoint. TSA and DEN continue to work together in partnership to address the challenges we are having so that we can best accommodate the numbers of passengers traveling through DEN, particularly at peak times. We are encouraged by the performance of the equipment in the new West Security Checkpoint and the vast majority of times, wait times are below 10 minutes. However, we know there was a problem during peak time on the morning of Feb. 26 and we are going to do everything we can possibly do, working with TSA and our airlines, to fix this situation. Our passengers deserve an amazing, efficient and positive travel experience and we are committed to providing just that.

Denver International Airport Trains Will Undergo Scheduled Overnight Shutdowns in February


Assessment of the system’s power distribution system will help the airport prepare for the future and the arrival of new train cars expected to go into service this summer

DENVER – Feb. 8, 2024 – Denver International Airport’s (DEN) trains to the concourses will be shut down overnight for six days in February for scheduled testing of the train’s electrical power system. The scheduled testing will help DEN airport operations evaluate the AGTS (Automated Guideway Transit System) power distribution system and the critical infrastructure systems that are necessary to support the 26 new trains arriving at DEN this year.

“This effort will help ensure the resiliency of our automated people mover, the train, by evaluating the condition of aging electrical infrastructure while also providing critical information required for current operations and future expansion as we work toward 100 million annual passengers,” said DEN CEO Phil Washington.

The closures will take place from 9:15 p.m. to 3 a.m. on Feb. 13 and 14, 20 and 21 and 27 and 28, and will impact passengers getting to and from the B and C Concourses. Employees and passengers will need to use Bridge Security, which will be the 24-hour checkpoint starting at 8 p.m. Once past security, those who need to reach the B and C concourses will be guided to a bus that will take them to the concourses via signage and/or airport personnel.

“DEN Operations is working hard to minimize the impact to passengers and employees. That is why we will have buses operating between the Terminal and concourses, we’re working with airlines to communicate with traveling passengers in advance of their flights, we’re maximizing gate space on Concourse A, and it’s why the tests will be conducted overnight,” said Sarah Marquez, Senior Vice President of Airport Operations.

It is recommended that passengers who need to get to the B and C Concourses during these hours should arrive to security at least 30 minutes earlier than they would have otherwise to ensure they have enough time to move through the airport.

Additional communication during these closures will be on and on DEN’s social media channels. Contingency dates will be the Saturdays of the same week.
