Denver’s airport has faced significant challenges over the past 30 years, beginning even before its opening. Its baggage handling system has been the subject of numerous case studies highlighting failures. Currently, the systems designed to manage passenger flow are under scrutiny.
For over a decade, TSA checkpoints at Denver International Airport have struggled with issues related to layout and staffing. It remains one of the few airports in the country where passengers with both PreCheck and CLEAR frequently experience delays comparable to those faced by average travelers. While Atlanta's airport also faces similar issues, Denver's situation is reportedly worse.
The difficulties do not end after clearing security. Passengers must still reach their concourses, and walking options are limited. The airport relies heavily on a train system that often malfunctions.
