The numbers
A power outage at Denver International Airport (DIA) occurred around 9:20 a.m. on March 18, 2026, leading to significant disruptions in airport operations. The outage lasted approximately 90 minutes, with power restored at 11:04 a.m. By 11:30 a.m., the Federal Aviation Administration (FAA) lifted the ground stop that had been implemented due to the outage.
During the outage, 353 flights were delayed and 6 flights were cancelled, causing considerable inconvenience for travelers. The airport was experiencing a surge in passenger traffic due to the spring break season, with around 80,000 people passing through security daily. The outage also impacted train service between terminals, further complicating travel for those at the airport.
Passengers reported being stuck on planes as the jet bridge could not retract, preventing them from disembarking. One traveler, known as u/ColoradoDreamin4917, shared their frustration, stating, “We were about to pull back from the gate and then found out the power is out. We’re stuck now because of the jet bridge.” Another passenger, u/dayvancowb0y, echoed similar sentiments, saying, “Stuck on a plane at a B gate because they can’t retract the jet bridge so we can’t close the door and leave 🙃.” These accounts highlight the challenges faced by travelers during the outage.
The outage at DIA is particularly notable given the airport’s ongoing efforts to secure an additional power source. With rapid expansion and increased power demand, the need for a reliable power supply has become increasingly critical. Observers have pointed out that such incidents could prompt airport officials to expedite plans for infrastructure improvements.
As the situation unfolded, airport authorities worked diligently to restore normal operations. The swift response to the outage and the subsequent restoration of power were crucial in minimizing further disruptions. However, the impact of the outage on travel plans for many passengers was already significant.
Details remain unconfirmed regarding the exact cause of the power outage. Investigations are likely to follow to determine what led to the disruption and how similar incidents can be prevented in the future.
As travelers continue to navigate the busy spring break period, the airport’s management faces the challenge of ensuring that such outages do not recur. The incident serves as a reminder of the importance of robust infrastructure in handling the demands of a major international airport.
