Map: Sky Harbor Airport
PHOENIX -- A relatively brief power outage caused some minor complications at the Southwest Airlines concourses at Terminal 4 Thursday morning.
While partial backup power kicked in and main power was quickly restored, the outage triggered some flight delays and closed the security checkpoint at Concourse D for a time.
Although everything was back up and running by 11:15 a.m., airport officials were still encouraging passengers to check flight status with their airline before coming to Sky Harbor.
About a dozen flights with 10 a.m. or 11 a.m. departure times were delayed. The longest of those delays was less than 30 minutes.
3TV's Kristine Harrington said she smelled smoke when she arrived at Concourse D. She said the security checkpoint leading to the D gates was closed and that passengers were being rerouted to the A and C concourses.
That checkpoint has since reopened and is operating normally.
Inbound passengers were affected, as well. Passengers on arriving flights used old-fashioned stairs to disembark as opposed to the usual jetways.
It's not clear what triggered the power outage, but there was a report of a small fire in an electrical box.
Concourse D is the smallest of the four concourses that make up Terminal 4. It houses just eight gates, all of which are run by Southwest Airlines.
