More than 200 flights were delayed or canceled at Phoenix Sky Harbor International Airport on Thursday, June 4, after the FAA issued a ground delay program tied to air traffic controller staffing shortages, FOX 10 reported.
The disruption was widespread. The Arizona Republic put the total closer to 300 delayed flights, while KTAR reported the FAA capped arrivals at 36 per hour Thursday evening, with average delays reaching 74 minutes. 12News confirmed the airport itself acknowledged the delays, cancellations, and diversions.
Operations returned to normal by Friday morning, June 5, FOX 10 said.
The staffing shortage affecting Phoenix mirrors a broader strain on FAA air traffic control capacity that has drawn scrutiny from Congress and aviation regulators in recent months. Sky Harbor, which serves as the primary commercial gateway for the Phoenix metro, handles roughly 1,200 daily flights during peak summer travel season.
No timeline has been released for when the FAA expects to resolve the underlying controller staffing gap at the Phoenix facility.
