An air traffic controller at Phoenix Sky Harbor International Airport intervened to prevent a potential disaster on August 14, 2026, after two American Airlines flights were mistakenly assigned identical flight numbers in the same airspace, according to reports from The Associated Press and FOX 10 Phoenix.
How Duplicate Call Signs Sparked a Mid-Air Close Call Over Phoenix
The close call occurred just after midnight on August 14. Flight 2482 involves a routine round-trip rotation, but severe weather out of Chicago disrupted the schedule, according to Flightradar24 data cited by FOX 10 Phoenix. To keep the aircraft rotation on track, American Airlines deployed a substitute plane out of Phoenix for the outbound leg. This operational fix created a dangerous overlap: two distinct aircraft operating under the exact same call sign simultaneously.
Live air traffic control audio captured the tense moments when the controller realized both planes occupied the same frequency and airspace. The inbound flight from Chicago was descending through 11,000 feet toward Sky Harbor, while the outbound flight was climbing through 9,000 feet.
Quick Controller Intervention Preserved Required Separation
Recognizing the immediate hazard, the Phoenix air traffic controller issued rapid instructions to split the aircraft onto distinct vertical profiles. The controller maneuvered the arriving flight to hold at 11,000 feet while keeping the departing flight capped at 9,000 feet until the conflict cleared, eventually authorizing the outbound plane to climb to 21,000 feet.
To manage communications safely while the planes shared a frequency, the controller began explicitly addressing the aircraft as “American 2482 on approach” and “American 2482 on departure.” Once vertical separation was firmly established, the controller expressed visible relief over the radio broadcast, stating, “I’m glad it all worked out there.”
Passenger Manifests and Airline Response
A total of 295 passengers were onboard the two aircraft combined, according to figures released by American Airlines. The inbound flight carried 122 passengers, while the outbound leg to Chicago transported 173 travelers.

In a statement provided to The Associated Press, American Airlines defended the professionalism of its flight crews. “The diligence and professionalism of air traffic controllers and our pilots ensured required separation was always maintained and the issue was identified and addressed. Both flights continued safely and without incident,” the airline said.
What Comes Next for FAA Oversight
The Federal Aviation Administration launched a formal investigation into the incident to determine how dispatch systems allowed duplicate call signs to enter active control sectors simultaneously.
