Overview
- A veteran Phoenix air traffic controller recognized two different American Airlines aircraft using the same callsign and separated them on the radio so both flights stayed safe.
- The inbound Chicago–Phoenix flight was delayed and a different plane operated the Phoenix–Chicago departure under flight number AA2482, which put both aircraft on the same Phoenix frequency.
- Flight-tracking data and ATC audio show the jets converged within legal separation of roughly three miles horizontally and about 2,000 feet vertically while controllers re-issued altitude instructions.
- The FAA has opened a formal investigation and American Airlines says it is reviewing the event and its operational procedures for aircraft substitutions and callsign assignment.
- Aviation experts and reporters point to routine flight-number reuse and gaps in dispatch coordination as the likely root causes, raising questions about system limits that let a single flight number be active on two aircraft.
