American 737-800s involved in Phoenix conflict had identical callsigns

A controller at Phoenix Air Route Traffic Control Center (ARTCC) intervened to separate conflicting aircraft operations on the Chicago O’Hare route. The incident involved an extraordinary situation where two American Airlines Boeing 737-800s, both operating flight number AA2482, were using identical call signs. Radio communications revealed that the controller successfully resolved the converging outbound and inbound services. This necessitated a critical action to prevent potential safety hazards during air traffic control procedures.
