A potentially hazardous situation occurred near Phoenix involving two American Airlines flights. Normally, these flights operate at different times, but a delay caused them to be in the same airspace simultaneously. Flight-tracking data indicates the planes were in close proximity, with about 3 miles of horizontal separation and a vertical separation of 2,000 feet.

Further information about this incident is available from the source, including details about the flights and the actions taken by air traffic controllers to manage the situation.
