Same call sign on two American Airlines flights prompts ATC alert near Phoenix

Just after midnight on 14 August 2026, air traffic control near Phoenix noticed a call sign conflict between two American Airlines flights, both numbered 2482, according to Flightradar24. One aircraft was descending through 11,000 feet on approach to Phoenix. The other was climbing through 9,000 feet after departing the airport.

Controllers and pilots realized the identical call sign was in use for both flights on the same frequency, raising the risk of confused instructions. Controllers responded by keeping the two aircraft at safe altitude separation and adjusting how they referred to each one, calling one "American 2482 on approach" and the other "American 2482 on departure" to tell them apart.

The two aircraft crossed paths without further incident, the report said, and both went on to land safely at their respective destinations.

The episode has been cited as another example of call sign confusion, a recurring concern in aviation safety. For years, industry discussion has focused on reducing the risk that similar or duplicated call signs cause miscommunication between pilots and controllers. Alphanumeric call signs and other mitigation measures have been proposed as solutions. US carriers, however, have not broadly adopted such changes, according to the report.

No injuries or damage were reported in connection with the event.
