An air traffic controller in Phoenix averted a potential mid-air collision late Thursday night after two American Airlines jets—one arriving from Chicago and another departing for Chicago—were assigned the same flight number, American 2482, creating confusion in shared airspace.
The controller, who has 25 years of experience, identified the duplicate call signs and issued clear instructions to distinguish between the two aircraft, ensuring they maintained safe separation as their flight paths converged. Both planes continued safely without incident, according to the Federal Aviation Administration (FAA) and American Airlines.
How the incident unfolded
The near-miss occurred around 12:00 a.m. local time on August 14 near Phoenix Sky Harbor International Airport. The arriving flight, American 2482, was descending from Chicago, while a departing flight with the same call sign was simultaneously taking off for Chicago. The controller recognized the risk of confusion and began referring to the planes as “American 2482 on the arrival” and “American 2482 on the departure” to clarify instructions.
The controller kept the arriving aircraft above the departing jet as their paths crossed and instructed the departing plane to limit its climb, preserving a vertical gap. Audio of the incident, posted by ATC.com, captures the controller saying: “I’ve been working air traffic for 25 years. I’ve never seen two aircraft pretty much merge with the same call sign. That’s pretty incredible.” The arriving pilot later commended the controller’s work, calling it “nice work.”
Why the same flight number was used
American Airlines attributed the mix-up to a delayed inbound flight from Chicago. The original plan called for the arriving aircraft to land in Phoenix, disembark passengers, and depart again as American 2482 to Chicago. However, due to the delay, a different aircraft was substituted to transport waiting passengers, resulting in two planes operating under the same call sign simultaneously.
The airline stated it is reviewing the details of the incident, while the FAA confirmed it is investigating the circumstances surrounding the duplicate flight numbers.
Safety protocols and responses
The FAA emphasized that required separation was maintained throughout the incident, and both flights continued safely. An American Airlines spokesperson said in a statement: “The diligence and professionalism of air traffic controllers and our pilots ensured required separation was always maintained, and the issue was identified and addressed.”
Aviation safety expert Steve Arroyo suggested the incident likely resulted from an oversight in the airline’s dispatch operations, where flight plans are typically reviewed and approved by both dispatchers and pilots. Arroyo noted that such an overlap would normally be caught during standard procedures.
Regulatory and industry implications
The incident comes amid heightened public scrutiny of aviation safety, following a series of high-profile air travel incidents and near misses. While the FAA and American Airlines have not indicated any immediate policy changes, the event raises questions about flight number assignment protocols and real-time monitoring of overlapping flight paths.
The FAA has not yet released a timeline for its investigation or any preliminary findings. American Airlines has not provided additional details about its internal review process.
