America's most dangerous airports have been exposed by federal officials, with dozens of high-risk runway 'hot spots' flagged across the country.

Data from the Federal Aviation Administration shows 291 locations within US airports where the risk of runway incursions, near-collisions and taxiing errors are significantly elevated.

These hot spots are marked on pilot charts as areas with a documented history of confusion or heightened collision risk – places where even experienced crews can make critical mistakes. 

The danger is far from theoretical. In a fatal runway collision at New York's LaGuardia Airport on Sunday, those risks became a deadly reality. 

The problem is especially acute in California, where the FAA's latest report identifies 34 airports with more than 80 runway hot spots. 

It warns that complex layouts at San Francisco, Los Angeles and San Diego's main airports increase the risk of pilot error, confusion and potential accidents. 

At Phoenix Sky Harbor in Arizona, crews have mistaken taxiways for departure runways.

Other major hubs flagged by officials include Seattle-Tacoma, Harry Reid International in Las Vegas, Salt Lake City International and Albuquerque International Sunport, where wrong-runway departures, misalignment risks and complex layouts have all been highlighted.

Northeast 

The Northeast faces significant risks. Newark Liberty and Reagan National are known for their disorienting taxi routes and aircraft inadvertently entering active runways, while JFK, LaGuardia, Philadelphia and Boston remain under scrutiny due to dense traffic and packed intersections. 

At LaGuardia, those risks have now proved deadly. The collision of an Air Canada Express regional jet with a Port Authority fire truck killed two pilots and injured dozens more on Sunday. It will only intensify scrutiny on the airport's tight layout, intersecting runways and high traffic. 

The accident follows other frightening near-misses in the region. At Newark Liberty, close calls in 2025 and 2026 included technical failures causing 90-second radar blackouts, in-air near-collisions and emergency runway incidents. 

Pilots operating at New York's busiest airports must navigate a maze of taxiways where a single wrong turn can place an aircraft directly in the path of another.

In May 2025, a passenger jet at LaGuardia was forced to abort takeoff when another aircraft was taxiing on the same runway, with the two planes coming within just 0.27 miles of each other.

Because hot spots remain marked on official airport diagrams until they are resolved, each one on the map represents an active safety concern rather than a historical issue. 

Randy Klatt, flight safety officer for The Foundation for Aviation Safety, told the Daily Mail: 'No airport is designed to be more unsafe, but they can't all be neatly laid out on 50 square miles.'

The FAA defines a hot spot as any area where the risk of collision or runway incursion is significantly elevated, often due to confusing layouts or limited visibility.

West Coast 

California accounts for a significant share of these high-risk hot spot zones. 

At Los Angeles International Airport, aircraft often exit one runway only to approach another within seconds, leaving little margin for error. 

The airport has recorded multiple near-misses in recent years, including a September 2024 incident in which an American Airlines jet aborted takeoff at high speed to avoid a cargo plane crossing the same runway.

San Francisco International faces similar risks due to its complex layout, which has been linked to one of the most alarming near-disasters in US aviation history, when a pilot nearly landed on a taxiway crowded with aircraft. 

Federal records show the airport has averaged about three runway incursions per 100,000 flights since 2010, with incidents peaking in 2023.

Across California, airports from Oakland to San Diego continue to report pilots missing turns, mistaking taxi routes, or inadvertently entering active runways, problems that extend to smaller facilities where tight spacing and unclear markings increase the risk of error. 

In 2022, three people were killed when two aircraft collided midair while approaching Watsonville Municipal Airport, highlighting the dangers even outside major hubs.

Similar concerns have emerged in the Pacific Northwest, where airports including Seattle-Tacoma and Portland have reported repeated cases of aircraft entering active runways without clearance, often due to misread instructions, poor visibility, or limited signage.

Southwest 

Arizona’s airports face a distinct set of risks tied to pilot confusion and crowded airspace. 

At Phoenix Sky Harbor International Airport, pilots have mistaken taxiways for runways and crossed into active flight paths, contributing to multiple close calls over the past decade.

In 2025, the FAA launched an investigation after two passenger jets carrying hundreds of travelers nearly collided near Phoenix, coming within just 425 feet of required separation.

Across neighboring states, layout and visibility remain major concerns. 

Albuquerque International Sunport in New Mexico has converging taxiways that create frequent confusion points.

Salt Lake City International Airport in Utah has reported aircraft entering active areas from ramps or misjudging short distances between runways, including a 2024 incident in which two aircraft passed within 530 feet of each other after a communication breakdown.

In Nevada, Las Vegas’s Harry Reid International Airport has been flagged for alignment risks, where pilots have mistakenly lined up on the wrong runway, an error that can lead to catastrophic consequences.

Midwest 

Colorado's high-altitude airports add another layer of complexity. 

At Denver International, one of the busiest airports in the country, pilots have crossed into protected runway areas without clearance, while nearby airports report confusion caused by vast, open pavement that makes it difficult to distinguish between taxiways and runways. 

The FAA data shows that congestion and tight runway spacing are among the biggest safety concerns at major airports across the Midwest.

Hubs including Chicago O’Hare, Minneapolis–St Paul, Kansas City International, Des Moines and St Louis Lambert have been flagged for complex taxiway intersections and rapid runway crossings that leave pilots with little margin for error.

Officials warned that many Midwest airports operate under heavy traffic pressure, where aircraft must move quickly through crowded layouts, increasing the risk of runway incursions and close calls during peak operations.

Klatt noted that while Denver's wide layout and parallel runways were designed for efficiency, older airports such as Chicago O'Hare face different challenges, including congested taxiways, limited space, and decades of runway expansions layered onto aging infrastructure.

'Most large US airports are surrounded by development and have little room to expand,' Klatt said. 'As traffic increases at older, crowded airports, the potential for safety issues naturally rises.'

South

In the Southeast, Atlanta's Hartsfield-Jackson Atlanta International Airport (ATL), one of the busiest in the world, faces constant pressure from volume and layout, with pilots navigating tightly spaced runways and taxiways that can quickly lead to confusion. 

In August 2025, a Delta Air Lines plane clipped an empty parked aircraft during pushback at ATL, marking a notable incident involving aircraft contact

Florida's major airports have also experienced repeated incidents involving wrong-runway alignments and unauthorized crossings.

The airport suffered another incident a year prior when two Delta Airline planes collided in the morning.

The crash occurred after Tokyo-bound flight DL295 clipped the back of flight DL5526 to Louisiana as it was taxiing for takeoff.

The regional jet, an Endeavor Air CRJ-900, was left with a severed tail while the Airbus 350 sustained damage to its wing.

Remote airports 

Alaska presents some of the most challenging conditions in the country. 

At Anchorage, low visibility and complex layouts have led to aircraft crossing runways unintentionally, while other airports report confusion compounded by weather and even unauthorized vehicles entering movement areas.

Hawaii adds its own unique risks, as at Honolulu Airport (HNL), pilots have missed turns and entered active runways, while at other airports, aircraft and ground vehicles share tightly constrained spaces. 

In early 2023, officials investigated at least three separate runway close-calls in under a month at HNL, including a United Airlines flight that crossed a runway while a Cessna cargo plane was landing. 

Taken together, the FAA's findings reveal a nationwide web of risk stretching far beyond a handful of problem airports. 

Because these hot spots remain active until they are corrected, federal officials are sending a clear warning: these are not isolated incidents from the past, but ongoing dangers pilots are still navigating today.
