DENVER- Chicago-based carrier, United Airlines (UA), performed a go-around at Denver International Airport (DEN) after an Aeromexico plane was slow to exit the active runway on April 22, 2025.
The Federal Aviation Administration (FAA) reported the incident and said the go-around is a safe maneuver.

United Go-Around at Denver
According to FlightRadar24 data, United Airlines flight UA2151 took off from New York, Newark Liberty International Airport (EWR) at 14:48 UTC.
After being airborne for around four hours, the flight crew was prepared to land at Denver and was on final approach.
However, ATC ordered the crew to perform a go-around because the Boeing 737 MAX 9 belonging to Aeromexico (AM) performing flight AM658 had not yet left the active runway.
Here’s the ATC conversation captured by LiveATC.net and shared by CBS News on Instagram:

The FAA, in its report, stated:
An air traffic controller instructed United Airlines Flight 2151 to perform a go-around at Denver International Airport because an aircraft was slow to exit the runway. The event occurred around 12:40 p.m. local time on Tuesday, April 22. The required separation was maintained.

What is Go-Around?
Aviation safety protocols include a vital procedure called the go-around, which occurs when an aircraft aborts its landing approach and rejoins the landing queue. This maneuver activates when landing conditions fail to meet safety requirements and can be initiated by either pilots or air traffic controllers.
Multiple situations trigger go-arounds in aviation operations. Pilots execute this procedure when encountering unstabilized final approaches where aircraft speed, altitude, or positioning parameters fall outside acceptable ranges.
Air traffic controllers order go-arounds when the separation between aircraft becomes insufficient or when communication problems develop between ground control and flight crews. Additionally, airport vehicles inadvertently entering runways sometimes necessitate last-minute flight path adjustments.
The aviation industry considers go-arounds essential safety tools rather than operational failures or problems. A typical go-around creates only a 10-15 minute delay while prioritizing passenger and aircraft safety above scheduling considerations.
This procedure represents one of many safeguards embedded within aviation protocols to maintain the industry’s exceptional safety record.

Similar Incident
An American Airlines (AA) flight from Los Angeles International Airport (LAX) to Charlotte Douglas International Airport (CLT) executed an emergency go-around procedure Friday afternoon (March 28, 2025) when air traffic controllers identified a runway conflict.
Flight AA 938 aborted its landing at approximately 1:19 PM when controllers instructed the crew to pull up due to a small aircraft still occupying the designated runway.
The Airbus A321 immediately climbed steeply away from its approach path and entered a holding pattern for approximately 20 minutes before receiving clearance to land safely. This standard safety maneuver prevented a potential collision on the runway.
CNN contributor Lulu Garcia-Navarro, who was aboard the flight, described the experience on the social media platform X: “We sort of took a very steep ascent. I started praying because I was scared.” Flight tracking data from FlightAware confirmed the aircraft had nearly reached the runway threshold before executing the abrupt maneuver.
Multiple passengers reported feeling disoriented during the unexpected climb. One passenger told Channel 9’s Joe Bruno that the experience was “pretty crazy,” noting that observing fellow travelers’ reactions heightened the sense of alarm. Another passenger remarked, “About 20 minutes of going around in circles, but I will take that over hitting another plane on the runway.”
Despite the tense situation, the flight crew maintained professional composure throughout the incident. A passenger recounted: “I was looking out the window, thinking we were about to touch down in Charlotte, and then, nope. The pilot calmly announced, ‘Yeah, the runway was supposed to be vacated, but we have to make a change of plan.’ Sounds like a crisis was averted.”
