Passenger Allegedly Explodes at United Flight Attendant, Calls Her “Fat and Ugly”

A United Airlines (UA) flight from Brussels (BRU) to Chicago O’Hare (ORD) was met by law enforcement after a passenger allegedly directed abusive remarks and made violent threats toward a flight attendant during the transatlantic journey on July 20.

The confrontation unfolded while the Boeing 787-10 Dreamliner was en route across the Atlantic. Cabin crew managed the situation in flight before police boarded the aircraft upon its arrival in Chicago.

United Airlines Passenger Accused of Threatening Flight Attendant

The incident occurred on United Airlines flight UA973 operating from Brussels Airport (BRU) to Chicago O’Hare International Airport (ORD), according to details reported by PYOK.

Passengers who witnessed the exchange said the woman believed a flight attendant had been discourteous throughout the flight and responded by confronting the crew member.

According to eyewitness accounts, the argument escalated into personal insults. One passenger claimed the flight attendant was called an “ugly ass b**ch,” while another recalled hearing the woman say, “If you’re going to be fat and ugly, you’re in the wrong profession.”

Witnesses also alleged that the passenger threatened violence, saying, “I will f**k her up… I understand why passengers get violent with flight attendants.”

These descriptions were shared publicly by passengers after the flight and have not been independently verified by either United Airlines or law enforcement authorities.

Flight attendants worked to calm the situation during the flight while simultaneously notifying authorities before landing. Police officers were waiting at the arrival gate when the aircraft reached Chicago O’Hare.

Passengers Shared Details After Landing

Information about the incident surfaced after travelers discussed the event on Reddit.

One passenger asked whether anyone knew what happened to the woman involved, noting that police officers were waiting on the jet bridge but passengers were not allowed to remain and watch the outcome.

The individual admitted they were simply curious, prompting other travelers who had been seated closer to the confrontation to describe what they had witnessed, including the remarks that later spread across social media.

United’s Brussels-Chicago Service

United Airlines operates flight UA973 daily between Brussels Airport and Chicago O’Hare International Airport.

The 6,675-kilometre (4,148-mile) route is served by the Boeing 787-10 Dreamliner and has an average flight time of approximately eight hours. Flights arrive at Terminal 5 in Chicago.

The service is also marketed through codeshare agreements with Air Canada, Lufthansa, Swiss International Air Lines, Austrian Airlines, and Brussels Airlines, allowing passengers to connect through multiple European and North American destinations.

Federal Law Covers Threats Against Flight Crews

Threatening or interfering with flight attendants is a federal offense under Title 49, Section 46504 of the United States Code.

The law applies to anyone aboard a US-registered aircraft operating within the special aircraft jurisdiction of the United States, including flights over international waters. A person may face prosecution if assault or intimidation interferes with a crew member’s ability to perform their duties.

Convictions can result in fines and prison sentences of up to 20 years. Federal law also permits fines of up to $250,000, while cases involving dangerous weapons can carry significantly harsher penalties, including life imprisonment.

Prosecutors are not required to prove that a passenger specifically intended to intimidate the crew. Instead, they only need to demonstrate that the individual’s actions interfered with the normal performance of cabin crew duties.

FAA Can Pursue Civil Penalties Separately

In addition to potential criminal charges, the Federal Aviation Administration (FAA) has authority to pursue civil enforcement against unruly passengers.

Under the FAA Reauthorization Act, the agency may seek penalties of up to $43,658 for each violation, with multiple violations possible during a single incident. The FAA adopted its zero-tolerance policy in January 2021, replacing warning letters with monetary penalties.

Passengers found responsible for disruptive behavior may also lose TSA PreCheck privileges and be placed on an airline’s internal no-fly list.

Unruly Passenger Cases Remain a Concern

Since late 2021, the FAA has referred more than 310 serious unruly passenger cases to the FBI for possible criminal prosecution.

Although incident rates have fallen by more than 80% from the record levels seen in early 2021, airlines still reported 2,102 unruly passenger incidents during 2024, slightly higher than the 2,076 recorded in 2023. During that period, the FAA opened 512 investigations, initiated 402 enforcement actions, and proposed $7.5 million in fines.

Industry-wide figures released by IATA show a similar trend. Based on 93,107 reports submitted by more than 140 airlines, there was one unruly passenger incident for every 355 flights in 2025, compared with one for every 307 flights in 2024. Failure to comply with crew instructions continues to be the most frequently reported form of disruptive behavior.
