WASHINGTON— A United Airlines (UA) gate agent at Washington Dulles International Airport (IAD) was knocked unconscious after a violent assault by a passenger angered by a flight delay to Atlanta (ATL).
The accused, Christopher Stuart Crittenden, 54, pleaded guilty in federal court to interfering with security screening personnel — a serious felony that may lead to 10 years in prison and a $250,000 fine, PYOK reported.

United Passenger Pleads Guilty
The March 13 incident unfolded at Washington Dulles International Airport (IAD), where Crittenden was set to board a United Airlines flight to Hartsfield-Jackson Atlanta International Airport (ATL).
After learning about a delay just before the 5:10 PM scheduled boarding, he became irate, verbally abusing the gate agent while collecting his boarding pass.
Despite the agent’s apology and effort to de-escalate the situation, Crittenden escalated his aggression. He shouted profanities, moved around while yelling, and tore up his boarding pass before demanding another. At this point, the agent notified the flight’s Captain, suspecting the passenger was intoxicated.
The Captain evaluated Crittenden and denied him boarding due to concerns about his behavior and possible intoxication. Moments later, Crittenden returned to the counter, asked the gate agent, “Do you want this?” and struck the staffer with a closed fist in the jaw. The blow knocked the agent unconscious, causing them to collapse.

Legal Fallout and Criminal Charges
Following the assault, Crittenden attempted to punch a second gate agent but missed. Multiple passengers intervened and restrained him until law enforcement arrived.
Due to the role of gate agents in performing security duties—such as verifying boarding documents and controlling access to secured zones—Crittenden was charged under federal law for interfering with security screening personnel rather than facing a simple assault charge.
On July 10, Crittenden pleaded guilty under a plea deal. He agreed to pay $15,000 in restitution to the victim, who required emergency treatment and follow-up dental care due to facial injuries.
The Federal Aviation Administration (FAA) has reported 835 incidents involving unruly passengers so far in 2025. While this marks a significant decrease from 2,102 cases in 2024, the current rate remains concerning, averaging 2.0 incidents per 10,000 passengers as of the week ending July 6.
Airlines, federal authorities, and airport operators continue to reinforce policies that prioritize the safety and well-being of front-line staff.
Assaults against gate agents, flight attendants, and other aviation personnel are met with strict legal action, reflecting their integral role in transportation security.

Broader Implications for Passenger Behavior
The case underscores growing legal accountability for disruptive passenger behavior. As U.S. airports experience record volumes, the aviation industry is increasingly vigilant about zero-tolerance policies.
Any attack against employees performing security-related duties, such as gate agents, is considered a federal offense.
Passengers are urged to follow airport conduct rules, remain calm during delays, and avoid confrontations that could escalate into criminal offenses.
