An 82-year-old passenger says he warned American Airlines crew members about the person seated beside him before she allegedly attacked him during a flight from Florida to North Carolina. More than two years after the alleged incident, the dispute has become a federal lawsuit against the airline, while the passenger accused of the attack has faced separate federal criminal proceedings.
Walter Loughney alleges that airline employees knew he was uncomfortable with his seatmate and that he asked to be moved before the alleged assault occurred. His lawsuit claims the airline failed to take appropriate action and that he suffered serious injuries during the confrontation.
The allegations remain unresolved, and no court has determined that American Airlines was responsible for Loughney’s injuries.
The Warning Before Takeoff
The incident began on May 16, 2024, aboard American Airlines Flight 2485 from Palm Beach International Airport to Charlotte Douglas International Airport.
According to Walter Loughney’s federal complaint, he was sitting in seat 18D when Allisen Elizabeth Werner took the adjoining seat, 18E.
Loughney alleges that Werner began behaving disruptively after boarding, including loudly singing and bellowing to herself. He says her behavior immediately concerned him.
Rather than simply remaining in his seat, Loughney says he approached airline personnel and asked multiple times whether he or Werner could be moved.
The complaint alleges that American employees told him there were no available seats and did not relocate either passenger.
That detail forms the foundation of Loughney’s case.
His argument is not merely that another traveler unexpectedly became violent. He contends that the airline had received a warning beforehand and therefore had an opportunity to respond.
The allegations remain disputed and have not been tested through a civil trial.
The Alleged Attack in the Cabin
According to the lawsuit, the situation escalated after the aircraft was airborne.
Loughney alleges that Werner suddenly struck him repeatedly and severely beat him, causing injuries to his head and brain.
He further alleges that a flight attendant was standing within arm’s reach during the incident but failed to intervene or otherwise defuse the confrontation.
The complaint claims the injuries went beyond temporary discomfort. Loughney alleges physical injuries as well as emotional distress and continuing anxiety about air travel.
These are allegations contained in the plaintiff’s complaint, not findings by a judge or jury. The civil court has not issued a final ruling establishing American Airlines’ liability.
What Happened After Landing?
When Flight 2485 reached Charlotte, Werner was arrested and removed from the aircraft, according to reporting and the lawsuit.
The incident subsequently moved into the federal criminal system.
A federal grand jury indicted Werner in February 2025 on two assault counts. She was formally charged in March, but later failed to appear for a scheduled court proceeding and was reported as a fugitive.
That criminal proceeding is separate from Loughney’s lawsuit against American Airlines.
This distinction matters. The criminal case concerns allegations against Werner, while Loughney’s civil action asks whether the airline can be held financially responsible for its own alleged conduct.
Federal aviation assault statute, 49 U.S.C. § 46506 explains when certain federal criminal laws apply to conduct aboard aircraft.
Why American Airlines Was Sued
Loughney filed his federal civil lawsuit against American Airlines on May 5, 2026, in the U.S. District Court for the Southern District of Florida.
The case is Loughney v. American Airlines, Inc., No. 9:26-cv-80516.
The lawsuit alleges negligence and argues that American failed to take adequate measures to protect him despite the concerns he allegedly communicated to the crew.
The complaint also alleges that the airline owed him a heightened duty of care and failed to respond appropriately before and during the alleged assault.
Loughney is seeking damages and requested a jury trial.
Federal case docket for Loughney v. American Airlines provides the publicly available filing information for the lawsuit.
The Lawsuit Initially Hit a Roadblock
The case did not immediately move into a full examination of the alleged assault.
On May 6, 2026, the initial complaint was dismissed without prejudice after the court identified an issue concerning the plaintiff’s citizenship information, which was relevant to the federal court’s diversity jurisdiction.
That procedural dismissal did not constitute a finding that the alleged attack did not occur or that American Airlines was not negligent.
A dismissal without prejudice allows the plaintiff to correct the identified pleading problem and continue pursuing the claim.
Later reporting indicates that an amended complaint was filed and that American Airlines subsequently responded to the litigation. The case has therefore continued beyond the initial dismissal.
The Case Is Still Moving Through Court
The latest publicly indexed case information shows that the litigation has continued into September 2026.
A docket record for American Airlines lists a protective order filed in Loughney v. American Airlines on September 25, 2026.
That is a significant procedural development because protective orders commonly arise during litigation when parties are dealing with discovery or information subject to confidentiality restrictions.
However, the existence of a protective order does not establish that American Airlines is liable, nor does it resolve the factual dispute over what the flight crew knew or should have done.
The case therefore remains unresolved.
The latest publicly indexed federal docket information shows the September 25 filing.
The Legal Issue Behind the Case
The most important legal question is not simply whether one passenger assaulted another.
It is whether the airline’s alleged response before and during the incident amounted to negligence.
A negligence claim generally requires examination of issues such as duty, breach, causation and damages. In this case, the factual dispute could center on whether American employees had enough information to recognize a potential safety problem and whether reasonable action could have reduced the risk.
The evidence could become particularly important.
The parties may need to examine crew reports, communications, passenger accounts, seating information, medical documentation and other records relevant to what happened before, during and after the alleged assault.
The court will ultimately have to evaluate the evidence rather than simply rely on the allegations contained in the complaint.
Federal Law Also Addresses Violence on Aircraft
The incident occurred within a broader federal aviation safety framework.
Under 49 U.S.C. § 44701, the Federal Aviation Administration has authority to prescribe aviation safety regulations and minimum safety standards for air carriers.
Federal law also specifically addresses physical and sexual assaults aboard aircraft.
49 U.S.C. § 46318 provides for federal civil penalties when an individual physically or sexually assaults or threatens certain people aboard a civil aircraft, including another individual on the aircraft.
That provision is relevant to the wider legal environment surrounding passenger violence, although it does not itself decide whether American Airlines is civilly liable to Loughney.
The FAA Continues to Track Unruly Passengers
The lawsuit also arrives during continuing federal efforts to address dangerous behavior on commercial flights.
The FAA investigates unruly-passenger incidents reported by airline crews and can pursue civil enforcement. Serious cases can also be referred to federal law-enforcement authorities.
The agency says the rate of reported unruly-passenger incidents has fallen substantially from the extraordinary levels recorded in 2021, although disruptive and violent incidents continue.
The FAA’s current statistics and enforcement information are available through its official Unruly Passengers database and guidance.
Federal agencies have also established procedures for referring appropriate unruly-passenger cases to the FBI for potential criminal prosecution.
A New Federal Requirement Highlights the Issue
Congress has also taken steps to reinforce passenger awareness of the consequences of violence aboard aircraft.
The 2024 FAA reauthorization legislation directed the FAA to establish a task force addressing suspected violations involving interference with crew members and other dangerous conduct. The legislation also called for passenger briefings to state that federal law prohibits assaulting or threatening individuals aboard aircraft and interfering with crew duties.
That broader legal framework does not determine the outcome of Loughney’s lawsuit, but it demonstrates why violence aboard commercial aircraft is treated as an aviation safety issue rather than simply an ordinary passenger dispute.
The Separate 2026 American Airlines Assault Lawsuit
Another American Airlines passenger-assault lawsuit reported in 2026 should not be confused with Loughney’s case.
That separate lawsuit concerns a different passenger, a different flight and a different alleged incident.
Keeping the cases separate is important because the similarity of the allegations can easily create the impression that they are part of the same proceeding.
They are not.
The Loughney litigation concerns the May 2024 Flight 2485 incident involving his alleged assault by Werner and his subsequent negligence claims against American Airlines.
What Happens Next?
As of September 29, 2026, no final judgment has determined whether American Airlines is liable for Loughney’s alleged injuries. The lawsuit remains pending in federal court following the filing of an amended complaint and subsequent litigation activity.
The case is expected to proceed through further discovery and court proceedings as both sides present evidence concerning the alleged warnings, the crew’s response and the circumstances surrounding the incident.
The court will ultimately determine whether Loughney’s allegations establish the legal elements of his negligence claims and whether American Airlines has any liability for the injuries he alleges.
For now, the case remains unresolved, while the separate federal criminal proceedings involving the passenger accused of the attack remain distinct from Loughney’s civil claims against the airline.
