The 62-year-old man, who suffered a “escalating medical crisis” on a flight belonging to the American Airline, died after the crew filed a lawsuit saying that he “sought medical assistance until the plane landed, then took a taxi to the gate, and all other passengers were exhausted.”
The Colorado Federal Court filings to American Airlines and the envoy airlines of the local carrier seek at least $75,000 in damages after the death of John Cannon, a Kentucky passenger who was traveling to Durango-la-Plata County Airport.
“The premature passage of John William Cannon on April 29, 2023 was the direct and proximity of the defendant’s negligence and negligence,” reads the lawsuit filed this week on behalf of his son.
American Airlines and Envoy argue that they are neglecting to cause the death of the cannon by failing to provide reasonable first aid on board the aircraft and showing signs of extreme physical distress placed on the aircraft, saying, “failed to prioritize John William Cannon in the decoration process.”

American Airlines told Fox News Digital it is “considering the complaint.”
The lawyer said until his death, Cannon first boarded a plane from Louisville to Dallas, experiencing “John suffered from a Cincopal event during flight and/or hair removal,” or loss of consciousness.
“After suffering from the event, John was saved by the floor of the jet bridge at Gate 12 at Terminal B at Dallas-Fort Worth International Airport. Two minutes and 15 seconds later, John was released and made a connecting flight,” it continued.

“In spite of the escalation of Cannon’s medical crisis, the squadron of AAL4896 delayed the request for medical assistance until the aircraft landed, and took a taxi to the gate, causing all other passengers to shed,” the lawsuit allegedly.
“It was called emergency services and reported that Cannon was in and out of breathing consciousness,” he added, and “a firefighter from the Durangola Plata fire contacted Cannon and began oxygen treatment along with members of the EMS team before it was removed from the aircraft.”
