Some 30,000 feet over the Pacific, a long-haul flight from Dulles turned into a nightmare that never ended for one D.C. family. Porscha Tynisha Brown, 33, collapsed and died on Korean Air Flight 94 from Washington Dulles to Seoul after what her relatives say was a preventable medical emergency in the cabin. Her estate claims flight attendants handed her an oxygen mask that was never connected to the aircraft’s oxygen tank, leaving fellow passengers scrambling to keep her alive as the crew stood by. The jet diverted to Osaka, where Brown was taken to a hospital near Kansai International Airport and pronounced dead, as per DocumentCloud.
The allegations are laid out in a complaint filed March 27 in the U.S. District Court for the Eastern District of Virginia. The filing says Brown collapsed roughly 12 hours into the approximately 15.5-hour flight and was transported to Rinku General Medical Center after the emergency landing. According to the complaint, the oxygen mask provided to Brown was not hooked up to an oxygen tank and airline staff did not effectively use the onboard automated external defibrillator, as detailed in DocumentCloud.
Passengers Stepped In as Crew Faltered, Lawsuit Says
“At no point in time did the Korean Air flight personnel attempt to take charge,” the complaint asserts, saying medically trained volunteers and other passengers were left to figure out the AED and medical kit themselves. According to the filing, the AED repeatedly announced “shock advised,” but untrained bystanders did not press the shock button because crew members failed to give instructions. Passengers also administered epinephrine from the onboard kit, which did not reverse Brown’s symptoms. The complaint states that Brown’s Japanese death certificate lists her cause of death as “acute cardiac failure.” You can read the document via DocumentCloud.
Family Sues as Lawyers Blast Airline’s Response
Brown’s estate is suing Korean Air for wrongful death and asking a jury to determine damages. Attorney Hannah Crowe, who represents the estate, described Brown as “a really remarkable young woman,” while co-counsel Darren Nicholson said the crew’s conduct “shocks the conscience,” according to The Independent. The lawsuit alleges a series of failures, including misuse of the oxygen equipment, delays in declaring a medical emergency, and delays in diverting the aircraft, which the estate argues cost Brown her life.
In-Flight Medical Crises Are Rare, but Stakes Are Enormous
Serious medical emergencies in the air are uncommon, but they are a known risk of commercial flying. A 2025 multinational cohort study in JAMA Network Open found about 39 in-flight medical events per 1 million enplanements, or roughly one incident every 212 flights, and reported that cardiac problems are a frequent reason planes divert.
Industry guidance from the International Air Transport Association outlines how crews should respond to a death on board and highlights the importance of continuing CPR and using AEDs clearly and correctly until medical professionals take over. That framework underpins the estate’s argument that standard procedures and proper equipment use might have made a difference in Brown’s case. Whether the complaint and the lawyers’ claims hold up will be decided in court.
The case is pending in federal court in Virginia as Brown’s family presses for answers and damages. Korean Air did not respond to a request for comment, The Independent reported.
