A passenger alleges that a hot cup of tea slid off a tray, landed onto her lap, and burned her when she flew on a Korea Air Lines-operated flight from New York to Seoul. The woman filed a lawsuit against the airline in Dallas federal court on July 30.

In her complaint, Pyonghae Helen Yun, who is represented by Ladd Sanger of Dallas’ Slack & Davis, cites the airline’s alleged liabilities for her spilled-tea-related injuries. She makes her claim under a multilateral international treaty known as the Montreal Convention. A provision of the Montreal Convention requires international common carriers to assume liability for passenger injuries due to accidents, unless the airlines can prove that the events were solely due to the negligence or wrongful act of another party.
