On June 22nd, Korean Air flight KE189 Boeing 737 reportedly experienced a pressurization system malfunction, resulting in a one-day delay in arriving at Taichung. Passengers described experiencing severe ear pain when the aircraft suddenly descended, with a doctor explaining that the pain was due to a sudden increase in external pressure pushing into the relatively lower pressure middle ear cavity. Many passengers reported ear pain and dizziness upon landing, and medical experts recommend techniques like pinching the nose and swallowing to help balance inner and outer ear pressures and alleviate pain.
