Jeju Air, South Korea's largest low-cost carrier, is facing a crisis after a deadly crash on December 29th killed 179 people, leading to an investigation and a travel ban on its CEO, Kim E-bae. The crash marks South Korea's worst air disaster in nearly thirty years, prompting government scrutiny of the airline's operations, including frequent flights and outsourced maintenance.
