Power Bank Rules on Jeju Air

Korean airlines, including Jeju Air, apply strict rules on top of the ICAO standard, and since 26 January 2026 power banks may not be used on board:

  • Keep power banks with you, not in the overhead bin.
  • Cover the terminals or keep each one in its own plastic bag.
  • A maximum of two per passenger; no charging devices from a power bank during the flight.
  • Never pack power banks in checked bags.

Safety After the Muan Accident

On 29 December 2024, Jeju Air flight 2216, a Boeing 737-800, crashed at Muan airport, killing 179 people. As of August 2026 the final accident report had not been published. Korea’s transport ministry admitted in January 2026 that the concrete localizer structure at the end of the Muan runway breached safety standards, and all of Korea’s 737-800s were inspected after the crash.
