South Korea's Air Busan will not allow passengers to keep power banks in luggage stored in overhead cabin bins, in what on Tuesday it called a preemptive measure after one of its planes was engulfed in flames last week.

A South Korean airline is introducing a ban on carrying power banks in hand luggage. This follows a fire on one of their planes on the runway in January. Air Busan, a South Korean airline, has announced a restriction on carrying power banks in hand luggage stored in the overhead compartments.

Hong Kong expert says expansion of measure to other airlines will depend on further risk assessments by trade groups and carriers.
