Following the deadly Jeju Air accident, the government ordered low cost carriers to reduce flight times, boost pilot training and expand maintenance crews.

South Korea plans to strengthen its oversight of low-cost carriers (LCCs) and impose strict penalties on airlines failing to meet enhanced operational safety standards, the government said Thursday, following last month's Jeju Air crash.

South Korean authorities are still investigating the cause of the recent air disaster at Muan International Airport. Some are blaming a concrete embankment at the end of the airport runway, which will now be removed.
