The transport ministry instructed nine low-cost carriers to improve safety standards and avoid prioritising cost-cutting.

South Korean authorities said on Wednesday they will change the concrete barriers used for navigation at some airports across the country after the Jeju Air crash that left 179 people dead.

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.

The two flight recorders on board a South Korean airliner stopped working before the jet crashed during an emergency landing and subsequent crash that killed 179 of the 181 people on board, officials said Saturday.

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.

The deadliest plane crash in South Korea's history is triggering a change at the country's airports. The BBC reports the concrete barriers that contain navigation systems at seven airports will be altered in the wake of the crash,
