South Korean authorities will increase their scrutiny of the country's low-cost airline sector, including tightening the criteria for MRO workers and enforcing stricter rules on network expansion.

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.

The nation’s transport ministry reviewed structures near airport runways after the deadly crash of a Jeju Air flight late last month.
