Korean Air Lines Co., South Korea's largest national flag carrier, said Tuesday that it will enhance security for flights to the United States starting this week.

Under the measures set to begin Thursday, all passengers on U.S.-bound flights from Incheon International Airport are required to go through extra security screenings when checking in and boarding their flights, the airline said. (Yonhap)
