Korean Air is launching a codeshare partnership with Royal Brunei Airlines starting September 4. The codeshare agreement will allow both airlines to market service on each other's airlines’ flights under their own flight number.

Under the new deal, flag carrier Korean Air will sell seats on the 5-hour Incheon-Brunei route of Brunei Darussalam's national flag carrier airline, under its flight number as a marketing carrier, without directly launching the route.

The route is operated four times a week on Tuesday, Thursday, Friday and Sunday.
