Korean Air ended its Seoul Incheon-Houston service on 29 October.
The carrier previously operated a thrice-weekly frequency with Boeing 777-200ER aircraft.
At the same time, it is adjusting the frequencies on a number of services, while upgauging capacity on two other routes.
Since 29 October, the airline raised capacity on the Seoul Incheon-Kuala Lumpur route by deploying Boeing 747-8Is in place of the 777s. For the Seoul Incheon-Taipei Taoyuan route, it deployed Airbus A380s to replace the A330s on one of the two daily services.
