Depending on what you want for times and departures we service Hong Kong by way of ICN (Seoul, Korea). We have non-stops from ICN to LAX and ORD. If you are interested see our website for details and schedules. As long as you are in CASS you shouldn't have a problem. Click on either the polar or atlas thumbnails on the left side and that will take you to a page were you can see the "OAL jumpseat" request page.
