I was surprised to discover that Korean Air, while being a major airline, is an operator of corporate jets. I’m not sure how an airline ends up in the bizjet market but they have. They have Globals, G650s and BBJs. One of the G650s was in SEA recently but I didn’t have an opportunity to see it. However, I did get the BBJ on one of its visits to BFI. It was stopping at BFI before making a direct run back to Korea. It is quite a nicely painted jet. Lots of the windows are blanked out on the front fuselage. A check on their website shows this is where some sleeping seats are installed. Plenty of smaller accommodation at the back for your lackeys to use while you rest up front if you like.
