D'oh. My bad.

Which I've done, for that flight, and can attest there's nothing fun about sitting on a bench with strangers watching KE employees slowly set up for the night. If you can get your bags checked through and do not have to leave the secure area, there are shops and restaurants to pass the time. There's nothing but a very jammed, crowded convenience type store before security.
