Why buy or Orbitz?

I'm not necessarily buying from them, only using them to see various routings and schedules.
I see where I can get a round trip KE air ticket for around $1600 in business class on KE, but looking at the schedule there is a 12 hour layouver in ICN. Don't think I want that.

tol- good idea. I am also looking at F, but not sure if I want to spend the extra 1K, but it's a possibility.

DeltaFlyingProf- thanks for the advice on the flights/seats. Yes I'm wondering also what kind of equipment they are flying to LAS. Could go one of two ways, new flight new equipment, or new flgiht old equipment to check demand.
