Your wife doesn't need to fly to Korea unless Korea is her destination. My desired destination is JAX. I don't want to travel until September, so I'm not in a rush to buy a ticket, but PVG-HND-DFW-JAX has wide availability for $750. And, if I want to do a shorter trip, I can swing PVG-JFK-JAX for $2000.
