Thank you for the reply. Great idea about checking a guide book.
We do not have pass privs with Delta but are booking a return ICN-ATL-SLC via my wifes SkyMiles to use as a backup on getting home. Hopefully we won't have to use it.

Could you PM me a sample of what iddeals.com.uk standby availability looks like before I sign up as a member? If you could use a KAL flight like KE 018 LAX-ICN on April 6th 2008. Or any flight, I just want to see what the availability looks like it.

Thanks again for your help.
We don't need a hotel as we'll be staying with my Father In Law. We are considering going down to BUSAN for a couple of days and would just take the KTX train down.
