As a nugget of information. I've searched for those flights on google flights, saw the price etc. Below it was showing where to book to get that price. I saw that Delta's site was giving the same amount. Long story short. I went to Delta's site in a new tab, searched for my flights and the price was $600 more for two people than the price showing on google flights.
Went back to google flights, searched for the flights and clicked Book with Delta link. It took me to Delta's site with the normal price, $600 less what the direct DL search gave me.
That is really f-up. Simple conclusion, don't go to Delta's website to search for a flight...
You need to get the KOREAN AIR RESERVATION NUMBER, not the Delta one. Delta will NOT be able to get you a seat on KE. The one and only time I flew GSP-ATL-ICN, I didn't get my seat for ICN at ATL until I went to the gate (and I arrived at ATL with like 1 hr 20 mins before departure), so it was a literal last minute seat assignment.
Get the KE res number and log into their website or call and select your seat. The Delta website might say it can get a seat, the Delta phone agent might say they can, but it won't stick and it's not guaranteed.
