Korean Air Skypass - Can I avoid Q class CNX-ICN-ATL?

I want to fly CNX-ICN-ATL and get miles on my Delta account. On KE website my only booking choices for economy are "normal fare" which gives me Y class tickets (too expensive) and "lowest fare" which gives me Q class tickets (no mileage accrual to my Delta account). KE does have "discounted economy" booking classes (E, L , H, T, K, M), does anyone know a way to pay a little more for the economy tickets and qualify for one of these classes? I tried booking this flight on the Delta site but it would not show me the KE flights. Thanks.

You can do it through an agent

Call center should be able to do it. Use ITA to find the exact fare basis first though...

I recently booked an all T fare via Korean Air reservations. They were able to work some magic that other travel agents did not seem to be able too. Something about fare restrictions.

I did have to pay at a local KE office. I believe the reason is that phone reservations can only take Korean credit cards with PIN.
