I have two tickets that were booked by DL DM agent. I used GUCs for OKC-ATL-ICN-ATL-OKC then SM for KE ICN-HKG-ICN. (All segments are biz.)

I should have no problems getting KE EBP in HKG for the flight back to ICN, but what happens with my DL ticket on to the USA?

I have not flown out of ICN as the city of origin (for several years now) so I would like to know if DL uses EBPs for #26 to ATL.

On the flip side, if I fail to get the KE EBP for ICN-HKG while in ATL waiting for DL #27 to ICN I hope the Wifi is working. Any problems to report of late on this route (ATL-ICN)?
