Hello,

I booked a korean air award ticket for msp to hnl on delta. When I pull up the trip on my delta account it shows my korean skypass number as the frequent flyer program used. i tried removing on the app and on my computer. it wouldnt let me. I called delta and they said since it was booked with korean to call them. got on the phone with korean and they wouldnt take it off. Am i out of luck? i want to input my platinum medallion number so i can pick preferred seats.
