I am trying to book my trip next October. My understanding is Mileage Plan allows a free stopover and open jaw.

Since the award schedule is not out yet when I booked my outbound, I called in today to add my return and ran into some complication, I wonder if anybody can help me to see the light. My schedule is as follow

1. Outbound October 2023, SJC to SEA to YVR to HKG (Stopover) to KUL , with Alaska and Cathay.
2. Inbound in November 2023: HKG to ICN to SEA to SFO, with Korean Air and Alaska.

I was told I cannot add the return from HKG since my outbound destination is KUL. If I want to use 60k with Korean Air to return, I have to drop KUL or I pay the full 120k for the return flight as an one way ticket.

I thought an open jaw is allowed.

Please advise, thanks.
