Apologies if this has been asked recently, but the most recent thread I could find on this was from 2014.

I booked a roundtrip using miles. Now I need to cancel the outbound flight but keep the return flight. I've tried calling and chatting and texting with their support and each time it takes forever and I don't make any progress. Delta's representatives don't seem to know how to do it. They keep transferring me to someone else. Now they're telling me that I won't get any miles back if I cancel the outbound flight, which seems ridiculous.

Does anyone know what the actual policy is and how I should handle this? Thanks in advance.
