I currently have Delta Silver Medallion status which expires soon, and this year I have almost 16000 Skymiles from flying. I am not planning on flying between now and the end of the year, and I want to know if anyone knows of any simple, easy ways to keep my Medallion/Skyteam Elite status (without actually flying or opening new credit cards, etc. either) so that it won't expire.
(I asked Delta if I could transfer family members' miles to my account to get to 25000 but they said I need miles from flights that I flew. I also specifically stay with Skyteam.)
If anyone could help me, I'd really appreciate it! Thank you!
