I haven't flown Delta since 2006 but I keep earning miles through Hilton Honors. When I saw that I had 10,301 miles I decided that it was time to cash out and cancel my account. When I went to the Skymiles marketplace it told me I wasn't able to redeem for anything because "SkyMiles Marketplace is a benefit for Diamond, Platinum, and Gold Medallion® Members & Delta SkyMiles® Credit Cardmembers from American Express®." I have no reason to keep earning miles and I don't plan on flying anytime soon but I don't want to just forfeit the miles when I cancel my account. Is there any other way for me to use them? Any way to sell them? Any way to transfer them to another program? Any ideas? Thanks!
