I would probably target putting the miles in AA or United account if that is the way to go. Since I do have at least minimal activities in those accounts.
I think [MENTION=296998]drminn[/MENTION] meant that you should continue to fly Delta, but credit your miles to a partner airline. For example, you could credit your miles to Flying Blue.
However, a downside of doing this is that you won't be able to realize any of the benefits of your DL status when crediting miles to a partner frequent flyer program where you don't have status. That means no upgrades, no preferred seats, no waived SDC fee, etc. You could change the program you credit miles to before you fly, though, if needed. I'm not sure what happens to preferred / upgraded seats, though, if you do this.
If you're worried about expiration of RDMs, one good way to keep miles active is to get a credit card with that other airline.
