In the past, I've always wondered if I reregistered in IDINE with a credit card that was already registered with another airline, which one would get the miles? I had to do it for this bonus, and the answer seems to be the new one.
Some of the airline affinity cards are automatically registered. Does anyone know if you can reregister them with another airline?</font>
To be safe, I would delete the credit card from the airline iDine program you want to drop, before adding it to the other program. I've never tried using the same credit card for two iDine programs, as I use a different card for AA and UAL, but I would assume by doing that you would only get credit for one airline, or none at all, but certainly not both.
