I don't know if this has been covered elsewhere, but I am curious as to whether members belong to more than one I-dine program, and how that might work.

For instance, I get Delta SkyMiles for I-dine when I use one credit card, and I signed up for UPromise which also has an I-dine feature, and I know CO and NW and others all do, too.

Many of the restaurants listed for DL have limited earning (usually one time per month). I can only assume that the others have similar limitations. Can you, though, use DL one time, UPromise one time, NW one time, etc.?

I am curious to know how this would work, and to see how many others belong to more than one I-dine program.

Thanks,
Stevekoe
