I understand the basics: Get miles for each dollar you charge on your registered credit card at participating restaurants.

But for some reason I can't get it to work right. I enrolled on the main site(Idine.com) and put in my Dividend Miles account and 2 credit cards. It accepted everything and said I was ready to go. I also wanted to earn Onepass miles and United miles, so I enrolled through their websites with different credit cards. Those 2 accounts are fine, but the main Idine account just won't work for me.

When I log in, it lists my account info, and says "Dividend Miles", but says there are no credit cards registered. So when I click on "Add" a credit card, it just takes me to a page to join Idine Prime. I don't want to join Idine Prime. But it won't take me to a page to add a credit card.

So I called the Idine phone number, and the woman said that Idine website is just to earn discounts on dining, and if you want to earn airline miles you must go through the airlines site. But I don't think that is right. The Idine site says that I am signed up to earn Dividend miles, but again, won't register a credit card. And all the restaurants list how many miles per $ I would earn there.

I know I can give up and just go through the USair website, but now I am really interested to figure out why I can't make this thing work.

Can someone explain my problem with the Idine website?
