US Airways Dividend Miles (Pre-FlightFund Merger) - Does Dividend Miles Dining Use I-Dine?

I went to the I_Dine website and looked at the airline partners for I-Dine. USAirways is NOT one of them. I attempted to monitor my I-Dine credits via the web by registering one of my credit cards that I use for USAirways miles, and I-Dine said they had no record of it.

So, does USAirways use I-Dine? If they do, is the program "different" from the other I-Dine airline partners?

I was told that US does use I-Dine. But, yes, US does have different partners.

For example, one of my favorite restaurants in D.C. - Bombay Palace is an AAdvantage Dining restaurant but is NOT a Divided Miles Dining restaurant.

I can't recall if this is iDine or not, but here is US's Dining Partner.

It seems like a no-brainer to register. I have no clue what restaurants are partners, but it always nice to see extra bonus miles appear out of thin space!
