Despite United trying to buy USair 2 years ago, and their codeshare agreement this past year, and the DL/NW/CO alliance announced (also last year), I NEVER heard anything about the United-Delta partnership changing. Lots of rumors expecting it to be changed, but never anything definitive.

This is especially surprising since I believe the USair-AA codeshare (and FF redemption) was cancelled was because USair was willing to be bought by United (and it never got approved!).

I don't understand the logic of the DL-UA arrangement, but I'm glad it still exists.
