I would be using Star Alliance with USAIR miles. I believe that USAIR now lets you do one way awards, although I am not sure about internationally. They used to charge you the same miles RT as one-way.

Yes, I believe I will just have to bite the bullet and get on the phone. I have looked at routes (PIT-CPH-PIT), and it looks like I would be USAIR or UA on the domestic leg and either LH or SK or both on the international leg(s)...UA was also an option, but I would much rather a foreign carrier such as SAS or Lufthansa for the international portion....BUT perhaps beggars can't be choosers...and I have no real ff status...my miles aren't "real" air miles.
