Well I can now book SEA-ITH on United's website, with service being provided by US Air (SEA-PIT-ITH).</font>
I just tried that on ual.com and only got US Airways flights. I didn't see codeshares (UA flight numbers on US metal). Also, I could only find US published fares for SEA-ITH.
I think ITH also might be all Express now which would explain the non-codeshare flights. (I moved 5 years ago, and there was some mainline service then, but they have been phasing it out.)
