That too bad jersey gyal. I have done some web surfing to see if there were any regulations covering my situation for cancelled routes. The best I could come up with is the the airlines do not have to set us up with airfare on a different carrier. They usually do it for customer relations.
I am going to call them again in a week or two. I have a feeling with the difference between what I paid for the A.J. and what USAir's rate it won't happen.

Good Luck with yours
