Your fare remains the same but you get on the new flights you want provided they meet the routing rules of your original fare. It's really that simple.
Sorry, but this is completely wrong. The
United Website is very clear about how SDC works, and what's on that page matches my experience to the letter.

A higher fare class doesn't necessarily mean a higher fare. The fares could have changed in the interim making a higher fare class cheaper. As I mentioned previously, I've had an online SDC promise a $9 refund whilst putting me into a "higher" are class.
