I always apply them to long legs only. On HSV-ATL-LAX, I will ask for them to be applied only to ATL-LAX as I don't want to burn one for HSV-ATL and then not have the long leg clear the upgrade.
I did burn an SWU on HSV-ATL once, but that was okay because most of them expired unused.
I expect to find a good use for all my remaining RUs.
