I ran across an interesting result in my search for discounted tickets on SBB. In every search I made, if I did not say that I had a HFC, the Supersaver option never showed. On the same search if I said I had a HFC, then the SuperSaver option would show. Take away the HFC and the SuperSaver would disappear.
According to my search results, it seems like the HFC is required to get the SuperSaver deal. I found no exceptions to this.
