this was the worst hack ever - NO one, not even people in the US (let alone the Swiss Air people) - seemed to believe me when I showed them that these flights were eligible for C+ on day of travel. The people in the SkyClub looked at me as though I was an alien from another planet. I finally got C+ both ways, cleared at gate - but first guy (in the U.S.) made it seem as though he was doing me a favor (????). Next time I'll just pay a bit more and book on DL directly.
