If you can‘t get through to Swiss - call Swiss.com support 043 547 99 19. The person I spoke to told me it isn‘t the flight support line, but was able to help nevertheless. I called early.
Any luck? We've also been calling this morning. We wait a few minutes with the music playing, hear a ringing sound as if the call is transferred to a rep, then the call drops.
No luck today. Same thing happening to me.
I'm guessing that there is only a skeleton staff on the weekend. Will try tomorrow.
