SWISS AIR RESPONDS:

We regret that the passenger had an unpleasant experience and understand her frustration. However, the review of the case showed that she was denied transportation, as she could not present all necessary travel documents for her flight. Yet, as stated in our conditions of carriage, it is the passengers’ responsibility to present themselves at the gate in possession of all required documents/ visas. Generally speaking, should there be any clarifications needed for such documents, it is the embassy or the local consulate that would need to be addressed before travelling.
