When they called, they were told that they could go the next morning. They called back and the nwa elite agent said they could fly to Zurich and then catch Swiss Air to Venice, which is what they did. But they had to leave for the airport immediately as they had to have paper tickets reissued. As it was, the flight was well into the boarding process by the time the paper tickets were printed.
They have contact information in the reservations, I would think it would be a courtesy that they should extend to their passengers to let them know of cancellations--especially for their elite members--they are Platinum(nwa).
