If the A340 product is so unpopular at Zurich, the Swiss cannot go anywhere, as the A340 is the longhaul plane used by Swiss International, the airline that followed on after Swissair. The Swiss timetable shows that they operate ZRHHKG sx times weekly.
Singapore flies daily to ZRH from their city, as do several other Asian carriers. The CX iinflight product is at least as good as the Singapore Girls. Or is ZRH a route to leave for CR Airways or Oasis to do?
