When I boarded a Swiss flight to Zürich on a business-class ticket a few months ago, I expected &mdash apart from the enhanced creature comforts &mdash on-time performance, meticulous attention to detail and cleanliness, and some sort of design sensibility. What I wasn&rsquot prepared for was a gourmet meal in the skies. There&rsquos no Swiss food beyond potatoes and melted cheese, I would have scoffed before the Airbus A330-300 left the tarmac in Delhi. Now my tummy knows better.
