Plans are afoot to cut transatlantic fares to as little as £66 return.  Passengers travelling to the U.S. and Canada could enjoy the type of low-cost fares that have revolutionised European air travel.  Executives at Cologne-Bonn airport in Germany say they are in 'serious' talks with several American airlines to offer budget return flights to the U.S. for just £66 starting by 2005.  The flights would be open to tourists anywhere in the world – as long as they have access to the Internet – though UK customers would first have to get to Germany.  'The plan is for all tickets to be sold online – no refunds, no frills, no fancy lounges and trimmed back in-flight entertainment and meals.  Locations being touted include New York, Boston and Washington together with mid-western U.S. cities and destinations in Canada.
