abstract:The portmanteau NYLON, also spelled NYLon or, less often, NY-Lon, starts with the concept of New York City, USA, and London, England, as twin cities — the financial and cultural capitals of the Anglo-American 'world' — and takes the concept a step further, treating the two cities as "a single city separated by an ocean". There is a community of high-earning professionals who commute with extreme frequency — sometimes several days in a given week — between New York and London on its particular transatlantic air route.
