The infrastructure is excellent everywhere. Business visitors may move easily from one part of the country to another by domestic airlines or by modern fast trains. It is Scandinavian Airlines System's consolidated hub for U.S.-bound traffic. Copenhagen also has a modern seaport catering to freight vessels as well as to luxury cruise liners. Other major ports are at Esbjerg, Aalborg, Aarhus, and Fredericia.
Telecommunication services are highly developed.
Denmark is a central link for satellite communications between the former East Bloc and western Europe and the United States. Its telephone systems provide first class digital service, and several cellular system providers offer excellent trans-European and worldwide mobile communications. Many also speak German and French. For expatriates working in Denmark, rental of a house or an apartment is the most common arrangement. Housing costs are well above those in major American cities.
