4. Cooperative marketing agreements: Designated air carriers may, subject to the usual rules, enter into code-share or leasing agreements with airlines of both countries or with airlines of third countries. An optional provision allows for code-sharing between airlines and ground carriers. The EU-US Open Skies Agreement is an agreement on skiing air transport between the European Union (EU) and the United States (USA). The agreement allows every airline in the European Union and every airline in the United States to fly between every point in the European Union and every point in the United States. Both EU and US airlines can continue to fly to another destination in another country after their first stopover (Fifth Freedom Rights). Since the EU is not treated as a single area for the purposes of the agreement, this means, in practice, that US airlines can fly between two points in the EU as long as that flight is the continuation of a flight that started in the US (e.g. B New York – London – Berlin). EU airlines can also fly between the US and third countries that are part of the European Common Aviation Area, such as Switzerland. EU and US airlines can operate all cargo flights under seventh freedom rights, meaning that US airlines` net cargo flights can be made from one EU country to any other country (including another EU country) and EU airlines` net cargo flights between the US and any other country.
 Norway and Iceland acceded to the Agreement from 2011 and their airlines enjoy the same rights as EU airlines.  • International and domestic passenger transport amounted to 54.5 million per cent, of which 49 per cent was carried by foreign airlines. 21.
