Thread: Open Skies Agreement

No, the EU is not a country, but it is not 'only a trade bloc' either. In many aspects (civil aviation, for example) the EU has as much power as the Federal Government in the US. In other aspects it holds a lot less (external relations), and yet in others it holds a lot more (Common Agricultural Policy). In many things, and air transport is one of those things, the EU has to be considered as a single country.

Within the EU there is no difference between a purely domestic (MADBCN) or intra-EU flight (MADCDG), so it would be legally questionable to allow US airlines to fly between EU destinations but not routes entirely within a member-state. So, yes, if EU airlines are allowed to fly domestic flights within the US, US airlines will be allowed to fly domestic flights within the EU, irrespective of whether it is member-state-domestic or EU-domestic, since that distinction doesn't exist or is allowed in European Law.
