Ahhh,
but if independant countries got together and did what you are proposing, by claiming all of Europe to be one country for the purposes of airnavigations, then the USA would do similar with NAFTA.
Then the spanish airline (I forget the spanish national airlines name at this time of night) couldn't operate their little hub in Miami onward to Latin America and all those little 737/a320s (I forget which I saw this week in Miami) would have to go back to Europe.
The EU is NOT one country, and untill all the nations are abolished and replaced with brussels (who needs a parliment anyway?) you can't make those claims, and you are simply deluding yourself. The only thing that EU can negotiate as a block is 5th freedom rights (which is what is talked about when they talk open skies).
Cheers
