Due to open skies agreements between EU countries, any EU based carrier can operate any route they wish within Europe, this is something the LCCs have put to good use, with them operating multiple bases across Europe.
However is the same true for flights operating to destinations outside of the EU? Could an EU airline based in say France operate flights from its German base to a non-EU destination such as Turkey or even the US?
Was this not an issue that was raised during the Air France / KLM merger, because the airline was no longer dutch based there would be a possibility of them losing the rights to operate to the US from Netherlands.
What are the rules regarding this, and are there any airlines that are exempt due to country-country agreements, specifically with the US?
