Yet another round of aviation negotiations has been opened between the European Union and the United States. The negotiations originally started in 2003 after the European Court of Justice declared that bilateral 'open skies' deals between the US and individual EU Member States were illegal. Despite the negotiation in 2005 of an EU-US text designed to replace the bilaterals, the two blocks have been forced back to the negotiation table following a US announcement that part of the 2005 deal could not be implemented. The European Commission has declared that it cannot continue to refrain from requiring termination of the illegal bilateral deals, thereby emphasising the urgency for a EU-US agreement to be reached.
