Common Aviation Agreement
Andrew Haines, director general of the Civil Aviation Authority (CAA), the UK`s aviation authority, has proposed that the UK be able to negotiate individually with ECAA member states if an agreement with the EU as a whole cannot be reached. This could allow the UK to circumvent some EU rules and even the case law of the ECJ. The question of Gibraltar could also be circumvented if no agreement was reached with Spain. However, it is not certain that this is compatible with EU law. In addition, it would be a very complex and tedious task to conclude agreements that offer the nine freedoms. In addition, EU agreements with third countries would no longer apply as soon as the UK is outside the EU trade agreement. AACO responded to this consultation by focusing mainly on two major issues that require the attention of EU regulators, one being aviation infrastructure (airport congestion and air traffic management) and the other the relatively high tax environment imposed on the air transport sector. However, there is no guarantee that international aviation supervisors would accept the CAA regulatory standards, particularly if they decide to deviate from the current EASA rules. This carries the risk that British airlines will be completely cut off from flights to certain countries. However, horizontal agreements do not offer the same degree of freedom as in the AEEC.
For example, the open ski agreement between the US and the EU misses out the eighth and ninth freedoms for EU airlines.

The WEEE Agreements were signed on 5 May 2006 in Salzburg, Austria, between the EU and certain third countries. It was built on the acquis communautaire of the EU and the European Economic Area. The ECAA liberalizes the air transport sector by allowing any company from each ECAA member state to fly between airports in ECAA member states, allowing a “foreign” airline to offer domestic flights. A similar system will be concluded with the Mediterranean partner countries in the field of air transport. The Euro-Mediterranean Air Services Agreement (EMAA) was signed on 12 December 2006 with the Kingdom of Morocco, on 15 December 2010 with the Kingdom of Jordan and on 10 June 2013 with Israel.  These EMAA agreements are in force.
