The European Common Aviation Area (ECAA) is a single market in aviation services. ECAA agreements were signed on 5 May 2006 in Salzburg, Austria between the EU and some external countries. It built upon the EU's acquis communautaire and the European Economic Area. The ECAA liberalises the air transport industry by allowing any company from any ECAA member state to fly between any ECAA member states airports, thereby allowing a "foreign" airline to provide domestic flights.

[Member countries of the ECAA are shown in dark and medium shades.

Brexit

Because the UK has left the European Union (Brexit), the UK is no longer part of the Common Aviation Area. Unless permission or new treaties with the UK are made, aviation to and from the UK may stop. There was a delay in this hard Brexit until the end of 2020, because the Brexit withdrawal agreement states that most EU rules continue to be valid for the UK during 2020. However, EU has approved regulations 2019/494 and 2019/505 in order to secure air traffic between UK and EU plus EEA. Also, the British government has taken various steps to ensure the continuation of air travel, such as an open skies agreement with the United States. The British airline EasyJet which has many flights outside the UK has set up a subsidiary in Austria (easyJet Europe) whilst keeping its headquarters in Luton, England.
