With the UK’s departure from membership of the EU on 31 January 2020, aviation has been recognised as one of the sectors affected by Brexit. The potential disruption of Brexit for air travel has made it clear that air transport needs to be at the forefront of the negotiations of the new UK-EU27 relationship. Since the Brexit vote, ACI EUROPE has closely engaged with the European Commission’s Task Force for Relations with the UK and the UK government to call for aviation to be prioritised. ACI EUROPE has underlined the impact of Brexit on European air transport, connectivity and the wider economy. It has also repeatedly stressed the need to keep the most liberal aviation regime between the UK and the EU to safeguard air connectivity, thus preserving the interests of consumers, airport communities and aviation stakeholders.
