Unfortunately for the EU, the ball is worth around 40 billion euros, and is presently on our side of the court. The EU has quietly made 'cherry picking' exceptions before when it suited Commission politics, but is playing hard-ball at present to discourage anyone else from daring to leave. Do they expect UK to recognise EASA licences after Brexit and KLM be allowed to land at LHR when EASA licences issued the day before to UK operators do not allow BA to land at AMS? Wait and see.
