Ryanair has been granted a UK air operator certificate by the Civil Aviation Authority.

The Irish budget airline will now be able to operate UK to non-EU routes after Brexit, whatever the outcome.

Britain is set to leave the European Union on March 31. Ryanair has been calling for a transition deal to be agreed after the departure date, without which it fears disruption to flights in the spring and summer.

Ryanair’s chief legal and regulatory officer Juliusz Komorek said: “We welcome the Civil Aviation Authority’s decision to grant our UK based airline, Ryanair UK, with a UK AOC, allowing Ryanair to operate UK domestic routes and UK to non-EU routes in a post-Brexit environment.

“The risk of a ‘no deal’ Brexit in March is rising, and despite our robust post-Brexit structures, including our post-Brexit plan around European ownership, we continue to call for the UK and EU to agree a transition deal from 31 March 2019, so that any disruption to flights and British consumer summer holidays in 2019 can be avoided.”
