Ryanair boss Michael O’Leary: Hard landing for UK flights

He said Ryanair will have to make plans to move all its planes out of the UK as early as the end of 2018, if the UK fails to stay in the current Open Skies agreement.
The disruption to British flights will be severe from March 2019 because unlike other industries, aviation is not governed by World Trade Organisation rules and that the EU will insist that the UK sticks to some form of Open Skies agreement, he said.
