Easyjet to seek a new UK AOC pre Brexit and also embark on heavy promotion of investing in Easyjet to non-UK shareholders in the EU.
Counting Stelios as a Cypriot, over 50 % of Easyjet shares will be held by EU citizens post Brexit. Easyjet could then move its registered office outside the UK and become a (eg Austrian) company solving the problem of Brexit
I imagine that some head office staff might need to relocate on a permanent basis to Vienna. This might perhaps explain why Easyjet don't seem particularly focussed on finding new office space in Luton at the moment
