Interesting interview by CEO Jochen Schnadt with a German aviation industry website.
bmi regional will consider moving its AOC to the continent if that is required to keep operating under its "pan European strategy" as it is heavily reliant on non-UK routes (40 per cent of seat capacity - for comparison: Easyjet only 33 per cent).
Short-term concern is more about the future travel volume. The uncertainty and political instability, but particularly a lack of foreign direct investment in the UK could affect business travel - although this may be partially off-set for a certain period by additional travel resulting from the UK retrenching from the EU.
