I had understood from an article in the Independent that unanimity was required for voting on issues such as this, but reading the following opinion (in favour of O/S, as it happens), I'm not quite sure:

The writer suggests that the UK cannot block this on its own (suggesting Qualified Majority Voting). If true, this would be great, BUT what is the actual position? From what I have read, I'm unfortunately of the view that unanimity will be required, in that one of the several areas which requires unanimity is treaty agreements.
With regard to the points at issue, such as cabotage within the US, this has never been on the table, but more to the point, it is somewhat academic, because I simply cannot see EU airlines availing of it, even if it were available.
