I received an email from Flybe several weeks ago stating that they had "no further plans" for routes from SEN, which doesn't sound too hopeful, although I suppose it could mean no definite plans as yet.
The 'Evening Echo' also reports that the planning application for the proposed station Parkway has been withdrawn due to local opposition and that a revised planning application is being drawn up in that regard.
Neither of the above are likely to lead to an early start on building the new terminal I fear.
