I don't think that ASW would be interested. It has never appeared to be a very happy relationship in the past.
With the loads that Eastern seem to have out of BRS I would have thought that perhaps a transit stop to include EXT could work for some destinations, or pehaps someone like Jet 2 or BMI Baby. If MME can work for Summer to NQY there must be some interest to EXT with the 'business' use alone?
It has always surprised me that nothing has been done to Alderney? I would have thought that it had a similar draw / market as the Isles of Scilly?
