Though if Scotland gets its way then tgsts going to be The UK's most Northely sirport. In which case id go fir expansion to take 737/A320 and try temo as much traffic from Edinburgh and Especially Glasgow. As there after battking the M8 uts nearly quicker to get to Carlisle.
So the SNP are planning to close all airports in Scotland after independence - WOW!
Being serious, I presume you mean England, in which case Newcastle is further north.
The airport is owned by Stobart who own Stobart Air, who fly for Aer Lingus and Flybe and who own Southend Airport. The only flights being proposed are to Dublin and Southend by Atr-42, which Stobarts own consultants say will need a subsidy of £250K.
Given this, and the lack of navigation aids and other facilities, any other flights seem unlikely (even a regional service to Walney Island!)
