If it was just the economy being the problem then all the regional airports would be in the same situation as DSA.This is not the case,the northern regional airports with large catchment areas are continuing to expand.The likes of Leeds,Manchester and Newcastle are seeing new airlines and more routes being introduced.You have said in your above post the airlines will go where the money is.The concern for DSA is similar to MME once an airline reduces its frequencies or stops flying altogether will they return even if the economy improves?
