Ryanair base?
I think we can all dream on. Although DTV does indeed fit the Ryanair profile, they do seem to have been going for the larger airports of late (EDI, BHX and BRS). This would suggest that NCL would be the more likely base. But I think before either airport gets too excited, look at the evidence or recent route closures and you can conclude that the North East is well down the list of Ryanair priorities.
