A while back Ryanair said they were focasing on EDI as they charges were low.
Brussels being droped as the route was increased from EDI
It's not a route which would be seasonal.
Gothenburg was on sale but as soon as EDI got the route it was dropped.
Paris BVA being reduced to 3 weekly was 7 last winter from PIK as EDI will now have 4 weely this winter.
Ryanair are withdrawing City routes from PIK and moving them across to EDI leaving PIK with the sun routes
Have you a source????
Last I herd Rome, Milan & Gothenburg were cities.
