Not a good move by Jet2 there. PRG passenger figures have been contracting this year (everyone's already been there).
I hope we're not about to see another situation like BCN a couple of years ago, where too much capacity will lead to OK WW pulling out.
It's unfortunate to see LS chasing after the same old destinations. Similar to the problem down at BHX, where incumbent airlines are often accused of failing to find new and interesting places to fly their planes.
