Bydgoszcz is cut due to a dispute between Ryanair and the airport. Many Ryanair routes from the Polish city are being cut. Glasgow is picking up Brussels as a replacement so no cut in capacity.
STN is cut by 7 departures a week, I believe, not 10. But again this is part of much wider cuts to the STN network. EDI will see similar scale cut backs.
Ryanair will launch Alicante, Malaga, Gran Canaria, Lanzarote and Sofia this winter from GLA so despite the cut to STN, still a substantial overall increase. Plus Wizz Air will have more flights to EE this winter compared to last.
