If PIK did exit passenger ops, where would Ryanair stand in terms of its maintenance base/ hangar???
As long as the airport stays open I doubt anything would change. Last winter they had almost daily positioning flights to and from GLA which I presume were for the purpose of bringing aircraft for maintenance. So effectively passenger ops weren't providing the entire source of aircraft for the hangar. Crew for test and positioning flights would be the only thing lost, but they're just a short taxi ride away from GLA if needed anyway.
