I've got lost with this now but having just looked I can tell that other than the Mon, Wed and Fri services to/from Skavsta which do a W pattern to Beauvais in between, there is currently no sign of any W patterns at Modlin.
It would seem there is potentially a based aircraft that goes to Gdansk and back with a 50 minute turnaround at Modlin before going to Wroclaw. In which case I imagine there would be many new routes to come.
Alternatively there might be a new route or just a change in the schedules from another base which arrives in Modlin say around 11:45 and does the Gdansk and Wroclaw services before returning to it's base at say 17:45. That would be like a "double W pattern" so to speak so kind of doubt that will happen.
I guess we'll just have to wait and see.
