I don't think that Ryanair will launch a German route as Ryanair are not happy with the German travel tax.
EDI operates from GWY so if Ryanair were to do the route it would only be twice or three weekly. It is been dropped from SNN and its not the type of route to go seasonal.
AGP will more than lightly stay at SNN next summer as Ryanair have to meet a set amount of passengers and people from Limerick city would not travel to Knock. They would go by Cork Airport. Knock may get it as well but I wouldn't think so. When GWY had AGP they didn't do that well. A lot more people traveled from Waterford on therm. Aer Arann and considering resuming AGP. FAO and mabye Palma. Not sure if they will go from GWY but when all routes went from Waterford they did a lot better than GWY. So I don't think GWY will get them.
