MANFOD,
I think it's been established that Ryanair will be at least 1 extra based for the whole of summer 16. The programme looks about done, so, unlikely we will see 2 extra based. Brindisi and Malta will be run by aircraft from those bases, Bratislava will be run off a Manchester based aircraft.
Due to the large scale expansion of Spanish services , and the 3 new routes, unless we see any more new away based routes, I think the S16 programme for Ryanair is about done.
