Looking at the proposed schedule, I wonder if Ryanair have got it wrong? I believe most of the potential pax would have been originating from the MST area for trips to London. However, with an 0655 departure for the return leg from STN, it's not going to have much appeal - unless they happen to be staying somewhere close to the airport. I don't see this route succeeding with the present timings, especially with KLM-Exel offering three flights a day for only just a few euros more.
