Well, JP almost stoped their flights last year due to financial circumstances. They got some financial aids from the goverment, still they are forced to cancel and rescheduale their flights.
All the information regarding timings from your last post are correct. I would't even think about 35 min. transfer in FRA - you will not make it. The MCT in FRA is 45 min. so noone will but such a flight into your reservation, althouh it's not a problem to accomodate pax on other JP flights as JP flights are ussualy not full. But MCT still has to be observed anyway.
Have a good trip and rgds from Slovenia!
