MAN could start doing something to the booking engine they have on their website. For a specific Friday in August I know both Norwegian and SAS fly to MAN, MAN-SVG does not give any result all. On the airlines websites, DY has one direct flight, SAS has 8 one stop options, BA has 7 one stop options, KLM/Air France has one stop 12 options and Luthansa has 6 one stop options.
