Hope they are doing well in FDH, but cannot understand why it is just possible to book the tickets from 11th January.
If they get the same load factor like Intersky it wouldn't be that bad:
Average load factors last 12 months:
Düsseldorf 28 PAX (56%)
Hamburg 37 PAX (74%)
Berlin 40 PAX (80%)
Due to the reason that Intersky return flights cost at least 198€ and VLM return flights start with 159€ it may possible that they get the same or also a better load factor. The first weeks will be difficult I guess because ticket selling just starts 4 weeks before the flights are starting. We'll see.
