Air Berlin
Dont think STN will be in there plans.
Easyjet have 5 flights a day to STN if AB were to go on the route they would only have 2 flights aday. Some of EZY flights are only half full and i dont think that AB would be able to get the right slots at STN.
The routes which Air Berlin will do from NCL will be SXF,CGN,MUC
I could be wrong but these are the mot likely.
They have a codeshare with HLX so they may even take over the hannover
