FR have confirmed that cuts are a result of lack of airframes for 2014. They had load factors of 87% out of Magdeburg which is above the overall average (I now load factor is not a profit indication) but FR had no competion here and had a large catchment area. Maybe they'll go to Hanover or Kassel instead, if they get the deal they want.
Difficult one..
Route may be profitable but if can replace it with 4 sectors instead of 2 then can understand the reason but routes come and go all the time.
