Maybe the honeymoon of LS at BLK is coming to an end, and the airport is now feeling the rath of poor support from the public.
Looking at the February results, the flights had mid 60% load factors. For a first summer season, this isn't bad for AMS and PRG when most holiday makers are looking at Spain, Portugal etc. I'm confident they will be back for the winter season though, after all, they must have had good enough loads last winter for them to carry on!
Lets hope for new routes at all the bases, and maybe some spanish routes will carry on through this winter, unlike last!
