The EIN-LHR flights of KLM (cityhopper) will be moved to LCY at the 31st of march. The slots at LHR will be used by NW.
However the twice daily(on weekdays) EIN-LCY flights won't be operated by KLM but by Cityjet. They will wetlease a D328 from Scot Airways for this flight and will fly it with their own metal (RJ85) after a few months.
