From the Luxair website:
Saarbrucken – Luxembourg – London-City
Starting September 2008, Luxair will connect Saarbrucken with the business airport of London-City. Services to London-City will be operated from Monday to Friday in the morning and evening as well as on Sunday evenings. These flights will depart Saarbrucken via Luxembourg.
Nothing terribly exiting as it is only an extension of the LUX route, but nevertheless
Maybe a move to fill the much larger Q400 in the light of heavy competition by VLM on the LUX.
Also in the City Star thread continuing rumours about an announcement of ABZ-LCY.
