I used to use the direct Flybe LCY-BHD service but it was unusual to get more than about a dozen fellow passengers, which was surprising but must make VLM have little interest.
The -400 operator a couple of years ago was Lufthansa commuter operator Augsburg Airways, to Munich. That also didn't seem to get good enough loads and has been replaced by a smaller operation with a Dornier.
Regarding the trials done at Woodford, does anyone use the facilities at Gloucestershire nowadays (runway markings of LCY dimensions and PAPIs set to the LCY angle), which I believed were specially provided for LCY training.
