VLM LCY-IOM
I used that service around 10 times, the last occasion being in 2008 which must have been around the time it finished. It was great; full service, very punctual, newly refurbished (at the time) aircraft and very good fares. But it had very little publicity and, although it is long time ago, my recollection is of LF's around 40%-50%.
Besides the Monday to Friday day-stopper, which used to arrive in IOM around 10.15am and leave at around 5.00pm, there was a Sunday evening rotation from LCY at around 5.00pm, getting back there at around 8.00pm.
There was also through ticketing to the wider VLM network.
