Whenever I have gone to Dundee there have been substantial loads (got overbooked once, when the Air France staff at LCY all suddenly became non-English speaking until the manager had to come out).
It will be a shame to see Scot go after all these years. They are well into corporate charters (not a lot the size of the Do328 on the market) for companies, football teams, etc, but the closure of LCY from Saturday to Sunday lunch squelches much weekend demand for the, especially from sporting teams who the aircraft is an ideal size for.
The story abot LCY not liking sub-50 seaters was a few years ago, more passengers and less stand space then. In the last year or two they seem to have lost more operations than they have gained, so maybe a different attitude prevails now.
