Classic Route Wind-down
Introduce inferior timings to annoy your core business travellers.
Change the previous modern and fast aircraft to something old and slow.
Build scheduling around the aircraft and crews and NOT the market.
When passenger numbers fall blame a contracting market and walk away claiming you've tried your best! How many times have we seen this?
To be honest I doubt CityJet exepct it to work wtihout the Dornier228's speed and convenience so they'll try it over the winter and probably see the Fokker 50s re-deployed onto other routes come March I suspect.
