Wasn't there a plan by the WA to do a PSO on Hawarden to serve North Wales like they do with Anglesey? I know Chester is in England but it is the closest airport.
But Harwadden CEG is actually in Wales (Flintshire).
I don't see much time gain in an air service from anywhere other than LGW, avoiding the time consuming London transit.
Wouldn't be LGW: its management no longer wants small aircraft and will price them out, as shown by the demise of BE at LGW.
