Good question David - not sure of the answer though!
The more connections the better and good luck to Eastern (ASW) on this one.
Living south west of Newquay if I wanted to go to ABZ I would probably just drive to EXT which except when the grockles block the roads up would take about an hour longer and in the long run would still be quicker, more comfortable and cheaper.
If I lived in Newquay I make take a different view though. Anyway good luck and hope it increases numbers.
