If you could fly people from Connel to GLA for between 50 and 70 quid I reckon you would be on to a winner, otherwise the locals would drive, I know I don`t think anything of driving 2hours to Glasgow, but if I could get a flight for not loads more than the cost of the fuel, I would fly. As no sig mentioned its worth considering your average west highlander`s mentality here. (Also worth noting that all other froms of public transport take 3 hours to get to Glasgow)
Just a locals tuppence worth.........
