Don’t think there is any doubt that the city itself is on the up, but that’s not driving demand for air travel here just yet. You only have to look at the lack of replacements on the Frankfurt route to see that.
Will be interesting to to see what effect the bypass has. The traffic situation in Dundee might drive the affluent eastern suburbs and Angus travellers up to Aberdeen. TBH it’s an attractive option if you take the car, but daft as it may sound driving north to travel south is always difficult to get people’s head round regardless of how attractive it is.
Problem will be the default action of greed surrounding anything to do with ABZ. Parking will go up, fares will go up. Years of cashing in is difficult to let go of.
