The survey can also be found on the Aberdeen Airport webpage where they invite people to "Tell Us".
So go ahead and tell them, and see if they listen. We will wait and see. Note that in true Aberdeenshire style, only the opinions of local people, (i.e. those resident in Aberdeen City, Aberdeenshire, Moray, Angus, and the Shetland Isles) can take part in the survey. The opinions of other users, or potential users, of Aberdeen Airport do not seem to matter to BAA and Aberdeen Airport.
As a user of Aberdeen Airport on an almost weekly basis, I know how bad an airport it is. So if you can, go ahead and tell them.
