I am from Aberdeen but usually fly from GLA where I live. I was up a few weeks ago and was checked in by the most disinterested guy in the world who turned around to me and said 'oh, you're on a business class ticket did you know?' there's actually a lounge here you can go into. Follow the signs.' That was it. I 'actually' thought the lounge was great, but it was a Monday and very empty, super polite staff, great view and a bottle of BrewDog IPA, perfect for a quick half hour visit.
