Aberdeen airport has several places where you can get a meal, a snack or just a drink.
Before security there's The Kitchen, which offers a wide range of sandwiches, plus some hot dishes, and branches of Wetherspoon's and Costa Coffee.
After security there's The Globe, which serves pub food, and another branch of Costa Coffee. You'll also be able to grab snacks in WHSmith and Boots.
All the food outlets are open by 6am and stay open into the evening, though The Kitchen and Costa Coffee close at 4pm and 5pm respectively on Saturdays.
