The number of passengers passing through the north east port rose by 10.2 per cent to 275,700 in March compared to the same month last year, according to new figures.
Passenger numbers at Glasgow Airport reached 507,600 - up 4.6 per cent on the same month last year - while Edinburgh numbers fell by 2.8 per cent to 700,000.
Aberdeen Airport managing director Derek Provan said: “The continued growth in passenger numbers is good news for the airport and reflects the obvious buoyancy in the regional economy.
“With the summer schedule now under way, we are confident that this success story will continue.”
Glasgow Airport said international traffic growth had boosted passenger numbers, while Edinburgh blamed the reduction in Ryanair’s winter schedule for the fall.
