A total of 284,456 passengers used Aberdeen International Airport in October, up 4.4% year on year.
The figures were the sixth consecutive month where both domestic and international fixed-wing traffic saw consecutive increases.
Helicopter passenger numbers, however, remained down year on year by 3.4%.
Managing director Carol Benzie said: “We experienced a good volume of passengers throughout October which was due to a healthy number of business and leisure travellers.
“Helicopter passenger numbers remained down year on year, however this decrease was very modest, showing a continuing stabilisation of the energy market in the region.
“This sixth consecutive monthly increase in total passenger numbers is highly encouraging and continues to demonstrate the demand for both our domestic and international routes.’
