Frequency is being raised by KLM between Aberdeen and Amsterdam this summer.
A fifth daily flight has been added to the Dutch airline’s schedule on the route to its Schiphol airport hub.
The additional frequency will run in May, June, September and October, raising capacity by 10% with 20,000 additional seats.
The extra service will be operated by a 100-seat Embraer 190 regional jet.
The new flight is scheduled on weekdays between May 6 and July 5 and September 2 to October 25 with connections to 165 destinations worldwide.
Aberdeen airport managing director Steve Szalay said: “We warmly welcome KLM’s decision to expand its presence here at the airport.
“With more than an additional 20,000 seats available for passengers to purchase, this is a real shot in the arm for us as we enter an exciting period, as our terminal transformation project is on course for completion in the autumn.”
Air France-KLM UK and Ireland general manager Benedicte Duval added: “The extra frequency will not only allow more local people take advantage of KLM’s worldwide network through Amsterdam Schiphol airport, it will also provide more choice and convenience for inbound travel to Europe’s energy capital, boosting local business.”
