Flybe’s Aberdeen-London City service will be operated by franchise partner Eastern Airways from May 7.
The continuation of the route will result in the same weekday frequency of two flights a day in each direction and also a Sunday service, with all flights bookable at flybe.com.
In the long-term, the route will be operated by a 76-seat Embraer 170 jet, but will initially start with a 50-seat Saab 2000 aircraft.
The fast jet connection will offer quicker flight times of one hour 15 minutes between Aberdeen and London.
Carol Benzie, Aberdeen Airport managing director, said: “A seamless transition from Flybe to Eastern Airways, with no break in the service, and a slightly shorter journey duration will hopefully be welcomed by regular travellers on this route. Good connectivity into the heart of the UK’s capital is vital for our passengers as well as for the economic prospects of the larger north-east region.”
