Flybe is to drop its flights between Gatwick and Aberdeen on October 28.
The carrier currently offers a three times-daily service between the two airports, using Embraer aircraft.
“Flybe carefully reviews the viability of all our 180 plus routes on a regular basis looking not only at passenger numbers but also at external cost pressures,” said the company in a statement.
“This is done not only to monitor where we can offer increased regularity on a given route but also where passenger numbers make a flight environmentally, as well as economically, harder to justify.
“Unfortunately, after much consideration Flybe can confirm it is cancelling its Aberdeen to Gatwick route from the end of the IATA summer season on Sunday October 28.”
The move will leave just Easyjet serving the Granite City from Gatwick. BA flies to Aberdeen from Heathrow and London City, while Easyjet also serves the city from Luton.
