Daily services to Manchester and onwards to Aberdeen, together with non-stop flights to Edinburgh and Newcastle, will be suspended between November 2022 and March 2023.
In a further blow to Cornwall’s connectivity, summer routes linking Newquay with Teesside and onwards to Inverness will not return in 2023, and planned growth on other routes is to be redirected to other UK airports.
A spokesperson for Loganair said: “It’s with a heavy heart that we’ve taken the decision to withdraw our entire winter Newquay programme and to curtail our Summer 2023 plans too.
"Despite all of the challenges that the pandemic has delivered, we’ve worked incredibly hard over the last two years to build up our presence at Cornwall Airport Newquay.
"We’re most disappointed that short-sighted and short-term decisions by the airport’s management to incentivise unsustainable operations by other airlines leave no prospect of winter flights remaining viable, particularly against a backdrop of high fuel prices and rising inflation."
Loganair has contacted all customers with forward winter bookings on the affected routes to offer a change of travel date or refund options.
