Air Southwest had announced that it is to cease all operations by the end of September.
The airline will end all Newquay/Plymouth flights to Glasgow, Guernsey, Jersey and Manchester on September 14, while its remaining Newquay routes to Aberdeen, Bristol, Cork, Dublin and Leeds Bradford will finish on September 30.
Eastern Airways only acquired Air Southwest last autumn, but in a statement said that “forward bookings are significantly lower than required and the level of demand is not financially viable”.
It is a big blow to Newquay Airport and a dramatic fall for Air Southwest, which had been Newquay’s biggest carrier.
The airport’s MD Al Titterington said: “This decision is obviously disappointing for Newquay Cornwall Airport and the Cornish economy. The timing of this news is particularly difficult as airlines have already finalised their existing flight schedules.
“We are currently working with a number of alternative airlines to find replacement services and are confident that these will prove successful in the future, although it is inevitable that there will be a break in some services.”
Chris Ridgers, Cornwall Council cabinet member for economy and regeneration, added: “The decision by Air Southwest is disappointing but we will continue to work with other airlines to maintain a variety of destinations from Newquay Cornwall Airport.
“The airport has been very successful in developing a hub of aerospace industries at the commercial airport attracting international companies such as AgustaWestland which provide highly-paid, highly-skilled jobs for the local economy and we will continue to build on that success.”
