BBCThe Civil Aviation Authority said all of Eastern Airways’ flights had been cancelled, including services from Newquay to London Gatwick.
Tim Dwelly, Cornwall Council cabinet member for economic regeneration and investment, said the airline’s collapse was “very, very disappointing”.
He said the council was doing all it could to get a decent carrier on board to take over the Newquay to London route.
“There’s going to be weeks of disruption for people who had booked flights and we’ve got to put them first,” Dwelly said.
“But we are on it in a big way and we’re lining up a a temporary solution, which should be announced hopefully this week; but it will still take a while before it starts.
“But I want everyone to know we’re doing everything we possibly can.”
North Cornwall MP Ben Maguire, whose constituency includes Cornwall Airport Newquay, said the route was relied upon by residents, businesses and the tourist industry.
“The PSO route from Newquay to London is vital for Cornwall’s local economy and I have already spoken to senior figures at Cornwall Council to urge them to safeguard it in light of this news,” the Liberal Democrat added.
Cornwall Chamber of Commerce’s chief executive John Brown said the route was important for a lot of people and the authorities needed to “jump into action”.
“A decent carrier offering a really consistent, great service to London will invariably see passengers book on,” Mr Brown said.
