It was revealed that Skybus, the airline of the Isles of Scilly Steamship Group, will operate the route following the demise of Eastern Airways.
Eastern had operated the Cornwall Airport Newquay to London Gatwick route since 2021.
The airline suspended all operations at the end of October.
Skybus will resume the service starting 23 November and tickets are now on sale.
Cornwall Council awarded Skybus the Public Service Obligation (PSO) contract.
Initially, it will fly once daily and then ramp up to twice-daily service on weekdays from February 14, 2026.
Skybus will deploy a 70-seat ATR72 aircraft regional turboprop aircraft on the route.
“We are thrilled to launch this new service. It is not just about making travel easier for passengers; it’s about creating opportunities – for businesses, for tourism and for the local communities we serve,” Jonathan Hinkles, managing director of Skybus, said.
“As a Cornish company with more than 40 years of aviation experience, we understand how critical dependable air links are for our region.”
