Islanders and visitors can win tickets for the new helicopter between Penzance and Scilly in exchange for sharing their views on how it will operate.
The team behind the new helicopter route has launched a survey to "ensure it provides the best possible service for the islands" when it launches in spring 2020.
In return for their views on issues such as schedules, services and future plans, residents and visitors can enter a prize draw to win one of three pairs of tickets for the new service.
The survey, which will remain open until May 31st, can be accessed at www.penzanceheliport.co.uk/survey.
Helicopters will operate from a new Penzance Heliport to the islands of Tresco and St Mary's under an agreement between Penzance Heliport Ltd and experienced operator Sloane Helicopters.
The first turf for the heliport was cut in March and building work is now well under way at Jelbert Way, adjacent to the previous heliport site. Tickets for the new service go on sale this summer.
Tom Matthews from Penzance Heliport Ltd said: "We're now less than 12 months away from the launch of the service, with tickets going on sale this summer.
"Everyone has waited a long time for a new helicopter link between Penzance and Scilly, so we've launched this survey to ensure we're listening to visitors and islanders so we provide the service they need and want."
The new Isles of Scilly helicopter service will take to the skies in spring 2020, with flights from Penzance aboard the AW139 helicopter arriving on Tresco or St Mary's in 15 minutes.
Penzance Heliport has been awarded £1.8 million of European Regional Development Funding to support the development of a multi-modal hub connecting Penzance, Tresco and St Mary's.
Tickets will go on sale from summer 2019 at www.penzanceheliport.co.uk.
