The operators of Dundee Airport say they believe Flybe may be convinced to resume flights to Amsterdam.
The airline said it is suspending the flights, citing a lack of suitable radar cover for large aircraft as one of the main reasons behind the decision.
Officials refused to say why the route was able to launch in May if radar coverage was an issue, or if it had become an issue since flights were initially suspended in November.
Dundee Airport is owned by Dundee City Council but operated on its behalf by Highlands and Islands Airport Limited.
A spokesman for HIAL said they were “encouraged” that Flybe had only decided to suspend the service, rather than terminate it completely.
He said: “We have been working with the Flybe team for a number of weeks to try and resolve the operation issues the company has had around the Dundee to Amsterdam service and felt we were making good progress in terms of delivering a solution which worked well for all concerned.
“We are nevertheless encouraged by the fact that Flybe see this as a suspension rather than a termination of the flight, with the aim to restart the service in the future.
“The Dundee Airport team will continue to work to resolve the new requirements they have around enhanced radar coverage and will present those to the senior Flybe team in due course.
“The announcement has no impact on the day-to-day operations at the airport.”
Customers expressed their scepticism over the decision to halt the service.
Dundee-based businessman Chris van der Kuyl posted online: “This is absolute nonsense. Total obfuscation by Flybe.
“If there was a problem with light aircraft and radar then neither CityJet nor Logainair would have been flying daily to London for over 10 years.
“Let’s encourage Loganair or someone equally entrepreneurial to take on the route.”
