Airline Flybe has said it has not received any public money for the Dundee to Amsterdam air route since direct flights from the City of Discovery were stopped.
Passengers are currently bussed to and from Edinburgh Airport if they have booked a seat on a flight.
Although the UK Government has said funding “remains on the table”, the airline said it has not received any money since its review of operations began.
A spokeswoman for Flybe said: “Flybe can confirm that since it has been operating its Dundee to Amsterdam service via Edinburgh, due to the ongoing review of its operation at Dundee Airport, it has not been in receipt of any funding from the Government’s Regional Air Connectivity Fund.
West End councillor Richard McCready has questioned where the money was going now flights are not operating out of Dundee.
But he said he hopes the flights can be returned to Dundee Airport as soon as possible.
He said: “I want Dundee to be as well-connected as it can be and that includes the flights to Amsterdam which, in terms of people using them, have been a huge success.
“It’s frustrating that it is not currently operating out of Dundee.
“Although the airport is operated by Highlands and Islands Airports, it is still owned by the council and I want to know what we can do to make it work.”
Flights to and from Amsterdam were introduced in May and proved an immediate success.
Although they initially only operated five days a week, it was soon extended to a six and then a seven-day-a-week service.
But passengers have been bussed to and from Edinburgh since October after direct flights were stopped.
Flybe has blamed “operational reasons” for the need to take passengers to Edinburgh but has so far refused to divulge what they are.
Although Flybe continues to take bookings for the flight, it has said passengers will continue to be taken to Edinburgh until January.
