The airline which provides the Jersey to London Stansted service is pulling out of the island.
Other airlines are interested in the Stansted route, politicians say
Atlantic Express only took over the route earlier this year, but its parent company has been bought out and does not want to continue the service.
It is thought five locally-based cabin crew will be made redundant.
The politician responsible for Jersey Airport, Deputy Alan Maclean said several other airlines had expressed interest in the route.
The news comes a few months after Atlantic Express announced it would add another service.
Last week, the company said it was using larger aircraft over the Christmas period because of higher demand.
Flights will continue until 15 January. Anyone who has booked beyond that date will be given a full refund.
Deputy Maclean said he was confident Jersey would have a Stansted link in the future.
He said: "I would be hopeful that we could find another operator in the not too distant future, and I'm very optimistic that we will be adding more routes than we will be losing.
"There will be winners and losers, but what we have to ensure is that we work very closely with airlines to ensure we minimise the losses and increase the network that we have."
