Flybe has cancelled its planned winter schedule from Isle of Man.
On its website, the airline blames delays with aircraft deliveries.
Last September Flybe announced it would operate five flights a week between the Isle of Man and London Heathrow and six to and from Belfast City.
The "enhnaced service" service was due to begin this weekend.
A spokesman said: "Flybe deeply regrets the inconvenience that will be caused to passengers affected by this decision.
"The airline will provide full refunds, as well as applicable compensation, to all those impacted by these unexpected cancellations.
"Passengers can claim refunds by following the link provided in their cancellation email".
More information about refunds can be found here.
