Irish budget carrier Ryanair is to drop its Aberdeen-Dublin route after failing to agree financial terms with Aberdeen Airport operator BAA.
Existing financial arrangements to operate the route are not being renewed and, as a result, the carrier has decided to end the service.
In a statement it said it regretted that "the high-cost BAA monopoly at Aberdeen has refused to extend this low-cost deal, or match the competitive cost agreements available to Ryanair at many other UK and European airports". It described the end of the service as a "forced closure".
Ryanair's final Aberdeen-Dublin flight will depart on 28 October. Anyone booked on the route after that date will receive a refund, said the carrier.
A BAA Aberdeen spokeswoman said that it was difficult to put a finger on precisely which aspect of the financial arrangements Ryanair had objected to as it had re-negotiated different deals over the years. Aberdeen had been holding discussions with the carrier over opening more leisure routes from the Scottish city when the impasse over costs was reached.
"It's important to note that we're not losing the Dublin route," she added. "Other carriers operate it."
Innovata schedules show that Aer Arann operates Aberdeen-Dublin, under the Aer Lingus Regional banner.
