Loganair is raising capacity between Aberdeen and Dublin this winter as it marked the first anniversary of flying the route.
The regional airline helped re-establish the link between the two cities following the collapse of Stobart Air a year ago.
The number of seats offered is to be increased with lower fares on the route which is operated up to six times a week.
Lead-in fares from October 31 will be cut by about 18% to £59.99 including all taxes, fees and charges.
Loganair is projecting to offer almost 50,000 seats on the route in the year ahead, almost twice as many as in its first 12 months
The largest aircraft in its fleet, a 72-seat ATR-72, has now been deployed due to the popularity of the service between the north of Scotland and the Irish capital.
Loganair’s operation at Aberdeen now supports more than 100 direct jobs for pilots, cabin crew and engineers and a further 100 through ground handling companies and the airport’s wider supply chain.
Chief commercial officer Luke Lovegrove said: “It’s great to celebrate our first anniversary on the Aberdeen-Dublin route by setting out exciting plans to offer more seats and lower fares on this important route.
“It reflects just how far we’ve progressed since we tentatively began flights last September – and it’s all too easy to forget that this was a time when pandemic restrictions still dominated the travel industry.
“With those firmly behind us, we’re pleased to be looking to the future and providing more of the services that our customers need, whether they be travelling for business, leisure or to catch another flight on one of Loganair’s wide range of partner airlines.”
Tourism Ireland brand partnership manager Cormac O Suilleabhain added: “We recognise the vital importance of direct air connectivity and the key role that this air link to Dublin provides for Scottish holiday-makers.
“We look forward to welcoming visitors from Aberdeen to the island of Ireland and working with Loganair to promote the route and further expand their network to the island.”
