Ryanair is to stop operating its Dublin to Kerry and Dublin to Cork routes.

The Dublin to Kerry route will cease from September 7, although the airline said it will operate its 'All-Ireland' flights on September 17, 18 and 19.

Flights on the Dublin to Cork route will stop from October 30.

The airline said it was halting the routes due to a number of factors including fewer passengers on the Cork service due to improved motorway access, a new PSO subsidised operation on the Dublin to Kerry route and what it called 'excessive' DAA charges at both Dublin and Cork airports.

The airline said it regretted the decision and added that passengers who have booked to travel on these routes after their closure will receive a full refund.

Cork Airport said today that it is disappointed but not surprised by Ryanair's decision to pull the Cork-Dublin route by the end of October.

It pointed out that passenger and landing charges at Cork Airport have not increased since 2004. It also said it has invested in co-operative advertising and marketing support with Ryanair in an effort to stimulate more demand for this route.

'Cork Airport is aware that the Cork-Dublin route is a strategic link for the greater Cork region and will continue its endeavours to deliver a more appropriate, long-term sustainable solution to air connectivity between the two cities,' it said in a statement.
