Aer Arann is to add a second flight on its Waterford-Luton route from 7 June with fares to start at €29.99 each way plus taxes and charges.
The additional daily service will leave London Luton at 5.30pm and depart Waterford at 7.25pm.
Aer Arann expects to carry an extra 24,000 leisure and business passengers on the route during the first year of providing the second flight.
Announcing details of the extra flights, commercial manager Jennifer Mooney said the airline was delighted to be introducing the additional service.
The airline has carried over 20,000 passengers out of Waterford since introducing the service last summer and has a current load factor of almost 80% on its daily flights.
Aer Arann will begin a Waterford-Manchester service on 4 May.
