Irish carrier Aer Lingus is to operate a total of six flights per day during the winter season, increasing competition with low-cost rival Ryanair on the route.
Aer Lingus offered four daily flights between Gatwick and Dublin last winter, and currently flies five-times-daily.
From October 30 a new 1750 departure will be added from Gatwick, along with a 1950 departure from Dublin.
A new 1255 departure from Gatwick has also been scheduled to “bridge the gap between the existing 1050 and 1450 flights”.
Aer Lingus says the move means it will offer more frequency on the Gatwick-Dublin route “than any other airline”, referring specifically to Ryanair which also operates routes between the two airports.
Aer Lingus also flies between London Heathrow and Dublin, while Ryanair offers additional services from Luton and Stansted. Bmi flies to the Irish capital from Heathrow, and Cityjet operates from London City.
