The airport’s operating profit rose €12,085 to €30,980, despite turnover falling 5% from €6m to €5.8m due to a fall in fuel sales.
Commenting on the airport’s financial results, Kerry Airport chairman Denis Cregan said: “The year 2015 showed a welcome return to positive passenger growth with of 4% increase year on year.
“We continue to explore and pursue new destinations, and new airlines, as well as holding discussions to increase frequencies to our existing destination with our current carriers.
“We have intensified our activities in this area recently but we expect results will have a long lead-in time.”
The Farranfore airport has regular connections to Germany’s Frankfurt-Hahn, London-Stansted, and London-Luton airports, as well as summer connections to Alicante in Spain and Faro in Portugal. All are operated by Ryanair.
The subsidised daily connection between Kerry and Dublin, which is in place until 2018 and operated by Aer Lingus Regional, saw passenger numbers rise 20%.
The load factor on the route rose significantly from 56% to 67% but remains some way behind the route’s 75% target.
Mr Cregan warned that passenger numbers on the route would have to increase.
Airport management was approaching the carrier to increase flight frequency to offer an improved service.
The Kerry-Dublin flight ‘interlines’ with Aer Lingus and Etihad Airways services, meaning baggage can be booked straight through to and from nine US cities, as well as cities in Australia, and the Middle East.
Passenger numbers on the airport’s London-Stansted and London-Luton routes also increased last year.
The twice-weekly German route is reaching its maximum capacity and the airport is looking at putting on extra flights on the route.
New destinations, as well as new airlines, were being pursued Mr Creegan said.
Some €505,000 was spent during the year on upgraded security facilities and fire safety equipment, with the support of funding from the Department of Transport, Tourism and Sport.
The Government operating grant allocated to the airport in 2015 under Regional Airport’s Programme 2015-2019 was €311,000, down from €507,000 the previous year.
Kerry Airport’s AGM is on June 22 at the Earl of Desmond Hotel, Tralee.
