Kerry airport is to cut its workforce by almost a third.
Management said it was necessary to cut 20 jobs - from a staff of 65 - to safeguard the regional hub’s future.
Denis Cregan, chairman of Kerry airport, blamed a fall-off in passenger numbers and Ryanair’s decision to reduce services to Dublin.
“This action is necessary to safeguard the business in the medium term and to protect the remaining jobs," he said.
“We regret the necessity for such action but it is considered unavoidable in the present circumstances.”
Ryanair cut the frequency of its daily return flights between Kerry and Dublin from three to one in October.
The airline claimed it was forced into the move because the Government did not increase public service obligation subsidies on the route.
Kerry airport said the proposed lay-offs will take effect from February 4th. Staff representatives are in talks with management.
Separately, Ryanair will resume a twice-weekly service from Kerry to popular sun destinations Faro in Portugal and Alicante in Spain from March.
At Shannon airport, Aer Lingus has announced a new daily route to London Gatwick.
The service begins on March 27th. Flights will depart Gatwick at 6.50am, arriving in Shannon at 8.15am, with the return leg departing Shannon at 9am, to arrive in London at 10.25am.
