Ryanair is to cut its Shannon airport flights by a fifth, it has been announced.
Chief executive Michael O`Leary confirmed the scaling back of services this winter because of increased passenger fees.
The Paris route will be closed, with some London Gatwick and London Stansted services also cut.
Mr O'Leary said: "It is clear that the Irish Government and the Dublin Airport Authority monopoly are determined to destroy Irish air traffic, Irish tourism and Irish jobs."
The budget airline said traffic at the Co Clare centre had collapsed since last year and blamed high costs for the decision.
The chief executive criticised the 10 euro Government-imposed air travel tax and said traffic at Shannon had fallen by more than a million passengers since last year.
The airport announced on August 28 this year it was increasing charges by 1 euro 58 cents per passenger and said this was in line with other regional airports. It was the first rise since 2004 and the airport director said it was introduced because Shannon was losing money.
Mr O`Leary said: "Irish air traffic and tourism can return to growth and prosperity but only if there is a return to a low cost access policy."
He called for scrapping the tax and reversing the airport authorities' cost increase over the last two years.
Ryanair is pulling out of Belfast City Airport from October 31. The airline said the decision followed the airport's confirmation that a public inquiry into a planned runway extension would be further delayed.
