The grants will be allocated to Donegal, Knock, Kerry and Waterford airports
The Transport Minister has announced €2.7 million in grants for four regional airports around the country.
Donegal, Ireland West Airport Knock (IWAK), Kerry and Waterford are in line for the extra funding.
IWAK will receive the largest grant, with more than €1.3m allocated.
Waterford Airport is in line for €870,000 in grants. However, that allocation will only be confirmed when scheduled passenger services resume at the airport - none are currently operating.
The Department of Transport says airport authorities in Waterford "are in discussions with a number of airlines with a view to securing a replacement carrier for VLM Airlines which filed for bankruptcy protection in Belgium in June".
Donegal Airport has been allocated €341,000, while Kerry Airport will receive a grant of €205,000.
Minister Shane Ross said: "The funding support that I am announcing today will assist with capital investment on various projects at the four regional airports over the coming months in the areas of safety and security such as CCTV monitoring equipment, repairs to taxiways, aprons and perimeter roads, upgrades to electrical systems and winter-ready equipment.”
Today's announcement follows €1.2 million worth of grants for regional airports that were announced in April.
The Programme for Government included a pledge for an "additional €10 million to intensify efforts to properly prepare our regional airports for a future where they can operate on a standalone commercial basis".
