With Ireland being a modestly sized island with an extensive and speedy train network and modern motorways connecting the main cities, there’s little need for too many internal flights. The only internal flights on the island of Ireland are the Dublin-Kerry and Dublin-Donegal routes, which take approximately 40 minutes.
Flights to all three of the Aran Islands are with Aer Arann. These flights to the islands leave from the picturesque setting of Connemara Regional Airport with a journey time of approximately eight minutes. There are no flights between the islands themselves.
Galway Airport is now closed for passenger traffic and Sligo airport has no scheduled services.
There are 10 airports offering international flights on the island of Ireland:
Belfast International Airport
Belfast City (George Best) Airport
City of Derry Airport
Ireland West Airport Knock
Visitors to Ireland will need their passport at all times when travelling internally on the island of Ireland.
