Ireland covers a relatively small geographical area and has just five domestic air routes on offer at present. Two of these connect Dublin Airport (DUB) with Donegal Airport (CFN) in the northwest and Kerry Airport (KIR) in the Southwest. The other three routes connect each of the largest three Aran Islands - Inishmore (IOR), Inishmaan (IIA) and Inisheer (INQ) - to Connemara Airport (NNR) on the mainland near Galway city.
