Frequently asked questions about domestic flights in Ireland

Does Ireland have any domestic flights?

Yes, but the domestic network is very small. The main routes connect Dublin with Kerry, Donegal and (seasonally) the Aran Islands. Most travel within Ireland is by road.

What are Ireland's domestic flight routes?

Who are the airlines for Irish domestic flights?

Are flights from Ireland to the UK considered domestic?

No. Ireland and the UK are separate countries, so flights between them are international. The Common Travel Area lets Irish and UK citizens travel between the two without a passport in many cases, but airlines still require valid photo ID.

How do I fly to the Aran Islands from Ireland?

Aer Arann Islands operates short flights from Connemara Airport (Inverin, NNR) near Galway to Inis Mór, Inis Meáin and Inis Oírr. Flight time is about 10 minutes. Ferry services from Rossaveal and Doolin are the alternative.

Who operates Ireland's domestic flights — Aer Lingus or Ryanair?

Based on Kiwi.com booking data (last 12 months as of May 2026), Ryanair carries the larger share of Kiwi.com Irish domestic bookings (71.2%) versus Aer Lingus (28.9%). Both fly the limited domestic and Ireland–UK network; Ryanair tends to be cheaper on shorter advance bookings.

How long is the Dublin to Kerry / Donegal flight?

Dublin–Kerry takes about 50 minutes; Dublin–Donegal is roughly 1 hour. Both routes are operated mainly by smaller regional aircraft on public-service contracts.

How early should I arrive for an Irish domestic flight?

Aim for 90 minutes before departure with hand luggage, or 2 hours if you're checking a bag. Dublin Airport security can get busy during morning peaks — give yourself extra time.
