FAQs for booking flights from the United Kingdom to Ireland

  • Do I need to use my passport to enter Ireland?

    Ireland, along with the UK, is a member of the Common Travel Area. British citizens travelling from the UK will not require a passport when entering Ireland. However, Irish immigration officers will look at your ID when you arrive in Ireland and may ask to see your passport, especially if you were not born in the UK. If you hold British Citizenship and use your passport to enter Ireland, you do not require a visa. Just ensure that your passport will be valid for your entire stay in Ireland.

  • Which flights to Ireland should I look at if I want to see the Cliffs of Moher?

    The Cliffs of Moher are located on Ireland’s west coast, so you should look at flights to Ireland that fly to Shannon Airport, which is the primary airport serving the west coast and also the closest. From the airport, you can hire a car and drive approx. 1h, take a taxi, or travel by bus (approx. 2h 40min, the journey is not direct).

Top tips for finding a cheap flight out of the United Kingdom

  • The 5 main international airports in Ireland are: Dublin Airport (DUB) on the east coast, Cork Airport (ORK) on the south coast, Knock Airport (NOC) in the north west and the airport of Shannon (SNN) on the west coast. Each airport is the primary airport of its respective region, so you can choose which flights to Ireland suit you best based on where you would like to visit.
  • Certain airports in the UK also offer flights to Donegal (CFN) and Kerry airports (KIR). These airports are less busy but may only have very basic facilities.
  • Dublin Airport is probably the best one to fly to if you would like to visit multiple cities, as it offers the most options when it comes to domestic flights throughout Ireland. Cork Airport is also another good option.
  • Car seats are mandatory for children from 8 months to 4 years old when travelling in a car, so you might have to bring your own or rent one if you are going to be travelling by car in Ireland.
  • The best way to travel around Ireland is by car or public transport, given its size. However, you may need to take a plane to visit the Aran Islands from the mainland.

Are Longus was fine. I booked thru Kayak and was unable to get my business class seat early. Sat next to galley. Crew forgot to wake me for breakfast.

I was pleasantly surprised - it has been awhile since I traveled with them - other than being delayed leaving Malaga everything ran very smoothly- yes I would travel with aer Lingus again and yes I would recommended

I loved how they arrange boarding (starting with people seated in back and moving to the front). Flight crew was very polite and welcoming. Seating was ok, I felt like there was enough leg space however it is noticeable when the passenger in front of you sets their seat back.

Flight staff very friendly and helpful where possible. Late flight and travelling with young child, cabin lights remained on for the duration of the flight which was a little disappointing considering the time of the flight. Overall very happy to travel with Aer Lingus.

Nice to be on a flight that wasn't fully booked so there were only two of us in the three seat row.

The only problem was there are games on the entertaiment system. The guy behind me played poker the entire time and poking the back of my seat. I hope they remove these.

Delayed due to weather... fine. But then the board us. Rows 15 and back had to go down the stairs and back up the back stair entrance to the plane. No assistance offered. Then they inform us that we are delayed for paperwork for an hour. So why did we board? Then, about 45min later they inform us that it'll be another 60-90mins. Really? No wifi, no seat entertainment, no drink or snacks offered. And we were not allowed to deboard.

Great travel. Wonderful experience. Hope to do it again in the near future. God willing

Aer Lingus doesn't have plug ins for devices at each seat. They also did not give me a dairy free meal as requested and confirmed by staff. It was as if I had not requested anything. Otherwise, they were great!

There were a lot of empty rows. As a single passenger I should not have been seated with 2 others. The WiFi didn’t work. The Kosher meal was awful.

Very good, everything went straight forward, boarding, during the flight, landing and all on time Well done

flight delayed, no information given until late on, Ryanair app said "on time" until 5 minutes before expected departure time, crew rushed us to board, when it was already 3 hours late

I got denied boarding bevause they said they "ran out of seats on a plane"

Speakers were blaring. It's like being in a Moroccan market and you keep getting shouted at with what's for sale

We missed the flight due to very slow security control and lack of last call announcement. We only found out at the gate that the gate is closed. Altogether 14 or 15 people missed the flight FR4500 from Cologne to Dublin.

Everything went according to plan. Check in, boarding etc all were very efficient.

What can you say Ryanair get you there,no frills Not so cheap anymore ..... but what is now days! Would use again as always. Good flight times for us.

Very unpleasant staff, disgusting service, ignoring requests, refusal to help

Late again rude staff at gate bullying passengers made us stand in the cold 3degrees for 40 mins before they let us board

The usual average Ryanair flight, but we landed 20 min before due time, which was very good.

Boarding good. Seats uncomfortable when lie flat. Food was awful. Tasted stale and chicken was dry. No live tv or flight map. Had to pay for internet.

Poor technical details on this plane. 1) There was no WiFi on an 8 hour long-haul flight. So no work could be done. That's below the standard expected for airlines these days. 2) The power outlet at my seat was busted and not working. 3) The headphone jack was loose and I had to keep adjusting my headphones to get good reception, or when it slipped out. - The flight was delayed to due mechanics. Sometimes this can't be avoided, I understand, and it's a big inconvenience to arrive that much later when traveling across time zones (then arriving at 4am from the prior time zone). - Also unique to this flight, the northern lights were visible on the right side of the aircraft, but I only found out after we landed (b/c again no wifi). I understand there are considerations about people being out of their seats to look, but I feel extremely disappointed and resentful that I wasn't told so that I could have a chance to look at this probably once-in-a-lifetime cosmic event from a view in the sky. - Flight crew was otherwise friendly and helpful.

Our flight was delayed by over 6 hours. We then had to deplane, stay overnight in a hotel then fly out the next day, 23 hours late.

I would have preferred something lighter for the second meal. Maybe a small sandwich .

They cancelled our flight the morning of departure at 4:30am.

Flight bumpy but good. 1 hr 20 mins for luggage not so good.

We were told to check our bags at the last minute, and the communication was poor.

Lost our luggage in Heathrow. Showed up 3 days into a 7 day vacation. Very inconvenient and disappointing!!

My luggage never arrived to Zurich. They can't confirm when it will arrive

Late again. 3 out of 4 late. One cancelled flight and one lost bag.
