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.

Gate agents kind of serious. Had to wait til arriving at gate to choose seats. Thankfully they did give us seats together! And grateful the honored our age, giving us seats at the front.

Very polite and helpful staff. Jet blue…ok, but not as helpful!..

Seat was very uncomfortable. The worst in all of my travels. It sagged in the middle, worse than anything any airline can offer. Not flying aer lingus again.

My Aer Lingus flight (booking ref # 2SU4LF) was the worst travel experience I have ever dealt with. My flight from Paris to Dublin was delayed by over 2 hours which caused me to miss my connecting flight back to the US. I was not able to be rebooked on a new flight for another 3 days. When I finally made it on my rescheduled flight, it was delayed AGAIN, causing me to miss my connecting flight from New York to Boston. At this point I decided to just rent a car since the next flight I would have been able to get in wasn’t for another 5 hours. It was a complete nightmare experience and I will never fly Aer Lingus again. I have requested a refund from the booking company I placed my order with.

Flight was cancelled. There were no Aer Lingus reps to help. I had to rebook my flight and find a hotel. Still had nothing from the airline.

They couldn't do through check-in for us. They took 2 hours to issue just one leg of the boarding pass. They had no idea to handle the case of passengers who travels to USA via Dublin airport. we had tough time time Dublin airport as boarding pass for the US flight was not pre-issued. Hope Aer Lingus will learn to handle such cases which they couldn't learn in in the past 50 years of the service.

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Very sad, couldn't stop crying. Was an hour delay in Ireland and when we got to Canada the flight was boarded and couldn't get on. Was the last flight of the day. Now in a hotel waiting on a stand by.I have to got o work, so I'll go first available while my son stays in the hotel til one's available

Both flights late. Almost missed connecting flight and flight staff not willing to help expedite us off the plane.

during a very rough flight, I was forced to sit in a last row seat, fell asleep, and was forced to return to my assigned seat after the turbulence. The stewardess then used that seat to sleep.

American Airlines seemed to run a 'dry' flight. No alcohol was offered at any point with meals. Breakfast was a bit tasteless. The 'hot pocket' whatever that is, was horrid breadish pastry with very little filling. Decaf coffee was horrid. Seats didn't seem as wide or spacious as usual, especually for a ten hour flight.

We found the bag drop/ check-in proceedure at T5 unnecessarily complicated. We paid extra for seat selection in advance and were allocated worse seats at T5. We found the check-in person was not particularly helpful although the the staff at the gate were super good.

Very dated plane. Seat was firm and uncomfortable. Entertainment system almost laughably outdated. Poor audio. Picture was always too dark.

The worst travel experience of my life. Boarding chaos, delays and disorganisation at every stage. The worst of many was sitting in freezing temperatures for 10 hours whilst asking all cabin crew to turn the heat up to no avail.

The seats on the plane and at Heathrow Airport are so uncomfortable

BA have long since lost their way. They are a budget airline without the budget fares. Everything from booking to boarding to flying to arrival is just plain ordinary. I fly BA if the only alternative is Ryanair who are even worse. Otherwise we fly KLM or Lufthansa who are so much better.

They did not provide free WiFi, It could be purchased for, I think, around $25, This seemed excessive.

Good flight, awful, vindictive, vile customer services in T5 Heathrow.

Denied boarding passes for connecting flight. Missed connection as a result. Customer services T5 Heathrow airport vile, arrogant people who lied to us and threatened us.

Ok we did get an upgrade and the flight was delayed 45 minutes BUT without any bias. The crew were excellent, friendly, efficient and verging on exuberant, they all were so happy to do their jobs. Food excellent and the new safety video is fun to watch.
