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).

  • Which flights to Ireland should I look at if I want to see the Rock of Cashel?

  • Where can I see the Book of Kells?

    The Book of Kells Exhibition is located in Trinity College Dublin, so the nearest airport is Dublin airport.

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.

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

Probably my favorite airline and way to go to Europe. Everything went smoothly! Food was tasty, crew was pleasant. Really cannot complain!

Golf Bags never made it on the flight. Very expensive golf bag and. Clubs,shoes, clothing. Will file a claim against Aer Lingus

Horrible. Garbage airline. Due to the strike we got a replacement plane/crew. I didn't get my exit row seat I paid for. Food was horrible. Plane was hot and didn't have AC vents.

The first leg of my 2 flights were delayed, causing me to miss my second flight and have to stay the whole night in Dublin. Super upset with this experience, and I still need to figure out how to get compensated for this.

Everything went well, but could have used a bit more legroom.

The flight got us safely from point a to point b and on time. For a transatlantic flight that isnt nothing. Flight crew was kind and professional. The seats are super uncomfortable (worse than domestic budget airlines) and the cabin was DIRTY.

Long unexplained delay, uncomfortable back row, long waits for trash collection.

Great service on the plane and by ground staff. great prices. I was able to change seats on the plane. The allocated seats cannot be changed when checkin in online. They have to be done at the airport if you check in at the airport or on the plane by asking a stewardess / steward.

The seats of the Boeing 787-10 Dreamliner were ridiculously uncomfortable. I was on 10 flights during this vacation and this plane was super uncomfortable both times I was on one whereas all of the others were perfectly fine. Additionally, these planes do not have any air vents that passengers can control, the climate is entirely controlled by the crew which made for an extremely uncomfortable temperature for the duration. The flight attendants tried to make everyone happy with the temperature but several people you could tell were excessively warm and just wanted a bit of airflow.

Everything was fine except not posting the gate number until 14 minutes before boarding. In an airport the size of Heathrow, that was unacceptable.

We already had a five hour layover in London, and then they cancelled our flight about half hour before we were due to board. They wouldn't give us access to the lounge and hanging around the extremely busy terminal for another three hours until our next flight was crappy. 8 hours in a busy terminal is awful. The least they could have done was give us access to one of their quiet, comfortable lounges for the inconvenience. I heard from others that they do this a lot -- cancel these short flights if they're not completely full. When we got onto the next flight it was absolutely packed and uncomfortable. Just very disappointing. British Airways used to be a great airline to fly with, but it doesn't feel that way at all now.

Don't fly thru London Awful and huge U need 4 hrs to transfer cuz u have to tale buses to and fro from airplanes Bad business

Staff with low service level, forgetful. Temperature at 15 C and after asking twice to raise the temperature the crew did nothing.

Economy extremely cramped. Dinner was not good. Breakfast was quite good. Crew was excellent.

They took good care of me on the plane and had it not been for handicap assistance I would definitely had missed my connecting flight . Not BA fault but The airport security instead . Two hours is way too long for security

The least comfortable business class seat I have encountered for a while - very very firm when reclined making sleeping difficult. Cost cutting is visible everywhere - no offer to refill drinks (the wines were not good - so no real issue there :) ) Just not worth what BA charge

old seat need to go! outdated and uncomfortable. I waited 40 minutes for my bag

They had about 20-25 people overbooked. Including me. Why is this?? I was put on a flight to NC an hour later with a 4 hour layover. I was supposed to be home at 1045am instead i was home at 7:30pm. An extra day to pay for dog care.
