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.

There was a very drunk and disruptive passenger who was on the plane, right behind me. He was already drunk before boarding but was still let on the plane. He kept kicking and hitting the back of my chair the entire flight. It was an early morning flight and had zero rest on that leg

There was a very drunk and disruptive passenger who was on the plane, right behind me. He was already drunk before boarding but was still let on the plane. He kept kicking and hitting the back of my chair the entire flight. It was an early morning flight and had zero rest on that leg

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.

I didn’t realize Aer Lingus was a “nickel and dime” kind of airline where you had to separately buy all the amenities you wanted. The push to purchase duty-free beauty products was off-putting. And our row had the least amount of leg room I’ve ever dealt with on a flight.

Loved it! Best airline to fly with. Nice crew, good planes, good food!

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.

The seat was very uncomfortable. It helped to use the foot rest. Could not sleep because of the seat.

The seats are incredibly uncomfortable. My luggage didn't make it on the flight from London to Nashville.

The plane itself is old and way overcrowded. The crew do a great job of trying to mitigate. It is just uncomfortable for over 8 hours, bearable, but barely. Boarding, and the baggage game, is ludicrous. Why charge extra to check bags when there is not enough room for everyone to "carry-on" and checking is needed? I do not think these issues would be different with other airlines, I believe it is the attitude that squeezes every penny out of each traveler.

Expected a lot better service paying for a business class seat. Seemed to be short on staff and did not get the service I expected.

Nice experience. Baggage arrival in Mumbai wasn't that quick and needs improvement.

I flew Club World and was SHOCKED at how totally absent the crew were for the duration of the flight. So much so that we received no drink service other than the post-departure cocktail and that was it. Wasn't even offered tea/coffee and the in-flight attention was so bad that literally minutes before landing the one crew member for our row was scrambling to pick up left-behind water bottles, glassware, trash. And the rest of the crew had already stowed all carts, he was cramming the trash into the lavatory trash can and was stashing the glassware frantically in the galley as we were on final approach. He was so scrambled he left two overhead lockers wide open (that he'd opened) for landing. Unbelievable!

Paid for first class and was surprised that the seats were the same in economy except no one was in the middle seat. I expected an actual first class seat.

The flight was several times changed. That was inconvenient, to sah the least.

They lost my special meal request and tried to tell me I didn't request it. I had the proof. Then they tried to get me to eat food I can't eat. No apologies

British airways keeps canceling our flights. I won’t be booking any future flights with them
