Top tips for finding cheap flights to Ireland

  • Morning departure is around 45% more expensive than an evening flight, on average*.
  • When flying from London to Ireland, you will be lucky enough to be able to use any of the London-serving airports for the trip. Heathrow (LHR) and London City Airport (LCY) are the two airports that are closer to London central and are good choices if you are based centrally. Gatwick (LGW), Luton (LTN) and Stansted (STN) are all slightly further afield, so take into account your ground-travel time when planning your itinerary.
  • If you would like to take some great British treats to your Irish friends, all London-serving airports offer great duty-free shopping options. Heathrow and Gatwick have convenient click-and-collect services, which can reduce time. Simply browse online and collect at the designated point of the airport for a seamless transaction.
  • Although your flight to Ireland from London will be rather short, if you have a baby, you may want to ensure they sleep comfortably through it. If you fly with British Airways, you can get a bassinet for your little one, to get them down before the plane takes off. All London airports will also let you board first if your baby is under two years of age.
  • If you are planning on visiting Dublin, ensure your flight arrives at Dublin Airport (DUB), on the western coast of the country. You can also catch flights to the central region of Limerick and land at Shannon Airport (SNN) or the southern region of Cork and land at Cork Airport (ORK). Although Ireland is essentially small, direct city-to-city flights are always good if you don’t have the time for ground transportation.
  • If you are planning on taking your service animal on the plane, be aware that, although this is welcomed, you will have to follow the procedure of alerting the airline at least 48 hours before the flight, making sure the animal’s paperwork is up to date and they have all their latest inoculations.

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.

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.

Both flights were delayed due to maintenance issues. Because they where late boarding all four of our bags where left behind on our last connecting flight.

Aer Lingus interior is not the cleanest. I've seen crumbs on the seat and wrappers on the floor when I boarded

Flightl was good and on time. Only problem was the quality of the air in the cabin,didn’t appear to be clearing the air circulation.

The transatlantic flight was wonderful. The regional reminded me of jet blue. Crazy and packed. Not enough overhead space and tough on elderly.

They lost my baggage on my connecting flight and we’re an hour late so I nearly missed it

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.

The flight boarded and departed Venice on time (more or less), the cabin crew were super friendly and efficient, the flight crew kept us informed of progress, and the flight arrived early in Dublin. All in all, this flight was as close to perfect as is possible to achieve. Well done, Ryanair. The fact that Ryanair aircraft arrive and depart from gates that are in the back of beyond in Dublin's Terminal 1 is a bummer - in terms of the length of the walk need on both ends of a return flight. But I suspect that this is not Ryanair's fault

Enjoyed our flight with Ryanair to Arrecife. Flight boarded pretty much on time, crew were welcoming and very good. Generally good for a frequent low cost flight, Seats could however have been more comfortable.

I wouldn't like to fly with them anymore, I don't like their service, you can hardly take carry-on luggage because they charge you for everything, you can't ask for a glass of water, and the flight attendant tells you that they don't have any, that you have to Paying 3 euros for a bottle of water horrible, I don't recommend it, and they don't have anything low cost, because the plane ticket may not be expensive but what they charge you later for the rest, the flight becomes more expensive, it's the only airline that I don't like it so far, and I traveled a lot.

Staff were friendly and flight was on time. Free drink and snacks would have been appreciated.

The boarding process was fast and easy , but the airport sign was not up on the board, so it was hard to know the correct gate , on the airplane there was NO Snacks and NO water …. Everything needs to be purchase …. It’s not worthy for the price we paid !

Booked through you used Kiwi who did not complete checking in until 24 hrs before departure when the check in was available 48 hrs before hence we sat separately. I will not be using you again.

The crew was very attentive and kept busy serving a variety of treats!

Terrible. Missed my flight to final destination because of delayed British Airways flight. Had to spend 12 hours in airport and $1500 for new plane tickets

The crew on board were all very pleasant and happy to help. The flight had the old business class seats. The departure board in the business lounge did not update and kept on saying ' gate open' but never said boarding. When I got nervous about the departure time and walked to the gate I was told off rudely for being late.

Offered vegetable curry when it was actually tofu which I don’t care for.

The flight was good the crew excellent…but take off delayed three hours!!!

The boarding process was a disaster. No one respects the boarding groups—tired old aeroplane. There are no sockets to charge phones. The cushion seats are ancient and hurts back and gluts

Check in process was unfamiliar. While receiving assistance the employees supervisor berated him for not walking the area. Lucky for us, he ignored her and helped us check in. Did not know about the baggage fees with economy basic and spent 450 GBP (nearly$600) just on bags for a total of less than 2 hours flying time (50 minutes one way) on a round trip lasting less than 3 days. Customers check their own bags at kiosk and place on conveyor themselves. No reason for such an high cost of checking bags when customers do half the work. Some destinations it’s unavoidable, but will definitely seek other airlines before British Airways for future travel. Astronomically high price for bags. Our first experience flying British Airways and very, very disappointed. Completely overpriced for the services we received.

Both mine and my husband's chairs were broken. Also it took 2 hours to get our bags after our flight which was wild.

Having traveled from Canada through Seattle -London-Edinburgh with only carry on ( to keep trip uncomplicated ) We had to check our hand luggage at the gate as flight was full This was really annoying since due to their late flight in from Seattle we’d missed our orginal flight to Edinburgh and had been put on a flight four hours later We had no checked luggage with no need to go to the baggage carousel Very annoying
