Top tips for finding cheap flights to Ireland

  • 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.

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.

This flight was delayed and caused me to miss my connecting flight from New York to Boston. I had to rent a car and drive myself home to avoid waiting another 5 hours in the airport.

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.

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.

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

Very long and took extra push back to BA staff to get a realistic flight after they made me miss my original direct flight. Eventually landed 9 hours late and incurred many extra costs with other missed bookings

They overbooked the flight by 3 people. It is completely unacceptable to tell 3 people, with paid tickets, that need to get home for children etc, that they need to stay another night. No compensation. No apology.

It was a short flight but everything was great! I would fly with British Airways again.

Delayed flight due to lack of crew caused me to miss my connection

Please make sure the number of seats matches the number of overhead bins and passengers don't carry on more than one bag.

It was difficult to board from London to accra. Had to get there an hour before and almost missed the flight. Did not get enough rest time at the lounge

Seating is tight if you don’t upgrade. Food was decent. Boarding and unboarding was efficient. Smooth flight. Could make upgrades more affordable

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.
