Top tips for finding cheap flights to Ireland

  • Book at least 1 week before departure in order to get a below-average price.
  • High season is considered to be June, July and August. The cheapest month to fly from London is January.
  • Morning departure is around 11% 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.

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.

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.

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.

Flight was great. Had to wait almost 100 minutes for luggage (some problem in the delivery). This may not be an Aer Lingus problem, but an SFO problem.

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

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.

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.

Reliable, great value, but not outstanding in any aspect. This is similar to the experience you get in most international carriers like Etihad or Delta.

Aer Lingus was the actual airline so they handled everything professionally.

Flight got diverted because of an emergency and the crew were fantastic and probably saved that passenger’s life. While in emergency landing some measures could have been taken to prevent additional delays. In general not great experience with BA. I used to fly BA years ago all the time, very disappointed by the whole experience, seats were tight, bathrooms tight.

Business class area too small and chair and equipment not comfortable .

Lost my luggage in London Was double charged for luggage

BAD!!! due to delay I missed my connection in MEX, had to pay for hotel and new flight for next morning increasing my spent for $1,000 usd

Boarding could have been better organized. The one member of staff disappeared for a while so boarding by group relied on honesty.
