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 January, November and December. The cheapest month to fly from London is January.
  • Morning departure is around 4% cheaper 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.

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.

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

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.

Great customer service. Frequent updates from the pilot. Smooth flight. Good entertainment. Meal service.

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.

Good flight. Not a lot of legroom, but it was fine for a short flight.

I never made this flight but the staff helped to get me rebooked (see previous review)

The flight was okay, but legroom was tight for me and I’m only average height, although at 30” legroom is comparable with most other airlines. Not much room in the aisle either making the trek to and from the toilet difficult with passengers standing in the aisle. On the whole, it’s probably on a par with budget airlines and the ticket process extremely competitive.

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.
