Flights from North America to Ireland: the best tips from KAYAK users

Insights shared by verified travellers who flew the route from North America to Ireland 
Verified travelerFlew with Aer LingusORD-DUBApr 2025
Security at OHare airport is a bid shambolic. Not enough space for the amount of people trying to process.
Verified travelerFlew with British AirwaysCLT-DUBOct 2024
Charlotte airport was very good. Dublin is very nice. Attendants at both airports were very helpful. A good experience over all.
Verified travelerFlew with Aer LingusLAX-DUBJul 2024
Go to the airport early, LAX is the worst airport to fly out from. There is just so much traffic on the way to get there. We used the flyaway option in van nuys, ( buy your parking ticket in advance) costing us only 115 dollars for parking for over two weeks and it’s very secure. The buses go every 15 minutes from there directly to LAX. Best way to get to and from LAX. Check in was easy.
EvgenyFlew with Aer LingusYYZ-DUBJul 2024
Check if the airline workers plan to strike
TFlew with Aer LingusIAD-DUBApr 2024
Stay on the other side of the river Liffy from the temple bar area. You can walk everywhere.
BarbaraFlew with Aer LingusBOS-DUBMay 2024
Pack what you need in a carryon since it is likely you'll arrive without luggage.
Verified travelerFlew with Aer LingusBOS-DUBApr 2024
Be prepared to be fed/served a lot of food :)
Verified travelerFlew with Aer LingusEWR-DUBApr 2024
JFK is an amazing airport, they have TSA precheck which was not offered when I flew Aer Lingus/Newark. The TSA precheck line took a long time, they only had 2 machines and a few agents working. Other than that Newark was as any other airport, easy bag check in process and gate seating area was clean and comfortable.

Airline reviews

To start, I’d like to say that every American Airline personnel I interacted with on the ground, especially flight crew, was very friendly and did their best to help me out. Despite this, however, my experience with the airline was an entire mess. The 7:19 PM flight was heavily delayed due to weather, and pushed to 10:30 AM the next morning. Because of this, I had to spend the night inside of the airport. At some point later in the night, I got an email saying that the flight had been canceled. I called the support number, and the representative on the other line told me that the flight was still on and that I didn’t need to rebook. The next morning, no one came to the gate to open the door for the crew until almost 11 AM. By this time the flight crew had been waiting for over an hour, and they had called management to get someone to open the door for them multiple times. Around 11:30, the gate screen had changed to a different flight. I ended up buying a last minute ticket with Southwest airline just to get to Chicago, because the next flight with American wasn’t until 7:19 pm that day. Now, earlier that morning my suitcase had been sent ahead of me to ORD. I went to baggage claim to ask them if I could have my suitcase forwarded to where I was staying. The representative at SDF baggage claim said they could and put the claim in for me. As I was going back through TSA, I got an email that the airline had found my suitcase, but the next step was to send it BACK to SDF. I called the airline support number again, and I made it clear that my suitcase needed to stay in Chicago and to not come back to SDF. The representative told me that they would hold my suitcase at ORD and that it wasn’t going to be forwarded anywhere. Once I got there, I found that they had loaded my suitcase onto a plane to send it back to SDF. Thankfully, I had gotten to the baggage claim counter in time for them to put in a request to bring my suitcase back up. My refund with the airline is processing already, but because of this entire experience and miscommunication at every turn of the way, I will not book with American Airlines in the future.

Flight was delayed by 11 hours. Flight agent finally had to rebook us, but did not rebook fully correctly. We had to pay out of pocket to get to the hotel they booked us and couldn’t check in the next day online because the next day’s agent said they didn’t complete the process the night before.

It was as expected for such a short flight. No complaints

Overall flight was as expected. It would have been better with a couple options for snack instead of only one item and if there was a TV or music as option. But overall satisfied.

Deparature was late, which is annoying but the arrival was fine and the baggage came early.

horrible our connectig flight was late and we had to rush thru DFW to the next gate with 15 minutes time. Get to gate and its changed. no one knows whats going on . finally get a new gate and the plane has been sent back to the hanger . Boarded 4 hours after our original flight time and then sat at the gate for over an hour as the captian said the cargo doors were open and no one was in the airprot or on the ground to find out what was happening. this caused us to miss the first day of the tour as we missed our transfer and hotel meetup no apologies or accomodations offered to assist

They could have done a better job announcing the boarding groups and asked for more drinks (water) if needed.

The boarding process was incredibly slow, as was deplaning. They started beverage service and there was an extremely small amount of turbulence, so they discontinued it. They said they’d resume if possible, but even thought the rest of the flight was perfectly smooth, they didn’t bother. Getting our checked bags took longer than I’ve ever waited and they couldn’t even tell us which carousel they were coming out on, so everyone was running back and forth for 30 minutes.

Deplaning time. Having to wait 10 to 25 minutes after boarding to leave the gate. Having to wait 10 minutes to park at the gate to deplane.☹️

Seats were very uncomfortable. I paid extra for a seat with more leg room, the seat was no different than a seat at the back of the plane. Flight attendant was rude.

We never had an experience they canceled the flight and they did not offer us an alternative flight. I had to book one on my own expense. They offered us food voucher and we could not use them at the airport it kept saying not attached to an existing flight. The people at the counter were rude and cold and they did not care about our situation

Will never book through you again. Very disappointed in the notices and action taken or provided when planes are rescheduled, enough to cause missed connections

They delayed flight because lack of staff then missed connection. Never flying with kayak or weather

Experience was good. Was surprised they didn’t offer a complimentary meal on a 5 hour flight.

it's all good nothing you can do make better 😌

Scrooge airlines spoiled my last chance at Christmas with my 95 and 92 year old folks. and rest of the family in Calgary. Ticket personnel would not let me on without a passport and I always visit Canada with my enhanced driver;s License when I travel from the US

Original flight canceled and communicated poorly. A series of gate changes , delays and plane changes followed. Even after the entire flight boarded there was another plane changes followed. Food vouchers provided to my travel companion but not to me despite being on the same reservation. No in flight entertainment. The entire experience was terrible although the flight crew were great.

We booked Premiere (their version of first class) and Premium Economy seats. We boarded an old swoop flight with all coach seating. No benefit to paying higher fare and no apology or reimbursement.

Delta was great. West Jet was not. I booked my flight in Sept (well over two months ago), but was told there were 2 reservations and NO tickets for me, my husband and 16mo daughter. We were unable to go ahold of West Jet over the phone and the kiosk was unhelpful so we had to buy completely new tickets in order to get home that day. I’ve called West Jet twice since and sat on the phone for over an hour without speaking to any representatives

more room between seats. will check out other airlines. uncomfortable - knees crammed against seat ahead

I had a nice flight with free wifi. So I was able to message family members and stream music during my flight, which made the trip go by fast. I also enjoyed flying on there Airbus A220. The plane looked very new and it also got up to speed fast down the runway and didn't need much runway to get airborne.

The take off was delayed as we were told that the baggages had to be rearranged to balance the weight. I only took a carry-on and a personal item, but the overhead bin was extremely small, even a normal size carryon can’t fit it, so they had to check it in for free. The seat was really tight and no entertainment at all.

They announced before boarding that the flight was full and there would be limited space in the overhead bins and you could check in for free. We did and after we boarded the plane found it was not full and there was plenty of space in the overhead bins. I’m not sure why they made this announcement.

We had a lot problems in beginning but Air Canada took very good care of us

1. The PA system was painfully loud. 2. Overhead bin #33 was missing—I find this troubling.

Crew great, flights departed early. Is was a good travel day.

Do something about that crying baby the whole flight. lol

Regarding the onboard entertainment system: the dual audio jack is not compatible with a standard earphone jack, so I had to listen to the audio in one ear only. The airline should hand out adapters or replace the hardware. The touchscreen was flaky, sometimes it responded to touch, sometimes it didn't.

Crew was friendly and helpful; cabin seemed roomy even in economy class.

i know it's complimentary - but they didn't have enough snack for all the passengers. there was no entertainment or available WiFi

I believe it was short flight in plane I understand not that much compared to other airlines but weighting for checkin was too long need extra person for checkin or Atleast someone to let the customer knows don’t worry someone will be here shortly.

Seats were alarming close to the row in front of you. I didn’t do the measurements online, which I’m sure they’re available, but it seemed much tighter than other planes, but the airplane itself was well maintained and looked fairly new. My only complaint on the staff was that we’re on an international flight. Normally they give you wine with dinner and the flight attendant decided to pull some strict restrictions and wouldn’t give more than one glass of wine per person, and you could not share with your spouse, which seemed ridiculous when we have four people on the plane with us and only one person ordered wine asked for a second one and she said oh absolutely not. It’s only one per person Which on a transcontinental usually is not the case. They’re very attentive on making sure everyone is as comfortable as possible.

Boarding seemed a bit chaotic and we had to walk outside across the tarmac. Passengers of all ages had to drag carry on luggage up the outside stairway into the aircraft. There was no WiFi. Very uncomfortable crammed seats. Glad in-air time was only an hour!

There was no flight. I booked a flight from Toronto to Bordeaux with a stopover in Dublin. I arrived in Dublin and the flight number I had didn't exist and the flight going to Bordeaux I wasn't on. I had to book a new flight with a different airline for later in the day and pay out of pocket.

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.

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.

Friendly crew who apologised and explained reason for delay. Good on board service. Rather cramped seating. Late departure.

Boarding was delayed and we had to get on buses to plane so group # didn't matter. No food or drinks served gratis. Seats were small, knees smashed into the seat ahead, didn't recline. Crew was excellent though.

Flight was delayed and there was boarding pass and flight information errors resulting in confusion and stress

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

Poor BA get a lot of stick and have some problems getting your bags to the same destination BUT the whole experience is very much 5 star and probably due to excellent, helpful and sooo British staff. We travelled in economy plus.

The luggage is still in transit and the ground staff at Heathrow airport very rude and uncooperative. If I was you, I would fire them straight away. Bunch of incompetent folks.

Flight was fine, food better than anticipated and flight attendants were helpful and friendly.

Economy extremely cramped. Dinner was not good. Breakfast was quite good. Crew was excellent.

Food was pretty good and crew did ok. Boarding was a disaster. Seats and leg room were not conducive to a comfortable flight, especially if you are 6’3” and have the person in front of you leaning their chair all the way back for 9 hours and your are told they are allowed to do that.

Excellent service smooth flight f or the most part food was right now.I'm expectedly good.

They denied us boarding on our scheduled flight and experienced significant disruption to our travel plans because of overbooking the flight!
