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 
DaveFlew with Aer Lingus-Sept 2026
The Dublin Airport has NO rail service, so if making a rail connection, solid plans need to be made beforehand about where to go and how to get there.
IsabellaFlew with United Airlines-Sept 2026
My only tip is to put a small bag underneath bc you won't have room for much else.
Verified travelerFlew with Aer Lingus-Sept 2026
Look at the airport map first as you can easily go the wrong way in Toronto airport
Verified travelerFlew with Aer Lingus-Jun 2026
Flying direct to Dublin and using it as a hub to other European cities is fantastic; far better than going thru Heathrow, DeGaulle or Frankfurt.
JonathonFlew with Aer Lingus-Jul 2026
Don’t sit on the inside seat during a lay flat flight. Don’t order the beef short ribs, they’re kinda fatty, and chewy.. Try all the whiskey.
Verified travelerFlew with Aer Lingus-Jun 2026
Avoid Toronto airport if possible. One had to leave the airport to go to the next terminal. No directions.
Verified travelerFlew with Aer Lingus-Apr 2026
Make sure to double and triple check that the flight you book actually exists before going to the airport.
Verified travelerFlew with Aer Lingus-Jan 2026
If flying to Ireland, the direct flight from SFO to DUB on Aer Lingus is the way to go to avoid the hassles and uncertainty of mid journey stop-overs.
LisaFlew with Aer Lingus-Dec 2025
Look at Jet Blue and Delta. May be a bit more expensive but keep an eye out for fare reductions and book early.
DavidFlew with Aer Lingus-Dec 2025
Check gate; it’s not in the international terminal
Mary MargaretFlew with Aer Lingus-Jun 2025
Some people may be required to check their carryon bags, depending on flight, plane size, check-in crew, etc. Also, taller people should purchase aisle seats.
Verified travelerFlew with Aer Lingus-Jul 2025
Whatever airline you choose, spring for a class with more leg and overall body room than economy (or whatever the cheapest class is called).
himanshuFlew with Aer Lingus-Jun 2025
Eat and drink before boarding. Snacks. Hand gel and surface wipes . Don't expect a window if in a window row.
JudyFlew with Air Canada-Jun 2025
Seat room is very limited with econo. No need to pack snack…food provided.
Verified travelerFlew with Aer Lingus-Jul 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.
Verified travelerFlew with Aer Lingus-Apr 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.
BarbaraFlew with Aer Lingus-May 2024
Pack what you need in a carryon since it is likely you'll arrive without luggage.

I could clearly see the difference of Air France from Atlanta to Paris and then from Paris to Bengaluru. To Bangalore the WiFi was not free and even the flight seemed an old one, I am just curious why.

I could clearly see the difference of Air France from Atlanta to Paris and then from Paris to Bengaluru. To Bangalore the WiFi was not free and even the flight seemed an old one, I am just curious why.

The flight lead, Katherine, took care of me in business class and provided exceptional service. She was warm, welcoming, bubbly and proactively accommodating as well as confident, professional, competent and clearly respected by the pilots. Just what I needed on my 17th and final hour of flight time traveling home from a business trip to India.

As per usual when you Hit the UK it's a slow process through customs Not as efficient at Thailand for sure

Couldn’t get boarding pass in SLC even with help from a redcoat, so had to find a desk in AMS to get boarding pass. Technical problems so not sure why. Very inconvenient. The KLM app is not as user friendly as most apps. Also had to wait almost an hour on the tarmac for a fuel truck, which caused us to miss a connecting bus in LUX.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

Overall very poor. Flight was disorganised, staff were rude and this is my second experience with KLM that I've had baggage go missing. It feels like, if you are an economy customer, KLM staff do not show you any care. I shall never fly with KLM again. Worst airline in Europe

Overall a very pleasant flight. No significant issues on either flight. Amsterdam airport is very convenient for connecting

The baggage service at Malpensa was the worst ever. We wanted for over an hour without any information, they broke my suitcase, and the services of the local luggage services company was below any usual services level of a KLM partner.

I travel frequently. The flight was late again... KLM should really try and be on time

The plane was clean and the staff was friendly. Food and drinks as expected on international flights. The entertainment system was old style, with a pullout controller, and selections not as extensive as on other flights.

I initially boarded in a very comfortable and large plane and was told there was a mechanical issue with a waste receptacle. We sat on the plan for a good few hours, then were told we can deplane and that we would take off shortly. Delays continued and four hours later my flight was cancelled, and I had to quickly rebook another. The flight I rebooked was also delayed, and I when we boarded, I wound up on a small plane in a middle seat for the 6-hour journey and it was extremely uncomfortable. No issues with the staff in any way, just the overall experience of the delays, cancellations, and downgrade in comfort on such a long flight. It is significantly impactful on how you feel post travel and I was exhausted and sore from the experience.

It was pretty good, they give a small blanket, neck pillow and earphones. The only bad thing was not big enough leg room for your bag and feet. They gave us a snack, dinner, and breakfast on flight and food was good considering it was on a plane

I bought this ticket for my daughter. She had to pay for her carry on bag to be checked. My understanding is that transatlantic flights included carry on and personal item The nickeling and diming fo legacy carriers has stooped to an all time low. So sad.

Great other than a couple very drunk guys that for a while kept bumping my seat from behind. The staff did their best to control them. Even refused serving them alcohol and allowed the gal sitting next to them to move.

I do prefer to fly United and have always had excellent service, except for bad weather. Flights are on time and staff is alway curtious and helpful

Wonderful and fast TSA checkpoint. The line was fast and our gate was close by

Delays from united along with Newark air space caused delays. But an average flight! Unfortunately we come to expect delays from the airlines.

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

No entertainment system or wifi on a 12 hour flight. They failed to include GF meals And snacks as requested on my ticket so I had very little available to eat. Crew seemed indecisive.

We were already two hours delayed before take off and then had to be diverted. Terrible experience.

entire boarding process from the moment we entered Naples Airport was terrible

The legroom, seat width, inability to book my seat with the airline in advance when I paid extra to do so, the food is extremely plain and small. The cups of tea and coffee are small. Not to mention I had to pay for a g&T when I paid over $1k for a one way flight. Sheep travel better in a transporter.

We loaded a little late, then sat on the tarmac for 1.5 hours, thus missing our connecting flight to the US. Naples airport was run very inefficiently. Overall, confusing to find the Aer Lingus check in. Staff on the plane were pleasant. The staff in Dublin did their best to help with hotel for the night. They booked us on a Lufthansa flight the next day, they said, but no e-mail or text was sent, like they said it would be. I later spent 40 minutes on a call to find out ANY details of our flight the next day. This may have all stemmed from a problem with the Naples airport, but frustrating nonetheless!

Flight was delayed out of Naples, causing us to miss our connecting flight. We were told our luggage would follow us to our final destination. We arrive at the layover airport, where we see our luggage on the baggage claim conveyor belt (out of sheer coincidence). Had we not checked, our bags would’ve been lost. The last flight we were booked on was not specified. I had to research which airline and flight it was. Inexcusably poor communication and handling of the situation. Will not fly Aer Lingus again!

There was a 3 to 4 year old child sitting behind me with both her parents. She kicked the back of my chair the entire flight. Flight crew did nothing. There were no snacks or drinks offered on this flight. Only 1st or business class got anything. Don't recommend this airline.

Aircrew was very very supportive helpful funny and accommodating. The flight itself was very smooth the pilot was very informative and we were very comfortable with all of the accommodations and concessions that were given. Really liked the Hub in Dublin that allowed us to do US Customs before getting back into the US to eliminate extra hassle and Rush their staff was always accommodating and very informative with signage every step of the way

This was the worst experience I've ever had with an airline. For the first wing of our international flight, we were stood in a boarding line for an hour, which was taxing because I am disabled, and then my husband and I were split up, and I was placed at the front of the plane. A flight attendant took my bag from me, which contained much needed medicine, and placed it in the overhead compartment. Because I am disabled, I needed my medicine accessible, and without my husband to reach it for me, I was stranded. My husband had previously communicated this at the gate, and they moved his seat closer but still several rows away from me, and in a center seat where he couldn't easily get up and assist me. We would have even paid extra to select our seats and to sit together, but there was no option for this. Luckily another passenger gave up her seat so that I could be with my husband for assistance, but the flight was deeply uncomfortable due to the delay in my medication and the overall conditions of the plane. For the second wing of our flight, we had the same lengthy boarding line, and somehow my husband and I ended up in adjoining center seats, which were exceptionally uncomfortable. Additionally, my husband is 6'5'' and we were both placed in broken seats - mine was stuck in a reclined position, and my husbands was stuck in a cramped upright position, with our shared armrest being broken as well. Much of the front of the plane was completely empty, and another passenger had been moved up on request, but when I requested that we be moved up to empty seats, the flight attendant I spoke with declined, leaving us in broken seats and extreme physical discomfort for the duration of a transatlantic flight. Other services throughout the flight were spotty, including simple food and beverage service and trash pickup. Flight attendants routinely forgot my husband and I and only offered items to folks on the aisle seats, and when I requested water on one occasion (to take with my medicine) I was ignored. At the end of our flight, I was barked at by a flight attendant to put my seat back up - enraging because I couldn't as my chair was broken, and because my earlier request for an unbroken seat was ignored! If my seat needed to be up for safety reasons, then Aer Lingus' staff placed me at risk by refusing to move me to a seat where this was possible. It took us several days to recover from the physical strain of this trip - not at all what we had hoped, coming back from our honeymoon. Overall, this was a deeply unpleasant experience and my husband and I will be avoiding Aer Lingus as well as encouraging all of our friends and family to avoid Aer Lingus as well

Absolutely the worst at baggage handling. Our baggage still has not been delivered. They couldn't find it in Dublin then when we got to Edinburgh they said the 2 bags were sitting in Dublin. After spending an hour filling out forms at the counter. We left for our hotel, bags arrived in Edinburgh at 505pm using my satellite tracker. Tried calling the numbers provided, no answer to their 24/7 service. Next morning the bags are still sitting at airport, no movement. Called different number provided by hotel in Sterling, the said it's souly the responsibility of the courier service now and they couldn't help. Completely ruined our travel plans, we must find clothes to purchase today instead of going to the museums we had purchased tickets for. This loss is costing us thousands in already paid hotels and services. No one takes any responsibility. I'll be contacting legal services on our return. We will never forget and I'll be a social advocate to avoid using this service.

I was disappointed with my experience on my Aer Lingus flight from Denver to Dublin. One of the biggest issues for me was the attitude of the cabin crew. They came across as cold, unfriendly, and unapproachable. There was very little warmth or friendliness, and I rarely saw anyone smile. I did not feel that the crew made passengers feel welcomed or cared for, which makes a significant difference on a long international flight. The cabin was also extremely cold and uncomfortable. What made this more frustrating was that we were instructed to put everything, including our blankets, underneath the seats at certain times rather than being allowed to keep ourselves covered. Considering how cold the cabin was, this was particularly uncomfortable. I also did not appreciate the tone used when giving some of these instructions. At times, the communication came across as unnecessarily loud and abrupt rather than polite and courteous. I understand that cabin crew have important safety responsibilities and passengers need to follow instructions, but those instructions can still be delivered in a professional, respectful, and friendly manner. Unfortunately, the lack of warmth and hospitality from the crew was the most disappointing part of my Aer Lingus experience.

No complaints. Food was good. Seats had good electrical connections for charging devices.

not able to change flight, no customer service from KAYAK

Food abd wine was good and for the price this was a true bargain, relative to other transatlantic options. But it is still significantly behind my experiences with Air France long haul in both hard and soft product. But for the price air Canada to Europe from Vancouver is currently the best value of quality for the dollar cost.

Very good except paying twice for seat selection. Once when I booked and again when I checked in.

I think it went very well. We flew international and felt safe and well cared for. We were on time both leaving and returning.

No issues with the flight and flight crew. cleaner seats in economy section would have been better

We did not have seat assigned until almost the very end of boarding and my husband and I did not sit together I don’t know why even though we bought tickets 3 months in advance and checked in very early. We were not standby and we were treated as we had stand by tickets. I will never fly Air Canada again.

I didn’t get to go on my flight. I cracked a rib and tried to contact kayak Air Canada and United Airlines and everyone gave me the runaround. No one reached back out to me and I couldn’t go on my trip. I have used kayak in the past to book flights, but I will never do it again because that experience of trying to get a hold of someone to explain my situation was awful. Everyone gave me the runaround that I did speak to and no one was helpful and kayak was unreachable.

In flight entertainment is complex but extensive. The flight was 2 1/2 hours late-initially announced with 20 min delay-. Appears to have been weather related. Check-in staff very helpful. Needed wheelchair assistance-efficient in Boston, slow but very helpful in YUL. Given the delay would have appreciated refreshments on plane (more than a tiny packet of pretzels). Plane was clean and apparently in good condition.

We were an hour late on the flight back, quite inconvenient !

Flight was cancelled on the departure day. We had to drive an extra 250 km to make it to another flight that was also cancelled. Finally booked on another flight that was also delayed 1h30...weather was fine on all flight. Every delay because of technical issues. Horrible experience.

Waiting area not big enough for all the passengers, no airport lounge.

Really appreciated the care, attention and friendliness of cabin crew. Very comfortable, prompt and efficient flight.

People were nice. Seats are so cramped my knees had to be pressed into the seat in front of me.

Dreadfully long wait for bags at Dublin coming off an already late flight.

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.

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

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

The flight was delayed, and delayed some more. But there was more room on this plane than the one that flew oversees! There was no food or entertainment, but that’s ok, it’s a short flight

Was delayed for checks after evidence of bird strike, good call
