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
JasonFlew with Aer Lingus-Oct 2026
Make sure you purchase travel insurance because odds are, they will lose your luggage.
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.

25 mins late. The flight attendants were chatting and laughing loudly at the rear, which was rather unpleasant.

25 mins late. The flight attendants were chatting and laughing loudly at the rear, which was rather unpleasant.

The cancellation was disappointing but the arrangement afterwards was prompt and efficient. The seats arrangement were good. I still need to read further the details of how to get the compensation. All the flights taken were 100% delayed, not to mention the one that was cancelled. I couldn't sleep much in the flight from Abu Dhabi to Hong Kong because the egornomic design of the seat is not very comfy. Although there is more leg room, the seat itself was too tight and too hard. I suppose it would be the design of the seat that needs further improvements. The service of the crew and the boarding was good. The food on the flight from Amsterdam to Abu Dhabi was better maybe because the flight was in the morning, the food feels much fresher to the palate. And it was tastier.

Flight lead was a gentleman with silver hair and he went out of his way to shake hands and interact with each passenger seated in business class. A medical emergency took place during our flight and he handled it with perfect poise and professionalism. He was gracious and confidently competent. Just what you want from a leader,

It was really nice journey i personally recommend klm flight

The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

I appreciate that KLM was proactive in informing me of the 2 hour delay which enabled me to replan my travel. It was a bit stressful not knowing whether my connection from Montreal to Ottawa was happening. But the ground and air crew did a good job at comforting and assuring me.

This portion of the flight was through Indigo. A local carrier. So all economy seating. No real service some refreshments for purchase standard economy stuff.

The food & entertainment really stood out in terms of quality. The nasi goreng & chicken satay were absolutely delicious. It’s great that KLM feature international cuisine.

Seats were comfortable crew members support was very good but AVML ordered or selected by us needs a lot of improvement.

Flight left a few minutes late, but that's it. I wish the seats could be wider and recline more.

All very good The food definitely lacks quality and at breakfast I was given a small muffin small orange juice and not even a coffee or tea were offered It would have been nice to have that first thing Apart from the food everything else was excellent

It was mixed. Some of the staff were wonderful, some a little surly. I also had some issues with my flights, and when asking for answers and clarity, no one seemed to really know things that really should be part of the knowledge available. My baggage ended up being "lost" or delayed, there just seemed to be a lot of confusion. The flights themselves were comfortable overall.

It started bad at the gate. We were rushing due to the plane transfer. Then when we got to the gate, we stopped for coffee and then they made us throw away $50 worth of coffee. Very upsetting. Then my daughter’s bag never got put on the plane, so I had to spend another $600 on clothing for her in Prague. Needless to say, this is a failure.

There was a delay in my flight so we missed our connecting flight. Now were in dubmin for the night and getting home a day and half later

Boarding was extremely efficient; I appreciated the back-to-front loading strategy. The instructions from staff were very clear and thoughtful, and they were friendly and generous with service. In-flight entertainment was top-notch.

Everything is good, but my luggage was damaged. How are you guys gonna pay for my luggage?

Great service, comfy seats on a greater than 10 hr flight. On time. Really solid. Thanks Aer Lingus

More availability of water/drinks and less of a headwind

Amazing and I can’t wait to fly with them again

Besides having our original flight canceled and only having an hour between our connecting flights, the actual flight once we made it to our gate was a good one.

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

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

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.

First time flying with UA and it was a great experience. Thank you

This was an older airplane. The cabin was constantly warm to hot throughout the 10 hour flight and there were no vents to personalize air flow. Also since it was an older plane, the material and comfort of the chairs were very uncomfortable. I left my flight with major soreness on my tailbone.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.

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

Again a nearly five hour flight and pretzels is all the food you get and all you can drink water. No electric plugs in economy. Staff was totally not caring. Delta next time

Missed the connection due to previous flight delay. Can't rate a flight I was not on

Plane should have entertainment, instead of people paying to use wifi

We are experiencing more delays with westjet than other companies. West jet used to be our favorite airline.

We booked a ticket with Budget Air and the receipt said economy. My older teen daughter is neurodivergent and took a carry on bag since the ticket said economy, but she didn't see that it said no bags on her boarding pass. She has low attention. She managed to fly from Prince George to Calgary. At Calgary, she was preparing to board her last flight and the women said you can't get on. She said you can't board unless you pay for those bags. She had a small backpack, purse and carry on suitcase. She said you have to pay $160 +. My daughter has trouble understanding. She said can you step out of line to think about what you want to do. Then she said we have to leave you'll have to catch another flight. She called me in tears. I asked her to pass the phone to the agent. She said the agent was refusing to take the phone and ignoring her. I finally calmed her down enough to politely ask the woman to take my credit card. I told the woman of my daughter's challenges and need for extra helps. All she did was lecture me on how we booked ultra basic and we should have checked. She took my number and charged my card. Then I heard her push the phone back to my daughter and tell her to get on. My poor daughter was scared and confused and had to fly in tears. No apologies.

Flight was re-scheduled for the next day. No voucher for a hotel offered. Boarding was delayed by almost 1 hour. No free meal or even water was offered on board. When tried to purchase a coke, was denied because they didn’t accept coins less than 1 euro denominations. A young male flight attendant was especially rude and unhelpful.

WiFi was not working. Zero entertainment. Did not receive a discount etc to make up for this.

Travelled with my mother in law and made sure she has wheelchair access. Very efficient travel. There was always someone waiting for her when she got off the plane

Flying is no fun anymore. Too little space. Too much carry on baggage slowing down everything.

It was fine. I had a lot of trouble trying to buy a seat. The Westjet website charged me and then didn’t give me my seat. I ended up keeping the seat I was assigned and hope that the charges didn’t go through.. they didn’t. But this problem with the website (trying to purchase a seat at check in) has happened a few times before. But overall the flight was good.

Great flight. Pilot was able to fully make up the 42 minute late arrival of the aircraft for an on time arrival in Toronto.

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
