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 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.

Check if the airline workers plan to strike

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.

Be prepared to be fed/served a lot of food :)

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.

Miami lounges were overcrowded and we were unable to get in. We only had a short time. But the banks are too tight in all American hubs

Miami lounges were overcrowded and we were unable to get in. We only had a short time. But the banks are too tight in all American hubs

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.

My flight attendant was attentive! The elderly person next to me was flatulent and the flight attendant could see that I was in distress and brought me some face masks

Airplane was cold. Flight attendants were rude. Phone charger did not work. No food available.

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

No explanation of why there was no snack and drink service (unless requested) when there was service in the other direction.

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.

Late and next flight even later. Who leaves at 245 am and arrives at 330 am ? No wifi, 4 hr flight and one bag of pretzels? AA should be ashamed

Horrible. I checked out myself that it seems that I can have a free carry-on. But they ask me to pay $75 when we are nearly boarding. It was tricky during check out that make you mistake that you can have a carry-on beside your personal item. Also they ask $75 in the airport instead of $35 during checkout. So the whole process is designed to make you this mistake

The cancelation of my flight from Toronto to Edmonton without any solution given to me for my next flight. Very poor connection from Toronto to Edmonton

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.

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

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

Excellent and a surprise as I had never heard of it before.

Those flights were operated by Delta Airlines.. one of the reasons I booked them thru Expedia, even if the tickets are sold by WestJet. Service on board is good with Delta, but don't expect much snacks on inland flights in the US or to Canada. Their entertainment system was modernized, but not much new movies in the catalog.. Free Wi-Fi for Skymiles member aboard.

Loved everything, especially during check in, very amazing people, they were so patient with me cos my bag was overweight. Loved their service. I’ll be using them again.

As per usual, lately, the flight was delayed. I can’t recall the last time a WestJet flight was on time.

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.

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.

during a very rough flight, I was forced to sit in a last row seat, fell asleep, and was forced to return to my assigned seat after the turbulence. The stewardess then used that seat to sleep.

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.

It was a short flight and for that reason the flight was acceptable.

Plane was old, cabin was small, overhead bins were small, seats really uncomfortable, no seat-back entertainment

Overcharged by either United or Air Canada. Abuse of access to my credit/debit card.

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

The flight was terribly cold with no blankets available, not even any to purchase. They charge you for earphones and for food though they provide pretzels or a cookie with refreshments. The seat was very thin and generally uncomfortable. I would not use them again though the crew were very nice.

It got to my destination on time. However I don't want to fly Air Canada again. The seat I reserved when I booked was somehow lost by the time of checkin. I specifically purchased a window seat so I could see outside, but the flight attendants made me close my window the whole flight (even during normal daylight hours over Canada), which was disappointing and also made my jet lag worse. Also there were no vegetarian meal options.

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

Do something about that crying baby the whole flight. lol

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

It was all a very positive experience. Look forward to the return trip.

Flight was great (only a short hop from London to Dublin). Wi-Fi available on board(around 2 euros), power sockets, complimentary water and biscuit. Landin/ takeoff all went without a flaw.

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 A350 is a great plane but BA's seating was incredibly tight (eg compared to the same plane as flown by BA's partner Finnair) and with a middle seat it was very claustrophobic

Free food and drink! Got a late start due to mechanical problems w a luggage loader.

British Airways canceled my flight and I had to fly on Lufthansa the next day. What a garbage airline 🗑️

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

The mushroom rigatoni was very flavorful & made me happy. The flight team was accommodating and friendly & I look forward to using BA again in the future.

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.

The crew will not help you with the overhead bin even if you are business class. If they do, there's always the sentence " we are not supposed to lift anything".... To charge for seat assignment in business class is nothing short of money grabbing/ ripoff. The ground service in London is better than Vancouver, which was atrocious.
