Flights from Ireland to the United States: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Ireland to the United States 
EDFlew with American Airlines-Jul 2026
Expect a bad cushion to sit on so maybe buy something to sit on. Bring food because although you get food it’s not that good. Hopefully you’re not delayed because no one will tell you why and you won’t know until the day of
Verified travelerFlew with Aer Lingus-Apr 2026
If continuing from LAX on SkyWest, be prepared for a long walk followed by a bus transfer, and get your necessities before you leave the main terminal areas.
JimFlew with Aer Lingus-Mar 2026
The A330 is very loud in the back; better to book a forward seat.
JohannaFlew with Aer Lingus-Feb 2026
Are Ling’s was great, and boards from the back of the plane, which made boarding way less chaotic and much quicker.

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

I am ina wheelchair and the gate agent knew exactly what to do when boarding just the the one of the flight attendants

There is consistently no communication/updated time slots in the app on when a flight will board when its delayed, which is the most frustrating as a consumer trying to understand if they need to get food now, or if there is actually a chance for them to eat during their layover. This keeps being my experience with delta and a potential reason to change airlines.

Long delays at both DCA and MSP; Crew did not keep us informed (or very little). Airplane was showing signs of heavy use (not up to Delta standards). Food options for Business Class have dropped in quality. After landing we sat on tarmac for maybe 25 minutes with no provided chance to use the bathroom and crew did not tell us what was going on or give an estimated time to expect to be at a gate.

Both of my flights to and from JFK experienced significant delays. Most notably, my first flight was delayed by six hours due to crew members being affected by delays on a previous flight. While I understand that disruptions can occur, Delta’s staffing and operational planning should include sufficient contingency measures to handle situations like this rather than placing the full burden of those delays on customers. Additionally, the $12 meal voucher offered as compensation was inadequate, particularly given the high cost of food and beverages at the airport. Considering the length of the delay and the substantial inconvenience caused, I believe more meaningful compensation would have been appropriate.

Although I know the Airlines cannot control the situation when there’s a ground stoppage, it would’ve been nicer if we would have had more up-to-date information clarity around the delays. Additionally, I think the delays also took a toll on the Cabin crew, particularly the lead flight attendant in first class. She was not very friendly when we boarded the plane for many of the passengers. Number one she refused to hang a garment bag in the front closet for a first class passenger, she was unwilling to dispose of an empty bottle in the trash as I was boarding (despite drinking a bottle of water herself and needing to disregard), and she was very combative with a passenger, who needed to access something from his bag that was Gate checked. Frankly, it was really unfortunate as I’ve never seen a flight attendant behave that way directly to the passengers, particularly when none of us had done anything wrong.

overall the crew onboarding and providing service during our flight was great; they were friendly and helpful. I said ok to the entertainment because there was none, but the crew explained why which was very helpful. I am a diabetic and the type of snacks are not diabetic friendly (full of carbs and sugar). However, I am always prepared because I know the catering is for the larger population.

The internet was spotty and I was unable to watch any movies on my iPad; the flight was fine otherwise

While it wasn't the crew's fault, it was a frustrating flight. We sat on the runway for 2+ hours. Both of the flight attendants were excellent and did a great job checking on the passengers. The pilot did keep us informed about the wait. I appreciate the crew apologizing for LaGuardia airport's backup.

The food was good. I ate gnocchi with marinara sauce and cheese, salted caramel tiramisu. And later in the trip cheese calzone. I watched 3 movies. The selection is really good. Have new and old movies. The flight attendances were nice and cordially. Overall the 6 hours trip was really pleasant ☺️. Planning the next trip.

The website check in was poor. Baggage fees were in US dollars but registered in Canadian dollars. The site would not accept my credit card. Scanning the passport was the worst. Someone from United needs to try the process. I’m not a novice with tech and I have to say this was a bad experience. Everything else was great.

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

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.

Seats are complete BS for 10 hrs. The guy at counter canceled our return flight from europe. Lufthansa on the way back made United look like a trailer park gathering. If given the opportunity, I will never fly united again. Lufthansa seats werent much better to be fair but the service was a 10 out of 10. Incant express how difficult umited made my trip.

Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.

The flight to America was freezing. The overnight flight back to the UK was boiling hot and the cabin stank of toilet or occasionally perfume, even though I was several rows back from either bathroom. Food was tiny portions. Two small pieces of tough and dry beef in random gravy with pretend mashed potato raking up most of it. Very little veg. Salad was ok. Wooden cutlery broke within minutes of using. Lots of old films for entertainment. Some new ones. Generally a bit rubbish.

It was a good experience, unfortunately my checked baggages were come late and not arrived on time.

The flight was canceled the day of the flight. United says it was FAA issue, with some 35 flights canceled and more delayed.

Slight delay but not bad. UA app worked well! Got regular updates of gate changes, etc. Don't have any complaints.

If other people in flight, followed instructions and were much cleaner.

Very comfortable flight. Great service, food options, and entertainment options. With Wi-Fi!

On time departure and arrival at LAX - good inflight entertainment - all basic seats on every airline right now begin to feel small after 10 hours!!

I was pleasantly surprised. I've never flown this airline and the seats were comfy, I couldn't select my seat but luckily got aisle and was able to comfortably sleep the whole trip except when they came around with an in flight free meal, drinks then snack at the end. I'd fly with Aer Lingus again. The only annoying thing is you had to pay for WiFi for different hours of usage but luckily I didn't need it

This was a great flight. I love the way they had general boarding board from the back first by seat row and in general the flight was very comfortable. The seats were actually comfy, and the food served was surprisingly good.

A seat was broken There was a delay of 45min A checked bag was missing in Boston

The service was some of the worst I have experienced on an international flight. The service was rude, the quality of the food was very low. The speed of service was insanely quick. You couldn’t finish your pretzels before the meal came before the coffee came before trash collection came. Then they never came back for 5 hours. They rushed everything so they could get it over with.

A special shout-out to one of the check-in staff at DUB yesterday noon. We had to use the "Closing Flights" counter and we met, hands down, the most efficient person - able to resolve several issues in the matter of minutes, while remaining polite and calming everyone down. Great job, Aer Lingus!

Everything was great!! I had no problems!! I would fly Aer Lingus again! 🥰

From Rome to Dublin if you want any refreshments you have to pay for them, Not used to this as we typically get soft drinks and a little snack on a 3hour flight in the US.

Boarding was fine, difficult to understand the guy over the speaker though so we were unsure when exactly to board until they updated the monitor by the gate. Flight itself was fine, nice flight attendants, seats were comfortable enough, good selection of entertainment on the screens. Other airlines at a similar price point have included wifi though, at a minimum messaging, for free, so that was a little disappointing to not have that. But otherwise fine. Food was pretty decent, nice hot meal, good drink selection, nice snacks. Bathrooms were ok, could've been cleaned a little more often, but they were never bad.

American airlines is always delayed in their flights. No access to wifi unless paid

Pilot main message was to "be nice to her crew". Crew only instructed passenger to "move out of the aisles" rather than helping passengers place their luggage. Some passengers needed to exit early to make their connections yet cleaning crews rushed onboard to make their way past rushing outgoing passengers. AA needs better protocols and better customer service for the price paid for trips.

More options on TV shows and movies and make it where if someone wants to choose their seats that it is an easy process. I wanted to choose our seats and never could do that! I even called and they told me I had to do it with agent at the airport. That was very inconvenient

We were treated politely and the crew was nice. Again no one knew why there was a delay. Food was hot and a lot was offered but bad in taste. Seats weren’t the worst but for a long flight your legs ache from it. Entertainment was old not very interactive

I had a comfortable and enjoyable experience. The entertainment options were plentiful, the food was appetizing, the snacks were tasty, and the staff was friendly, professional, and helpful.

This was my first flight on Aer Lingus and it was great. The plane wasn't full so I could move to a seat with extra room. The food was pretty good for airline food and the staff was nice and attentive. I enjoyed the media provided during my 10 hour flight. We arrived home early and it's always good to be home!

WiFi didn’t work for me. as headphones didn’t work either.

Canceled flight for unknown reason after numerous delays and only available flight was the following day yet no compensation. No weather problem. Then had to fill out form to get refund. American used to be a quality airline - no more, very sad!

entertainment choice was excellent for both movies and audio. Food was quite good. Staff was excellent and flight was on time and smooth.

The flight was uneventful, which is always good. The plane was clean and seem to have a little bit more room. They fed us every couple hours, and we had a lot of in-flight entertainment. The staff was very helpful and attentive.

JetBlue cancelled the flight along with hundreds of others, for no apparent reason. no recourse, no rebooking options. never booking with them again

Jet Blue cancelled my flight after I had boarded. They attempted to rebook me for a new flight two days later. I was able to rebook with a different airline, but not until the next morning. As such, I was forced to get an expensive hotel and missed important work meetings Monday morning. I am very disappointed with the customer service and will be pursuing full reimbursement for my hotel cost.

You did a great job rescheduling my cancelled flight. However, you made me pay for two seats for $118 even though the seats on the original flight were free. I think that was a very unfair thing to do.

They cancelled the flight after 5 hours at the airport and the only flight they offered was for the next day with a 7.5 layover in fll. This was not going to work for me as this was only a weekend trip and getting into providence at 10 pm a day later caused me to lose Mo ey on hotels money on airport parking a dog sitter etc. they wouldn’t offer any type of a voucher or anything else. All they did was refund the flight which didn’t help me with all the money in time I lost. I was going to see my very sick father

The plane took off very late upon arrival and departure

The flight was on time the crew was courteous that makes for a good flight.

A more comfortable seat. Padding would be really helpful but I've read the airlines don't want customers to be satisfied with economy seats.

Everything was good except checking bags . I had paid for two bags but it didn’t show so we had to do it again while people waited and we were struggling to get to our flight

Flight was delayed. But my finances flight with JetBlue a week before same route was extra delayed and then cancelled at 2am when his flight was suppose to take off at 7pm was never provided a hotel or anything. Came back to airport and his rescheduled flight was cancelled again for 2 days later. Was told since it was a weather issue they don’t do refunds. But that’s a lie because I booked him on another airline at the same time and they were able to take off perfectly fine

Flight delayed 4 times on a non-stop from BOS to SFO. Then when landed in SFO had to wait for 30 mins for a gate AT 3:30AM.
