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

Insights shared by verified travelers who flew the route from Dublin to the United States 
MichelleFlew with Aer Lingus-Oct 2026
Get to the airport a bit early to complete the customs pre-clearance for the USA. It's nice that you can do it, but getting there is a bit of a maze.
Verified travelerFlew with Aer Lingus-Sep 2026
Get there early enough to be able to relax and shop a bit
Verified travelerFlew with American Airlines-Sep 2026
Arrive at least 2.5 hours for check-in. Check-in line was very long at 1030. Waited 45 minutes to check in. There is a pre-clearance check after security in Dublin, so that you don't have to go through customs in SFO. Apparently this saves a lot of time because the pre-clearance check is much faster than customs. Pre-clearance check just ask you what food items you are bringing home. Plane landed in Terminal 1 which is usually for certain domestic flights because no need to go through customs.
Verified travelerFlew with Aer Lingus-Oct 2026
Terminal 7 at JFK is very poorly signed, and even if you're already booked through on a connection, you will have to leave the airside to change terminals. Since customs and immigration are handled in Dublin, a word of caution that there are limited duty free and food options after you go through customs in Dublin.
TysaFlew with Aer Lingus-Sep 2026
Again if you can check in in advance online if you have checked baggage otherwise the counter can take a long time if priorities the only one open so show up early enough to accommodate that
Verified travelerFlew with Aer Lingus-Sep 2026
Customs done in Dublin and security can be busy so go early.
Verified travelerFlew with Aer Lingus-Jun 2026
Make sure to tell your taxi driver the terminal you are flying out of from Dublin. My taxi driver only asked me what airline and apparently there are more than one terminal for Aer Lingus. Also go extra early when flying to the US because you go through customs while in Dublin and do not have to do it when you land in the US. As far as Aer Lingus they were amazing!!!
Verified travelerFlew with Aer Lingus-Jun 2026
Was happy we did have allowance for 1 carry on and 1 checked bag per person. Ensure the airline you select has access to WiFi and entertainment cause it’s a long flight!
Verified travelerFlew with Aer Lingus-Jul 2026
I have only flown Aer Lingus from DUB to the states. It's a call that doesn't disappoint. Be aware that bag drop-off and check-in counters at Terminal 2 close 75 min before the flight, and you have to undergo extra security when flying to the US.
MaxeyFlew with American Airlines-Aug 2026
Compare American with Delta and United. Be prepared to allow for extra time to pass through U.S. customs in Dublin. The upside is that you walk straight into the terminal at DFW, and don't have to do customs there.
KirraFlew with Aer Lingus-Jul 2026
Grab any food or snacks before going through the US preclearance. There are a few vending machines and a restaurant after but its very limited selection.
Verified travelerFlew with Aer Lingus-Aug 2026
Multiple security checks and immigration at Dublin airport so even 2-3 hours of layove is short.
Verified travelerFlew with Aer Lingus-Aug 2026
Get to Dublin airprort early due to extra inspection and security clearance for US bound flights
Verified travelerFlew with Aer Lingus-Jun 2026
Come to airport early when leaving from Dublin
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.
ShengFlew with Aer Lingus-Jan 2026
Aer Lingus agent booked us a 1-stop reservation via Air Canada to replace our original 2nd leg flight to LAX. I was surprised to discover the new trip only has the 2nd part in the Air Canada system, 1 day before the departure time. I spoke to the ticketing agent again, who really made her efforts to confirm a new reservation for our big group of travelers. I was not happy about the surprise, which can be of a very rare situation, while at the same time I do appreciate the agent's effort to help us get back home ASAP. Lesson learned: even with a printed itinerary, you still need to double check on the carrier website to be sure.
Verified travelerFlew with Aer Lingus-Dec 2025
Dublin Airport has US Preclearance, meaning you go through US Customs and Immigration before boarding your flight. If you're connecting through Dublin, this can catch you off guard. You'll need to clear passport control twice between gates, so plan extra time for short layovers.
TimFlew with Aer Lingus-Jul 2025
Check your bags if traveling to the US if included / possible. It was a long walk for the flight connection and we did US customs and immigration in Dublin, not Boston, which was a first for us.
MichelleFlew with Aer Lingus-May 2025
Make sure you arrive well ahead of the flight. We were lucky that security lines were pretty short but they could be very long and you do US customs and security in Dublin.
YaneliFlew with Aer Lingus-Apr 2025
Arrive early (3 hours) because lunes get very busy.
Verified travelerFlew with Iberia-Sep 2024
Taking the coach bus to Dublin from Castlebar to departures was affordable and easy.
NinaFlew with Aer Lingus-Nov 2024
Make sure you include extra time to pass through US Border Control if you’re flying to the US! Also Aer Lingus bag drop closes 75 mins before flight departure for long haul so bear that in mind!
ConnerFlew with Aer Lingus-Sep 2024
You need almost 2 hours to be sure you will clear US pre clearance
Verified travelerFlew with Aer Lingus-Sep 2024
Allow a full 2 hours for check-in and boarding.
Verified travelerFlew with Lufthansa-Aug 2024
Give yourself enough time to go through US Customs in Dublin.

Great overall experience and use of the Delta One lounge was amazing!

I used by Skymiles to upgrade to First so that I could comfortably work using my laptop. But WiFi was intermittent and unavailable for long periods. I feel like I wasted 70,000 miles :(

Great as one can be for a one connection 6 hour flight

The gate attendant was not clear w message on flight delays.

Chairs don’t recline and the ones that do recline, barely do recline. It was most uncomfortable flight i ever been on.

Good service but not on par when compared to foreign flag carriers.

Travelling with 2 others for work. Delta asked to check their carry ons due to the fullness of the plane. This was all good until the next leg of the flight. One of the 3 had their carry on checked through to the final destination but their passport on in their checked bag. Which they could not get to and he was not allowed on to the plane. Even though Delta had to retrieve his bag, because he was not allowed on. So they got his bag and he was in the terminal, but even when the flight was delayed, due to mechanical issues, he was not allowed to come onto the plane. Since the delay was nearly 2 hours, he was finally allowed back on the plane.

good in general food is just snack and beverages (same snacks all the time) could you try to change them?

We experienced delays in small increments that added up to more than an hour. At the gate, staff showed little concern and compared our delay with the inbound flight’s two-hour tarmac wait, which didn’t address our situation. Once onboard, the flight attendants seemed tired and unfriendly. I understand delays are frustrating for everyone, but passengers shouldn’t feel blamed for them. During the flight, a bright light above the emergency exit stayed on. It was concerning, and no one explained it or offered passengers the option to move. After landing, we waited about 30 minutes on the tarmac for a gate, then waited again for an agent to connect the plane to the terminal. From the Reagan gate staff to the cabin crew and RDU personnel, the service felt dismissive throughout. Overall, this was a stressful trip and a very disappointing customer-service experience

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 staff on the flight were utterly brilliant; there was a young man who was particularly exceptional. Boarding was quick and seamless, and service was great! Seats were fab, as was the entertainment and its ease of access

i’m The staff on my flight were amazing as always, beautiful professional staff, they do amazing job. the food ? room for improvement

The agents at the boarding desk were not very helpful, however the hostesses on board the flight were great, the food was ok, and there were lots for choices for entertainment. I was stuck in an middle row seat which was a pain on a full flight, but otherwise the flight was great.

The man in front of me reclined the entire flight, including during meals, which was aggravating. My screen had issues with brightness and kept flickering in and out.

Still some confusion about my baggage which was disconcerting. It was nice that there was extra space on the flight for comfort reasons. Staff very friendly

Everything was smooth and the meal was delicious. I really appreciated that Aer Lingus still offers complimentary beverages, food, luggage and headphones. It was nice that the main meal also featured some items typical to Ireland including the wheaten bread and Kerrygold butter. I generally found the flight a quite relaxing and enjoyable experience.

The seats are so close that you have 0 room to move. Not acceptable for an 11 hour flight.

Easy process you definitely need 3 hours to get on board from Fuminchino airport

Amazing, not too crowded, great temp and the meal was good

The crew was good. The flight was not overly crowded so we had some additional space.

1 person checking us as we boarded, left gate on time, 12.30 we are told we were held for 15 mins as other flights were waiting to take off, captain due to rain … they were having a longer gap between take offs , 3pm we took off , they went land route via New Orleans in to Florida landed at 5.45pm offered coffee and a biscuit

Service was slow Flight was very loud at back of plane

There was no internet on the flight. As an executive flying during prime business hours, having internet is critical for a smooth experience. This impacted productivity and time that will need to be spent later to do the work I could have done on flight.

Terrible boarding - 4 flights boarded from the same gate. Chaos there; long ramps to the plane.

Comparing premium economy trips to other airlines United performs poorly in regard to food, service, bathroom cleanliness etc

They took us all the way to Monterrey to tell us they United were not allowed to land and we were sent back to Houston. Terrible experience.

Fine except from Chicago to moline three different gate changes and flight times

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.

I want much more comfortable seats on these aircraft thank you.

The boarding agent and checked bag agent were both rude. It only takes a second to be kind. However, the flight crew was amazing. I got a turkey sandwich and it wasn't bad---not great but not bad. The internet was my biggest problem. This was a work trip and I REALLY needed the internet to meet a deadline but it didn't work for 80% of the trip. Very disappointing.

I tried to check in beforehand from Ireland. The Jet Blue website sent me to the Aer Lingus website and vice versa. I tried to get a boarding pass at Dublin Airport as well, but they said they couldn't help me either. I had to wait until I arrived at the gate in Boston to secure a boarding pass...it was a bit nerve wracking.

Great flight. Best in years. Very clean craft. Easy boarding. Communicative pilot. Friendly flight attendants. Absolutely smooth take off, in flight and landing. Very comfortable seats. Smoothest flight I've experienced in years. THANK YOU JET BLUE!

I was asked to pony up an additional $239 (over the $735 paid originally) for a one way middle seat, which was very uncomfortable. Where did you expect me to sit?

Jet Blue sevice was good. Just don't understand why they charge for earphones to listen to flight entertainment. Other than that, everything was excellent.

The whole experience at the airport in Istanbul should be made known beforehand. Four passport checks and a huge check-in line as I could not check in online made it a very lengthy and frustrating experience. The flights on Turkish Airlines however were just fine.

Mostly good, flight take off in time and land earlier I can’t ask for more..

The crew was not nice this time. I asked for a drink one time and the girl didn’t say anything to me and just got me the hot drink while walking super fast to the back. We were sitting in the back and she wasn’t doing anything except socializing. She was upset I asked for something and she had to do her job. I also didn’t fully have it in my hands when she handed it to me so it was dangerous. She was abrupt and rude. She wouldn’t allow for people to spread out like previous flights we had been on if they were empty, and there were empty rows. It was strange and she enjoyed being angry at us.

The plane was FREEZING COLD. Like I was wishing I'd brought gloves. Is this how JetBlue sells more blankets? Other than that, all fine. Crew just as nice as usual. A flight attendant asked (who? The pilot?) to have the air turned down for a great number of passengers who were as cold as I was. They (again -- who is "they") did not.

I liked that 5 pound refreshment voucher was given for 1 hr delay. Staff were courteous and professional. I was expecting more for the 2nd meal (pizza). Usually for a long flight, the 2nd meal is something like eggs/sausage/potatoes/fruit/dessert.

The boarding process, airplane, entertainment, beverages and crew were very good. But the food left a lot to be desired, especially for business class. I had a chicken breast that was tough and rubbery, with little flavor. It wasn't even up to the proverbial "banquet chicken" standards. Very disappointing. There was only one offering of bread, OK, not a huge deal, but it's a nice touch to be offered more. Similarly, other airlines' crews come by to offer more drinks, though the crew responded when asked. Good flight overall, but the food just wasn't up to the standards you'd expect.

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.
