Insights shared by verified travellers who flew the route from Dublin to the United States 
Verified travelerFlew with Aer Lingus-Sept 2026
Get there early enough to be able to relax and shop a bit
Verified travelerFlew with American Airlines-Sept 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.
TysaFlew with Aer Lingus-Sept 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-Sept 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-Sept 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-Sept 2024
You need almost 2 hours to be sure you will clear US pre clearance
Verified travelerFlew with Aer Lingus-Sept 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.

The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

The flight itself was fine, food was expired and gross, staff were mostly amazing! KLM messed up rebooking for our first two flights that got cancelled and we almost didn’t make it to Amsterdam for an additional two days

I think I previously submitted my feedback about flight lead Katherine in a different field by mistake. Please see those comments. Comments for Hyd to AMS are it was good. The flight lead and service met expectations for satisfactory high quality service but the flight lead did not stand out as exceptional as did the leads on the other two flights so I don’t remember anything specific one way or the other besides the fact I was satisfied.

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,

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

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

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Good flight, even though there was a delay, still got back on time

Santa Barbara is a super small and easy airport. Breezed through rental car return, breezed through Security, ordered a coffee and muffin and to my gate in less than 30 minutes. Maybe because it was a small airport we got the oldest plane. Hardly any overhead space and absolutely zero internet. Its NFL Sunday man! That hurt.

We were delay because so many bags needed to be gate checked and it was disappointing not to have outlets in the seats for such a long flight.

There were no vegan options for first class. Even though we were promised the satellite internet for free, we received NO wifi at all. Even though we were promised a 20-min early arrival, we ended up over 30 mins late.

No water or beverage was provided. I had to ask for water. The sole flight attendant had more interest in selling the credit card. In addition when we got to Dulles the plane and gate were misaligned and it took at least 15 minutes to get off the plane.

Raleigh to Chicago was OK. The problem was Chicago to Lincoln. Flight was delayed 4 hours. Give them credit for the updates and reason why it was delayed

Flight delayed over an hour with plane on runway because of weather in an area of the country we were not in or flying to.

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.

Didn’t have requested food and seats could be more comfortable.

Flight attendants on this flight were very lovely. Hot food was terrible. Canned wine felt elevated and was GOOD. The aircraft was overall not very clean. Although this one was much more cleanly than the flight from Pisa. Pilots were great & landings felt smooth and safe. As I mentioned in my last review, this was my first time flying aer Lingus in many years and I cannot say I will be rushing to book again. This airline needs a real facelift.

Everything went extremely smoothly! They boarded by groupings of seat numbers starting from back to front. All staff very helpful and accommodating. Food and beverage plentiful and good.

The plane from Venice to Dublin ran out of food. They did not restock the plane in Venice.

It was very refreshing being in a nice and clean plain, with pillows and earphones that you don’t have to pay for, with warm food and beverages and a very nice crew

The thing thy call a pizza was atrocious. Do not eat it. The seating is as usual for economy an experiment in cruel and unusual punishment that they aren't allowed to do to prisoners but you get to pay for it.

Didn't make it to this flight as we sat on the tarmac for 1.5 hours.

The crew was first rate. They allowed me to switch my middle seat to an isle seat and it made my flight home so much more comfortable.

Everything went very smoothly I loved having the earphones and the blanket and the staff was just super friendly

I was advertised a free seat selection for a "Smart" fare through BusinessClass.com. I was never able to select a seat. I thus paid extra for a bill of goods I was never provided. would love to speak with a representative of Kayak

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.

Over 3 hours and 25 mins delay, entertainment screen froze on me for more than half the flight

they couldn’t not serve coffee or tea as the water that was boarded was not potable. the veggie food was lousy. tasted very sweet. there was a crying kid a few rows ahead. what about the difficulty caused to other passengers because the kid was crying so much. parents should know their kids better and not travel. it was a very difficult situation. would not recommend this airline next time.

the internet connection was poor. and the change of time

Horrible, they detoured my first flight to Roswell and the communication on why was very poor, We arrive late then waited 20 minutes for them to set up the bridge. I arrived at my connecting flight gate and was told my seat had been given to someone else even though the flight was delayed. We then get to customer service and the computer went down for several hours. The person at the counter was eating their lunch while trying to help me get a flight. Dhe then rebooked on a flight with a connection that was leaving two hours prior to me landing. So I had to then stand in another line to get rebooked. I missed my trip to Morroco and waited 7 days to finally get my luggage. It was a nightmare.

Based upon our entire experience with Iberia, we will never fly the airline nor recommend the airline to anyone. The flight to LA was fine and the crew on this one flight was god, but Iberia treats its customers (us) horribly. There was not one flight on this trip that they did not treat us poorly. We were bumped, lost seats, lost luggage etc all on flights we booked over a year in advance. Not one leg with Iberia went smoothly. And now they have lost our luggage somewhere in Madrid. This is a horrible airline. A truly horrible airline. And Underpricer recommended by Kayak is horrible as well. The lesson learned is to book directly with an airline and stay away from Iberia at all costs.

Very cheap airline, not worth the price. And they almost lost my luggage at JFK during a direct flight. I can't believe I paid that much money for a horrible 'premium economy' flight. Just fly economy on the cheapest end; premium economy is no different. Very very poor.

There was confusion over the electric wheelchair. Though it was categorized and double checked at checking the gate seemed confused by the chair.

Boarded in group three at Barcelona, which meant going from a gate outside onto a bus to ride across the airport to a plane waiting on the tarmac. When we arrived at the plane, crew behavior told us something was wrong. Bus driver would not let us off for almost twenty minutes, despite being crammed shoulder to shoulder. Eventually, we got onto the plane, but were then told that someone “forgot” to refuel the plane and the truck to do so had not arrived. We departed late enough that we missed our connecting train in NYC, which was the last train of the evening, so we had to stay awake all night in the passenger waiting area of Amtrak’s Penn Station, which was almost impossible to get to because the station was now closing, as it was after midnight. We had to haul four suitcases a few blocks on city streets in the rain to get to the one remaining open entrance to Penn Station. We ended up being up for 36 hours straight because someone couldn’t do their job. Never, ever again would I fly this airline.

Flight was delayed by well over an hour. Communication was terrible.

How to get an aisle seat without paying extra? The young lady next to me was assigned the seat.
