Insights shared by verified travellers who flew the route from Dublin to North America 
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
KatieFlew with Aer Lingus-Aug 2026
Have a long connection (5 hours) if you’re flying internationally
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-Aug 2026
Don’t travel from the us through Toronto if you are going overseas. The transfer took legitimately 2 1/2 hours and we probably walked 3 miles.
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

Friendly staff. It was extremely cold in the cabin. I've asked a crew member if they could increase the temperature but there was no change.

The required privilege for business class while boarding is not given. Food is average. The seats in business class are bad, worn out and dirty

It was really nice experience by flying this klm flight.I personally recommend everyone to please try this klm flight

It was really nice journey i personally recommend klm flight

Terrible last row seats many seats available but no offer to move to better seat

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.

Delay, luggage didn’t arrive. Had to go the next day to collect it

Booked connecting flights with KlM. My serving flight was the furthest part of the airport. On arrival in Zurich. My two cases arrived but only one carry on belong to my son. His three suitcase didn't arrive. After enquiring we discovered they were still in Amsterdam. We landed at 11.12. We eventually left the airport just after one.

The food quality is poor. The staff are very friendly and accommodating. The entertainment program was limited. I experienced a delay of 30 minutes due to two issues. Passenger luggage had to be removed and there was a technical issue with the stairs not detaching from the aircraft. The pilot managed to compensate and we arrived only 15 minutes later. The luggage at Dubai airport was very slow. I waited over an hour.

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

Very quick flight, efficient boarding, and clear and thorough instructions and attention from staff.

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.

First time flying airline. Great experience. Clean plane, comfortable seating, great service.

They lost my bag so that is unfortunate.. still waiting for it

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.

My flight was cancelled and United Airlines could not rebook or help. My whole trip was then cancelled and I could not go to the funeral I needed to get to.

Great, except the canon was so cold. Even the flight attendants put jackets on

Packed in plane small uncomfortable seats elbow to elbow nobody wants to be in that situation for the money they paid

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.

The plane was delayed ~ 40 minutes. Communication could have been better. The entertainment was poor. We were not offered headsets by the flight attendants. The arm rest pad did not work properly, thus, I could not select what I wanted to watch.

The service was non existent . Crew did very little didn’t even answer call button . Premium economy in this long haul was the worst I have ever experienced . Never again flying with them .

Nothing went smooth. From being threatened to pay $400 for omitting my middle name by agents in India or somewhere. In addition, I couldn't get an answer on how much a third bag would cost despite numerous calls to Lufthansa. Then I couldn't check in online because they wanted evidence of residency. I told them I have dual citizenship but that didn't help. Last but not least, my luggage didn't make it to my destination. I had Christmas presents that didn't get to family members on time. I also had to wait the entire day to have it delivered. I have never had such a bad experience with an airline. This is how you loose customers

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

I just stated the issue with the seat assignment in the previous post

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.

The flight from Madrid to Boston was awful. Without prior warning, I was seated in the row in front of an exit row where my seat did not recline. The person in front of me reclined, reducing my already tiny space further. This was the WORST flight I've ever had.

Not bad but they lost 2 of my bags when I got to Florence

Awful. They didn't even show concern that her connecting flight( Dallas to Mardrid) was gone/missing. I don't understand how that is even possible. Rudest answer from one of the crew was that American Airlines sold the tickets to somebody else. My daughter was not in the list.

It was budget airline Veuling, even though we booked Iberia.

Flight from Madrid to Dakar had no onboard entertainment for a business class. Not even a single screen . That was disappointing. The WiFi only worked for the first 45 mins of the flight.

Its a bus taking you on and off the plane so if you have big luggage … more muscles needed

The flight from Amsterdam to Dallas was great, ok food, good service, great entertainment. But Dallas to SF was very tiring because of two hour delay inside the airplane waiting for AA paper work in 99 degrees in the sun. We had no oxygen and the pilot had to ask everyone to blast the AC because it was getting too hot inside the cabin.

We had a seat that would not function. No Wifi or inflight entertainment was available. Food was very poor. Attendants were very accommodating and apologized for the problems.

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.
