Insights shared by verified travelers who flew the route from Dublin to the United States 
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-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.

Delta was great because the flight was almost 5 hours so I had access to tons of movies news, etc. so it helped past the time by no other plane WestJet did not have movies so Delta was the best

Noting this only because it’s so unusual for delta: this was just an uncomfortable flight. The jet ridge was too hot and the plane wasn’t any better. By the time we got off the ground the AC was on but for such a short flight it was almost too late.

1) It was extremely hot in the cabin. All the passengers were sweating and it almost became suffocating 2) It was a 50 min flight but there was no service. How can a 50 minute flight not have any drink/snack service?

Very bad multiple confusion and miscommunication which i ended up missing my flight.

There was no food, so :( to that one. The flight was delayed by 3 hours. Not Delta's fault. Not the crew's fault. Considering how tired all us passengers were, everything went surprisingly well. The flight crew were very helpful, friendly, and professional. I always fly Delta.

Delta is a perfect partner, offering the gold standard across the board.

Our flight from Detroit to LaGuardia on Thursday 8/20 was delayed from 555 to 910 due to storms and a ground stop at LGA. It’s never fun to be stuck at the airport but I thought the desk crew and captain handled it well and kept us informed. I especially liked how they referred to us as their “LaGuardia family.” I am a loyal delta customer and this is one of the reasons why.

Terrible. Waited on runway for 1+ hour after landing and then was brought to wrong terminal

The flights were on time; all went as expected which is a big positive! No delays! There was no food or drink service in any legs, which I understand due to the short flight time.

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.

First time flying business class. Very comfortable for our long flight to Europe.

Not a United thing, but late afternoon departures from Denver with thunderstorms is always prone to delays.

Kayak booked this flight with only 1h 20min layover in Chicago. This made it impossible for me and several other passengers to reach this flight. Moreover, the gate closed boarding in spite of several passengers still on their way without waiting even one more minute. However, the plane departed with 20min (!) delay, i.e., there would have been at least 15 min time to let the delayed passengers board without causing any delays. I complained and as a "thank you" the attendent booked us on the last (!) flight to Indianapolis ~7h later! Thankfully, I caught the spitefulness and the United customer line rebooked the flight to an earlier flight. Although I can't grade this particular flight since I never had a chance to take it, Kayak made the mistake of a too short layover and the crew at the gate was awful.

Sitting in coach even in the larger leg space is extremely uncomfortable and the staff pay no attention.

Really delayed, no effort to support customers other than “sometimes we run late.”

It was serviceable, nothing special but nothing awful on this leg.

On boarding crew at the airport called in the boarding numbers too early meaning before the previous line was completed resulting in later numbers getting to board ahead. Also she asked those who boarded from number 3 to have the tags in their carry-on bags and leave it in the jet bridge. Most of the overhead bins were empty though. This is more work for the ground staff in addition to more inconvenience for passengers waiting to get their carry-ons from the jet bridge.

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.

We traveled with my 90 year old mother and she was well cared for by everyone from the wheelchair attendant to crew. Greatly appreciated!

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.

The flight was delayed by about an hour due to a maintenance issue which later then required a change of planes. The crew was great and friendly. The in-flight entertainment did not play properly on Apple Vision Pro in a Safari browser. Although the movie trailers would play fine, the actual movies themselves just had a black screen with audio. There must be something with copy protection or something that isn’t compatible with the Safari browser on Apple Vision Pro. The free inflight Wi-Fi for American Airlines Advantage members is a nice bonus. and is great that they aren’t charging extra for things that have become basic utilities in 2026, like internet access.

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 series of delays were very unfortunately - first the captain timed out, then the new captain didn't show up when we were told he would, then the first officer timed out. Those delays were compounded by after boarding, weather came in - obviously that's out of JB's control but it was frustrating after all of the other delays that seemed avoidable.

3 hours late JetBlue flight made me miss my connecting flight to Nairobi Kenya, they did not even offer me hotel accommodation, I paid out of my pocket, they did not know where my luggage was, let say my experience with JetBlue was nightmare.

JFK is the worst airport and JetBlue is the worst airline

Crew at first tried to SELL snack boxes (for an hour-long flight?!?), and it was the only leg of four on which I was charged for a hard seltzer. 😕 Spent extra to select seats in Row 8 for quicker disembarking only to be seated in Row 25. Someone owes me $38 for that!

From Edinburgh to Boston was pretty good, actually! From Boston to DCA? Not so much. More food offerings for those w/gluten issues please! I don’t do well w/wheat OR legumes so neither the pasta nor the lentils would have been good for me (or pleasant for those around me on a 6+ hour flight!). Staff on the Boston to DCA leg were brusque compared to those on the other 3 legs of my trip. Also, I paid $19/seat to select 2 seats on the Boston to DC leg and we didn’t get those Row 8 seats but were sat in ROW TWENTY-FIVE😕 Someone owes me $38!

My screen didn’t work, my seat didn’t recline, the flight attendant was rude and completely dismissive, the airplane was freezing, the seats are way old, slanted and uncomfortable. I payed for a full ticket and got a horrific experience, with a flight attendant who dismissed me even though I was calm respectful and polite.

Check in and passport control were seamless and efficient. Plenty of room in overhead bins. Our original seats were separate but crew at the gate put us together in finer seats. I also had left my phone on board and the Jet Blue staff were so helpful in retrieving it after I had left the baggage area

Very poor help no one answering a question regarding seating. Very rude staff. They don’t care, as if it’s not part of their job. Flight was delayed for no good reason and no apologies given.

It was my worse flying experience. It was my first time and last time flying with Jet Blue.

The wifi didn't work and I needed to do some work. This was a business trip.
