Flights from Dublin to California: the best tips from KAYAK users

Insights shared by verified travelers who flew the route from Dublin to California 
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.
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-Aug 2026
Get to Dublin airprort early due to extra inspection and security clearance for US bound flights
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.
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.
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.
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!

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

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

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!!

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.

On time, only a little turbulence, very competent and caring attendants. Clear information.

My issue is with the SkyWest terminal. The flight was not listed on the main airport flight screen list, and I had to do a Google search to locate the terminal and gate. We had to ask several airport employees where to locate the phantom gate. The airport did not provide adequate signage and was confusing. When we arrived, there was one vendor providing services that quickly closed, leaving zero options for food and drink while we waited hours for our delayed flight. The crew that assisted with check-in and boarding was VERY friendly.

No complimentary drinks or snacks offered on a 2 hour flight was disappointing but everything else went well

I love the direct flights. It saves a lot of hassle and allows immigration and customs in Ireland, making arrival much easier.

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

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.

Boarding was a mad rush as people still had issues with boarding passes and groups 3- 7 were asked to board when travelers were still stuck behind the document check. Food was one of the worst I’ve ever had in an Economy flight. The crew was very friendly though

It was extremely cold in the back of the plane. The seats are uncomfortable and space very small. Crew was excellent as usual.

Do Not Fly Iberia. Horrible experience. Iberia changes things at random -like the date of the flight and seat you have bought. After buying my flight, they contacted me and told me I had to return a day later. Then when I was boarding the flight, I discovered they had changed my window seat in a row away from the wing, to an aisle seat in front of the toilet! The worse seat on the plane. But it wasn’t just me- a family was scattered all over the plane. I was able to trade my seat because a father was separated from his son. Unfortunately the seat was the window seat directly over the wing, the loudest seat in the plane. I couldn’t sleep, even with noise cancelling earphones. Also, I ordered gluten free meal-which was tasteless and gave me cramps.

The flight was over two hours delayed. The aircraft was somewhat dated.

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.
