Flights to Ireland: the best tips from KAYAK users' own experiences

Insights shared by verified travelers who flew to Ireland 
DaveFlew with Aer Lingus-Sep 2026
The Dublin Airport has NO rail service, so if making a rail connection, solid plans need to be made beforehand about where to go and how to get there.
IsabellaFlew with United Airlines-Sep 2026
My only tip is to put a small bag underneath bc you won't have room for much else.
JonathonFlew with Aer Lingus-Jul 2026
Don’t sit on the inside seat during a lay flat flight. Don’t order the beef short ribs, they’re kinda fatty, and chewy.. Try all the whiskey.
Verified travelerFlew with Aer Lingus-Apr 2026
Make sure to double and triple check that the flight you book actually exists before going to the airport.
LisaFlew with Aer Lingus-Dec 2025
Look at Jet Blue and Delta. May be a bit more expensive but keep an eye out for fare reductions and book early.
Mary MargaretFlew with Aer Lingus-Jun 2025
Some people may be required to check their carryon bags, depending on flight, plane size, check-in crew, etc. Also, taller people should purchase aisle seats.
Verified travelerFlew with Aer Lingus-Jul 2025
Whatever airline you choose, spring for a class with more leg and overall body room than economy (or whatever the cheapest class is called).
himanshuFlew with Aer Lingus-Jun 2025
Eat and drink before boarding. Snacks. Hand gel and surface wipes . Don't expect a window if in a window row.
BarbaraFlew with Aer Lingus-May 2024
Pack what you need in a carryon since it is likely you'll arrive without luggage.

The WiFi on the plane was out. I also thought movie options were lacking.

The WiFi on the plane was out. I also thought movie options were lacking.

They changed my seat assignment from window to middle. I have a physical need to sit by the window because of spinal issues. I unboarded in pain, I also was placed between 2 very large men. I am very disappointed and now dealing with the physical aftermath.

These Delta 717 jets are ancient. No entertainment and you have to pay for WiFi that barely works and goes in and out the whole flight. Delta should be ashamed flying this garbage.

The crew were awesome and ready to help as much as possible. The gate agent in Atlanta was tremendously helpful. The delays were ridiculous. Getting home at 4am when I could have driven home faster was unimpressive. Being delayed for countless hours through the night wasn't a great travel experience.

The staff and crew were wonderful. The delays were atrocious. The missed connections problematic. Getting home at 4am and having to go to work at 8 am, not a great situation. The gate agent in Huntsville was amazing. She helped everyone efficiently and with excellent problem solving skills. Her communication was helpful, timely, and thoughtful.

My seat was changed without my consent. It wasn’t a major deal but annoying.

Great quik boarding, friendly gate agent and crew. Let early

I somehow thought my food preferences was saved to my account— everything had dairy and couldn’t eat anything.

Breakfast before landing was a reheated breakfast “calzone” which was not good, at all. Otherwise, food was good. Crew not very attentive for taking trash from passengers being a little slow in eating.

Surprisingly the coffee was pretty good and they had a gluten free bar handy!

The united employees at the gate treated me very rudely and called me nefarious

The food was horrible. There was no. Wifi, and it was just terrible from bangkok to d. C

My flight got cancelled. Couldn’t get my luggage. It arrived at my destination ahead of me. I didn’t get my preordered meal. Had to spend the night in the airport.

The crew was good, the WiFi was amazing, but the plane was meh. Uncomfortable first class, not enough room for baggage. My stuff ended up being behind my seat, so I had to sit on the plane for 20 minutes before I could get to it after landing.

food /beverage service was limited to one time which was unexpected for a flight that long. food wasn't very good.

United did nit provide any updated on flight crew not bein available until boarding time started. It was bad. Itws alate night flight and there no proactive communication and iha d an important meeting that i missed due to thus

I initially boarded in a very comfortable and large plane and was told there was a mechanical issue with a waste receptacle. We sat on the plan for a good few hours, then were told we can deplane and that we would take off shortly. Delays continued and four hours later my flight was cancelled, and I had to quickly rebook another. The flight I rebooked was also delayed, and I when we boarded, I wound up on a small plane in a middle seat for the 6-hour journey and it was extremely uncomfortable. No issues with the staff in any way, just the overall experience of the delays, cancellations, and downgrade in comfort on such a long flight. It is significantly impactful on how you feel post travel and I was exhausted and sore from the experience.

It was pretty good, they give a small blanket, neck pillow and earphones. The only bad thing was not big enough leg room for your bag and feet. They gave us a snack, dinner, and breakfast on flight and food was good considering it was on a plane

I bought this ticket for my daughter. She had to pay for her carry on bag to be checked. My understanding is that transatlantic flights included carry on and personal item The nickeling and diming fo legacy carriers has stooped to an all time low. So sad.

The Economy Plus rows weren’t as roomy as expected, and the meal service left a lot to be desired for.

Absolutely the worst at baggage handling. Our baggage still has not been delivered. They couldn't find it in Dublin then when we got to Edinburgh they said the 2 bags were sitting in Dublin. After spending an hour filling out forms at the counter. We left for our hotel, bags arrived in Edinburgh at 505pm using my satellite tracker. Tried calling the numbers provided, no answer to their 24/7 service. Next morning the bags are still sitting at airport, no movement. Called different number provided by hotel in Sterling, the said it's souly the responsibility of the courier service now and they couldn't help. Completely ruined our travel plans, we must find clothes to purchase today instead of going to the museums we had purchased tickets for. This loss is costing us thousands in already paid hotels and services. No one takes any responsibility. I'll be contacting legal services on our return. We will never forget and I'll be a social advocate to avoid using this service.

I was disappointed with my experience on my Aer Lingus flight from Denver to Dublin. One of the biggest issues for me was the attitude of the cabin crew. They came across as cold, unfriendly, and unapproachable. There was very little warmth or friendliness, and I rarely saw anyone smile. I did not feel that the crew made passengers feel welcomed or cared for, which makes a significant difference on a long international flight. The cabin was also extremely cold and uncomfortable. What made this more frustrating was that we were instructed to put everything, including our blankets, underneath the seats at certain times rather than being allowed to keep ourselves covered. Considering how cold the cabin was, this was particularly uncomfortable. I also did not appreciate the tone used when giving some of these instructions. At times, the communication came across as unnecessarily loud and abrupt rather than polite and courteous. I understand that cabin crew have important safety responsibilities and passengers need to follow instructions, but those instructions can still be delivered in a professional, respectful, and friendly manner. Unfortunately, the lack of warmth and hospitality from the crew was the most disappointing part of my Aer Lingus experience.

Cabin crew was one of the worst in memory. Poor in delivering service - in some cases skipping it altogether. Someone in baggage handling managed to steal my electronic bag tracker from Apple.

I buy ticket from you and when I go to the airport aer Lingus they tell me you need travel visa for Ireland for one hour travel so when I buy tickets there no requirement I need transit, visa or not so when I try to cancel my ticket or change my ticket, you guys say there is no refund so you u guys take all my money which is very disappointed

The aircraft was clean and relatively comfortable- for an aircraft seat. The entertainment was good. The food was terrible, especially the “breakfast “ which was a cereal bar, and just not good. The crew were amazing, professional and no complaints there. The food was so bad, I know for my return, it will be inedible.

Awful customer service. What you are told 100% depends on who you talk to.

I love flying with them, the long-haul was fantastic. The short flight from Dublin --> Switzerland was horrible though. Most narrow seats I ever had, first and only time in my life I couldn't even close the seatbelt in seat 1A which was very embarrassing so I had to sit in the middle, because that seatbeld was 20cm longer. No idea why seat 1A would have a much shorter belt, it's just ridicilous. Also I hate the fixed seats, way too narrow.

Food was mediocre, but as expected in economy class on an airline. Wrap was ice cold , my son’s served by a steward on the next aisle was warm . As expected, but at least heat the food up a bit. No frills, but it’s economy. Excellent free WiFi was a bonus

I flew Aer Lingus Business class for the first time. Having flown economy a few times, I was familiar with the airline, and happy enough with economy. I’ve certainly been in nicer economy airlines before, but Aer Lingus is usually very reasonable, and I find the staff to be kind and have an Irish sense of humor and accommodation. The business experience was good, in that you got superior service to the back, lay down seats, better food and drinks, and more attentive service. However, the plane was a bit older, the WiFi was slow(not Starlink) and the pods were too close to one another for privacy, or function. When the Oder lady to the left of me fell asleep(fully reclined) there was no way for me to escape without having to wake her and put her seat all the way up. That lead to me being stuck with luggage I couldn’t put away in a cramped(for business) space, and no way to use the restroom for almost the whole 8 1/2 hour trip. I ended up trying to sleep with a large backpack blocking my feet. The food was good for plane food, but not great. The drinks were great, shame I couldn’t have had more, but I’d have peed myself. I love a window, but next time maybe an isle seat. Overall, the experience was good, not great, but an expensive good experience during which I got zero sleep. I’d do it again, but it’d have to be a deal.

The direct flight was a superb idea; please continue. The seats were less than comfortable for such a long flight.

My sons tv wasn’t working and they didn’t give him a kids meal I have to request it prior and no one told me!!! Then the 2nd flight they split us up. My two year old can’t sit alone on the plane hello?????

What's not to like? Value?definitely. Every JetBlue member was extremely friendly on this flight. Very very nice new-ish aircraft,plenty of room. GOOD coffee. Entertainment,I didn't need it,but I think its available. What to do better? Well,there's nothing we can do about the other people, unbelievable how some folks are operating. Just don't allow people to lug all their stuff onto the aircraft. 1 bag. That's it. Be easier for you too. I personally would enjoy more options in schedule. One flight in and out a day is warranted given the local,I understand, but the times are inconvenient. Again, I completely understand why it is that way,It would however be great to have different options.

Had to wait over an hour in line for a Jet Blue agent to appear at the the counter. Ended up a customer service agent from another airline lines helped to check us in, and boarding pass,

Thought the economy premium experience would match that of the Amsterdam to Boston flight. Aircraft was older: chair didn’t lean back. I had to buy a blanket, which on the flight over was complimentary. Flight crew seemed disinterested all around.

I propose enhancing the legroom across the entire cabin seating area and expanding the snack selection. The airline companies should prioritize customer needs over the extravagant and unjustified salaries of upper management.

KUDOS TO ALL THE CREW PROVIDING ASSISTANCE WITH PASSENGERS ON A WHEELCHAIR. ON BOTH FLIGHTS THEY HUSTLED TO TAKE MY RELATIVE TO CONNECTION ON TIME. THEY DESERVE A LOT OF CREDIT!

Good experience with this flight. Boarding was smooth with no issues. The short flight was good with quick drink & snack service. Nice easy way to get back from DC.

Very good flight that left on time and arrived earlier than anticipated, which was a plus! The crew members were very welcoming and helpful. However, the temperature on the flight was very cold - almost to the point of extreme discomfort. Additionally, requiring passengers to pay $8 for headphones to access the JetBlue entertainment was disappointing. Those earbud jacks are not used with most technology and would not be able to be used. There was no option to use Bluetooth for my own earbuds. Beyond those inconveniences, the flight was good.

My original flight was cancelled. My replacement flight was delayed over 2 hours. I lost my whole day in NY

Delays were crazy long (over an hour) both for boarding and baggage claim

Flight took additional prep time since plane came from Mexico, which resultrd in boarding and plane prep being delayed for additional cleaning procedures. Once boarded, plane tire was identified as being low on air and needed to be replaced, which creared the need to deboard and further delays for what was already a late night flight. Would have expected a better scheduled turn around and prep buffer that would have not created that degree of delay and deboarding

Very cold on board it was like having 16hours sitting in a fridge

My luggage was lost at some point during my layover between Chicago and LHR. I landed Tuesday morning, and did not get it until Thursday night. Ironically, the people at the ticket desk had added a “priority” sticker to my tracking tag.

The guy sitting in front of me kept pushing hard his sit against my legs… very uncomfortable

The customer representative that helped me when I checked in was horrible as she told me I couldn’t check my bag because I missed the 45minute rule by 2 minutes - because of the line at the counter My connection flight was delayed too

My experience was fine, with one surprising exception. After leveling off at cruising altitude, the main cabin flight attendant made an announcement that he had a cold, so he would not be coming through the aisle to provide cabin service. He claimed this was in consideration of his health and safety and ours. However, if passengers wanted a beverage, he invited them to come to the back of he plane, where he would provide service. I understand that a flight attendant's primary responsibility is to ensure passenger safety, but a secondary role is to provide service. If this flight attendant was too sick to perform his duties - and if he truly cared about passenger health and safety , as he claimed - he should have stayed home and called in sick, rather than exposing the cabin to his germs.

The flight was delayed multiple times. Breakfast was not served and only an apology given and statement that we could find better pastries in Paris. Seats were extremely narrow and uncomfortable.

Seats are very comfortable but WAY too small...i'm only 5'11" and 170 lbs but i barely fit in the chair! Food is just abysmal. I don't even bother eating. Staff were very professional, boarding was smooth, and plenty of room in overheads.

The economy seats are very cramped and the food was bizarre. However, I did like the greek yogurt option for breakfast.

horrible our connectig flight was late and we had to rush thru DFW to the next gate with 15 minutes time. Get to gate and its changed. no one knows whats going on . finally get a new gate and the plane has been sent back to the hanger . Boarded 4 hours after our original flight time and then sat at the gate for over an hour as the captian said the cargo doors were open and no one was in the airprot or on the ground to find out what was happening. this caused us to miss the first day of the tour as we missed our transfer and hotel meetup no apologies or accomodations offered to assist
