Insights shared by verified travelers who flew to Ireland 
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.

It is also an excellent staging point for exploring the Aran Islands off the coast of County Galway.
  • Flying into Dublin Airport puts you in the nation’s capital and allows for exploration of County Wicklow, County Kildare and County Meath, whereas Cork Airport provides excellent access to County Cork, County Kerry and County Limerick.

One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

One of the restrooms didn’t work. The ones that did never got replenished. Flight attendant just sitting there on their phone. No notification that the bathroom was broken so long lines. Apathetic crew.

Pushing back flight and ultimately cancelling it after multiple changes and hours of delays. Comm were terrible as to what was going on and what options were available.

Even though we arrived early and checked in, for some unexplained reason, our bags were removed from the plane and put on the next flight. It took over 12 hours after arriving to get our bags.

Stewardess was not accommodating when I requested a second drink.

The morning calzone was less than impressive and we ended up with heartburn

Some of the passengers are coming on board with luggage so overstuffed and/or too large that have no business going into the overhead bins.

I am in a wheelchair The gate agent knew exactly how to boarding A wheelchair first also the flight attendant knew exactly what she was doing

There is consistently no communication/updated time slots in the app on when a flight will board when its delayed, which is the most frustrating as a consumer trying to understand if they need to get food now, or if there is actually a chance for them to eat during their layover. This keeps being my experience with delta and a potential reason to change airlines.

Long delays at both DCA and MSP; Crew did not keep us informed (or very little). Airplane was showing signs of heavy use (not up to Delta standards). Food options for Business Class have dropped in quality. After landing we sat on tarmac for maybe 25 minutes with no provided chance to use the bathroom and crew did not tell us what was going on or give an estimated time to expect to be at a gate.

Both of my flights to and from JFK experienced significant delays. Most notably, my first flight was delayed by six hours due to crew members being affected by delays on a previous flight. While I understand that disruptions can occur, Delta’s staffing and operational planning should include sufficient contingency measures to handle situations like this rather than placing the full burden of those delays on customers. Additionally, the $12 meal voucher offered as compensation was inadequate, particularly given the high cost of food and beverages at the airport. Considering the length of the delay and the substantial inconvenience caused, I believe more meaningful compensation would have been appropriate.

This flight has a history of leaving late, however, I was pleasantly surprised that it was not delayed this day. The flight went smooth, except I was in a window seat and the wall and my feet were freezing. I found it difficult to sleep due to being so cold, I also was using 2 provided UAL blankets and could not get my feet warm. This was annoying, but I still made it there on time and safe.

Staff didn't seem confident about the ingredients in my lactose intolerance meal

the seat has a problem. the back had a hole.

The back to back mechanical delays from Denver to San Diego and then on my return flight from Denver to Great Falls it added extra time both ways

Really old place. Not as clean as it should be, tray tables needed better cleaning. The items, trays and some other items need to b6 engineered. Anything task you or crew may do is incredibly load, seriously engineer for quiet smooth, easy. Just opening and closing the tray table is actually dangerous and can easily injure a finger. I'm sure it happens as it happened to me! First time I used United and likely will be the last!

Like the fact that the boarding was expedited. But the delay and chaos around the onboarding was not appreciated.

Flight was 2.5 late. Maybe not United’s fault but late none the less. We were late as well on the first leg. WiFi quit working with an hour left.

Old 757 with poor entertainment system. United no longer partners with United for free text and email. O'Hara an absolute disaster! Limited gates clauses two hour delay. Unfortunately this appears to be the norm.

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.

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.

The check in and boarding process was smooth, and the flight was fine.

We had a wonderful experience with Aer Lingus. The seats were too close for the long trip. The crew was absolutely perfect. They were so caring and thoughtful! My husband did not have a good experience with Air Lingus on the phone when trying to take care of getting better seating because he is disabled and needed a wheelchair prior to the day of our flight! Mariam R. in Boston was so helpful with seating and getting help for my husband. Filip Pytka who works for OCS was extremely helpful! He made sure that we had the lift because my husband could not climb the stairs to get onto the airplane. He took us from the gate all the way down to where we needed to be.

We were an hour and a half late, which caused my rental car company to cancel my reservation. We had no car, had to take a taxi to our hotel, and then a taxi back to get a new car the next day. Sometimes lack of on-time performance can end up costing the passenger a lot of money, none of which is covered by the airline that operated the late flight.

Overall good experience. But seats were small and uncomfortable for the price. Good entertainment, staff friendly and attentive.

Smooth quiet flight take off and landing both excellent. Food was mediocre. Boarding at gate was disorganized and unacceptable.

Delays and cancellations. Mechanics weren’t on site. Replacement plane took hours to arrive although it should have arrived within 90 minutes. Flight back was cancelled. Ended up driving over 12 hours and wasting 3 days between everything.

Flight was delayed multiple times and rerouted to different concourses in the airport because of all of American's delays. App/boarding pass would not update with changed gate information.

Absolutely infuriating. I was flying standby to get home earlier after flying 4 times with American in 6 days. I was #2 on the list with seats near the front and middle, in addition to the 4 first class upgrade seats that came back into the pool. I am a Platinum member, have their card, and they put me in the 2nd to last row in the middle. No loyalty whatsoever and they lost a fan for life. There is reason people have negative comments about American and I am done supporting them.

Horrible - their gate agents do not care and loyalty means nothing to them. Planes are often late and you are left on your own. Oh, and WiFi - good luck!

Awful! We boarded and then sat on the plane for 50 mins before having to deplane due to a maintenance issue which should have been addressed before boarding. Then we had to change terminals as there was no other plane for us at the current terminal. Then we waited another 2 and a half hours to board again only to wait for 50 mins on the plane again for the snacks to be brought from the broken plane. And once we were on the flight we still only got the complimentary cookie and soda or water. No food vouchers provided even though we had waited over 3 hours for our flight.

There was a 6 hours delay in our departure. And yet, no compensation was offered. A company should be responsible for such a delay.

Little bit of trouble getting my KTN and pre-check status onto the ticket, but otherwise the counter staff were friendly and truly concerned to get it right.

Plane was delayed for 3 hours, due to situation within aa control. Information was shared poorly. We sat on tarmac for over 40 minutes after the 3 hour delay.

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

It was my first time in Jetblue flight in 10+ years(?) and the experience was horrible. You were better before. There were ATC delays sitting/waiting in the tarmac for 2 hours, I understand that this isn't Jetblue's problem but how the matter was handled poorly is. Cabin was so warm and hot couldn't get it to cool down for the entire waiting period worse, even during cruise flight. Start, the passengers were spoken to and treated like a little children with no respect. Constant/multiple annoying tone/voice PA announcements of mentioning "... only big/large suitcases are for the bin and small ones need to be placed under the seat, etc,..." I see that flight was delayed and crew were trying to get the plane ready to board as soon as they can but the way they presented was lack of better word, condesending and scolding tone to cattle. It was definite unpleasant, unwelcoming flight experience I have ever had with Jetblue. Whatever happen to smiles and fun employees , pleasant/helpful gate agents, flight attendants, crews, where have they gone? It was dissapointing flight experience overall from everyone. Sorry for the direct transparency.

Flight was cancelled as JetBlue could not find a pilot. Communication was poor and they did nothing for stranded passengers. Flight they rebooked us on was 4 days out.

JetBlue cancelled the flight. We had to rebook on another airline.

JetBlue cancelled the flight along with hundreds of others, for no apparent reason. no recourse, no rebooking options. never booking with them again

Jet Blue cancelled my flight after I had boarded. They attempted to rebook me for a new flight two days later. I was able to rebook with a different airline, but not until the next morning. As such, I was forced to get an expensive hotel and missed important work meetings Monday morning. I am very disappointed with the customer service and will be pursuing full reimbursement for my hotel cost.

You did a great job rescheduling my cancelled flight. However, you made me pay for two seats for $118 even though the seats on the original flight were free. I think that was a very unfair thing to do.

They cancelled the flight after 5 hours at the airport and the only flight they offered was for the next day with a 7.5 layover in fll. This was not going to work for me as this was only a weekend trip and getting into providence at 10 pm a day later caused me to lose Mo ey on hotels money on airport parking a dog sitter etc. they wouldn’t offer any type of a voucher or anything else. All they did was refund the flight which didn’t help me with all the money in time I lost. I was going to see my very sick father

The flight was on time the crew was courteous that makes for a good flight.

A more comfortable seat. Padding would be really helpful but I've read the airlines don't want customers to be satisfied with economy seats.

When I booked, I included my checked luggage and when the bill was sent there was no record of this. Its was costly since I am from Trinidad amd Tobago. Exchange rate over seven dollars to one US dollar.
