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.

Both legs on the way were smaller planes, each had a mechanical issue causing a delay

Delta exceeded my expectations! I am beyond satisfied. Thank you!

Flight was on time! That's the most important thing for me.

Delayed flight. Dirty seats, dirty seat belts with food stuck on it from previous passengers maybe. No one cleaned the seats or flight.

The flight was delayed and knowing I was going to miss my connection, nothing was done proactively to try and get me rebooked. It was an act of congress to do so. This is not on the crew, but on the experience itself

No headphones, forced to sit in another seat that I did not book, had to check my carry on when I boarded the plane I saw backpacks and other non carry on items stuffed in the carry on holder! Horrible experience Wi-Fi did not work either

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta is getting worst by the minute. Where this was at one point my only go to airline, it has become like a budget airline

All was fine. Small plane so no food or entertainment.

Very disappointed in the crew as they did not pick up my trash nor offer headsets

The crew was great. The food was typical, but decent. Everything else - mediocre to poor. The flight was late arriving - happily for us and our 49 minute connection (what idiot came up with that?)- in another concourse - that concourse changed before we arrived (ticket and app was showing the incorrect gate - when we boarded at the correct gate - known by the airport person pushing my assistance cart). Had I walked and read the screens or United app I would have missed the flight! May other people arrived late to the correct gate, having been victims of a last minute gate change, were also relieved the flight arrived late. The aircraft (Boeing 757) was a sardine-can due to an uncomfortable seat pitch distance. The material or seat was beyond not comfortable, but I'm sure they made a lot of money with that aircraft type. I spent a lot of time standing in the back (in the middle of the night/morning to rest my back). I learned my lesson - any trans-oceanic fight - avoid United or American Airlines - and look for Airbus or Boeing 737, 767, 777. Also, pay for business class or premium coach seating.

Great Brasilia aircraft - not a Boeing 757 like the next part of the flight. Flight from MCI to IAD was great, on-time, comfortable, did I mention that? The flight from IAD to EDI was painful. One of the reasons I won't fly United again? Boeing 757, with a seat pitch and material that was horrendous. Worst aircraft ever, made worse by United sardine-can tight seating. Oh, and the connection window, 45 minutes, really? At IAD, in different concourses? What idiot came up with that flight scenario? Happily, (for me and my travel insurance people) the flight was late (reminiscent of American Airlines). The crew was professional and courteous.

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

Awful. Delay after delay. And then again on the tarmac.

WiFi was slow as compared to trip down. Maybe because it was a night flight and more people were using it?

Excellent except for the 2 screaming kids who wouldn’t stop crying and screaming for the entire flight but what are you going to do? The flight was early- good experience

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

It was partially ok .. not anything like from Orlando to Houston... first the flight attendant was not so nice and insisted on have a small backpack down when really was not to put in danger anyone, also the beverages they were not so good... not big chance to select other tea.. the seat was partially ok could not have those flips to hold your head.. and finally when it land off in Guadalajara, it was raining and the flight was going to the main area then go back and drop us out of nowhere with the rain.

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.

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.

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.

My flights were all delayed , mostly due to technical issues with AA aircrafts. I had to rebook my trip 4 times . I lost my whole day and finally arrived in LAX around midnight. This was a very bad experience with American airlines , I will always try to avoid flying with them

AA was fine....the overall experience was subpar, but not due to the airline due to broader issues

Delayed and WIFI was not working for most of flight.

The big challenge here was that the inbound flight was delayed, THEN, the aircraft was deemed in need of service, so we had to deplane after being a few minutes away from departure, THEN we had to switch terminals, where another plane in our gate had maintenance issues so we had to change gates again. I am a regular flyer (not on American) so I understand these things happen. The crew was great. The pilot in particular was gracious and understanding and stayed with the passengers the whole time to answer questions and give updates - that was impressive. But the flight was massively delayed as a result, and today I really wanted to be home in time. Sigh The flight was otherwise great.

I am Plstinum Pro snd was standby on earlier flight. They gave seats to people that asked rather than follow standby order. When realized what was happening was too late to get on as no seats left. My scheduled flight was late. Then filled the seat beside me Ruth rude person that they had to move from her original seat

My flight was delayed close to 10 times over the course of the evening. I was originally scheduled to depart at 7:03 PM but did not leave until 12:33 AM, resulting in over 9 hours spent waiting at the airport. The only explanation provided was that the aircraft kept being swapped, with no clear reasoning as to why. Weather conditions at both DCA and Tampa were clear, so that was not a factor. The only accommodation offered was a $12 food voucher, which was entirely insufficient given the length of the delay. Overall, I was completely unsatisfied with this experience. A delay of this magnitude with no meaningful communication or accommodations is unacceptable, and I would have expected much more from American Airlines in terms of customer care.

No ground air conditioner for the plane. Very hot and humid prior to take off which was an uncomfortable period of time.

Check-in process was poor, very poor, only one person to check-in all passengers, so if one passenger had a check-in issue, all other passengers were delayed. All check-ins should have two airline staff to check-in passengers.

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

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

awful expereince. boarding was a mess and not communicated, then we sat on a hot plane and were at risk of getting kicked off

2 hour delay and a lack of air conditioning on the plane. Not a good combination

Fabulous! This was the first time we've flown with JetBlue and the entire experience was flawless!

First time flying JetBlue and my perception changed. Love it.

Poor, had a 5+ hours delay. Kept sitting in the aircraft with three kids. It was terrible

The plane was filthy and worn - the seat pockets were stuffed with tattered food and torn pamphlets. The cleaning crew that came on as we were deboarding were grabbing handfulls of trash and perfunctorily wiping down tables with dishrags. It's been a while since I flew Jetblue and it used to be a great experience. After this flight I will avoid flying Jetblue again if there is any alternative.

I have flown Jet Blue many times between JFK and SFO. I appreciate how clean the planes are, the ability to select my onboard entertainment and the flight crews have always been amazing! Unfortunately, my trip from SFO to JFK on August 23 was unusual. I arrived early at SFO for the 12:00 noon scheduled boarding. The flight was supposed to take off at 12:45pm but after sitting for a while, the plane had to return to the gate to have a generator inspected. After deplaning and then reboarding, we eventually took off around 3:30 pm. It was explained to the passengers that because the plane was using a backup generator, additional fuel was needed and the flight would take longer than originally scheduled. We were originally supposed to arrive at JFK at 9:32 pm but instead, arrived at midnight. Unfortunately, I was exhausted for the funeral I attended the next morning. As a passenger, I have always expected that the plane will be in good mechanical order and that all parts will function as expected. I'm not entirely certain that if I fly Jet Blue in the future, that I will have the same level of confidence that I had become accustomed to. Thanks for the opportunity to provide this feedback. Kathy Nigro

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.
