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.

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 LingusEWR-DUBJun 2025
Eat and drink before boarding. Snacks. Hand gel and surface wipes . Don't expect a window if in a window row.

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Three seats in first class were broken and while they were able to still acommodate us it was looking very touch and go and they had others they could not acommodate

Mechanic delay in addition to a 2 hour change in takeoff time was frustrating.

Delayed due to thunderstorms and no in-flight service due to rough weather — both of which are out of Delta’s control. Flight was good overall.

The flight attendants in SLC were rude. I arrived 40 minutes early to gate. Ticket said I needed check in for seat assignments and tried check in and attendants said they weren’t doing it. And proceeded to never call me to give me a ticket so when time to board I received the very last seat. Please relay to employees to do their job better..,

On this flight I felt the food offering was not as complete as on previous flights. The tomato salad was a bit off and there was nothing additional such a bread or butter. The breakfast was only one option, so you either ate what they had or ate nothing. The crew was efficient, but most seemed frustrated throughout the flight. The flight arrived early and was obstacle-free, so I’m overall quite happy, but the shine in the rest of the experience just wasn’t there.

The seats got pretty uncomfortable pretty fast. The armrests are bigger than on other planes, so I had less room in the actual seat. My butt hurt by the end of the flight. :/ comfort was the primary issue. The crew were fantastic!

I believe that a four-hour trip should have a meal. Delta had none.

Great flight with Delta! Boarding was quick and easy, the amenities were solid, and the plane was in great shape. The flight attendants had a fun, lively energy while staying professional. All in all, a smooth trip — even managed to catch up on some rest. Thanks, Delta!

I was uncomfortably cold on the plane. Other than that it was uneventful and therefore as enjoyable as a plane ride can be.

There was supposed to be a meal served, but there wasn’t and the major toilet was out of order

Very small cramped plane for an international flight. Everything else was good, but it was maybe the smallest comfort-wise I've ever been on for longer than 3-4 hours and the trip was 7.5

I understand stuff happens, but plane failures are likely due to lack of maintenance. Additionally, air conditioning wasn't working, no snack/drink service, no WiFi. Fortunately, the crew was communicative and light-hearted. United grabbed another plane and we were able to get to our destination.

There was no food available for this red eye... one little waffle cookie for a 6+ hour flight... thank God I was able to sleep some

It is clear that someone knew, and competent, is in charge of food at United Airlines at least for the international flights. I was flying in coach, but the choices of the dinner were excellent. Tasty, and appropriate size. I had the beef, which was a little bit like a shepherds pie, and it was good. Nothing comparable has been served on a United flight in years. It will not be confused with three star food, but it is very good for airline food. Even better was the breakfast choice between a cinnamon roll and a breakfast sandwich. I chose the breakfast sandwich which was absolutely delicious and which I would happily order again at my local Starbucks or Panera. It is clear that someone knew indifferent is in charge of the food and it’s about time.

The flight was comfortable with the exit row and great service

Had to cancel first flight because Airporter Bus took over 3 hrs to get to airport which resulted in an extra $378 dollar fare . Is there anyway I can be reimbursed for initial fare since it was not my fault? Sent from my iPhone EJ Ledet

Plane was crowded and even when we hit altitude, the plane was hot, not enough air flow.

Flight attendant in first class gave poor service (like he didn't want to be there) and food was awful. We sat waiting for gate upon arrival over 45 mins.

The pilots were late and it made us 1 hour late. The meat was tough and bok choy was also tough.

Flight was delayed 3 hours. No food and drink vouchers was provided. They offered a mini pretzel bag and water .

Delayed flight that lead to a missed connection and a 5-hour trip became a 12-hour flight 🙄

Any flight to ORD after about 2pm this summer has been challenging. Flight was delayed getting in (coming from ORD) and that led to it not leaving before a ground stop due to lightening before they could fuel the plane, and so forth. They made up some time but we were still late in arriving at ORD, and that led to missed connections.

Food was ok, but not as good as I have had before on AA.

No issues. They did change our gate FOUR times in about 30 minutes which was mildly annoying but the flight was fine.

Great flight. No issues at all. I still think boarding could be more efficient but otherwise, a good experience.

Pretty good. The food was just mediocre, the boarding and crew were good.

The comfort of the seats was great, the crew eased my child’s anxieties and the fact that I had full cans of my beverage choice was great.

My flight got switched and my prepaid bag didnt transfer over properly so I paid to check ANOTHER BAG. I was placed in a middle seat and it was just miserable. At least it was a bulkhead row so I had legroom. The flight just never seem3d to end

4 hours late, including over +1 hour waiting in plane to take off. Baggage left behind too.

Sat on the ground in Cincinnati for 50 minutes before deplaning

Terrible. The test of an airline is how they deal with problems. There is very little to differentiate between airlines. Aer Lingus failed absolutely. They lost one of my bags even though we had more than a 2 hour connection in Dublin. Trying to get it back has been awful. In checking on line I can see that the bag is in Edinburgh and it was supposed to be delivered today. It wasn't. The number we have in the UK doesn't answer. I had to pay for an international call to speak to somebody. All the woman at the call centre could say was be patient wait. I can tell you when it will be delivered nor can I tell you who the courier is.

A little late, but an overall pleasant flight. Staff pleasent hand helpful, a great start to our holiday.

Poor check-in experience in Manchester. Delayed boarding and check-in agent never explained how to transfer in NYC to JetBlue.

Overall it was good experience and it was my first trip with Aer Lingus. One thing I was embarrassed was that someone occupied my seat so I was asked to use another seat. Due to this unhappy happening I almost missed the connecting flight because the random seat was far from the flight door. Food was fine, I liked the macaroni and cheese with fresh bread.

I was very disappointed that the online sys allowed me to get the boarding pass for the second leg of the trip, when I clearly request it for both flights!

It was my first transatlantic flight with Aer Lingus. Very enjoyable. Thank you for making international travel enjoyable again.

Excellent as far as the flight is concerned. Faro airport passport check was a huge delay and worrisome re missing the flight. 45 minutes there through passport control

The space between seats has reduced even further making it extremely uncomfortable. Couldn't even open the tray table properly or got compressed the moment the front guy reclined.

The seat pitch was a little tight for me, but I survived. There was a volatile, enraged passenger a couple of rows ahead of me and the cabin crew defused and resolved the situation calmly, quickly, and successfully.

My experience with Aer Lingus was nice, and I would be happy to fly with them again. However, my seat pocket had not been cleaned and had dirty wipes in it. I have flown with Aer Lingus before and do not recall anything like that happening, so presumably this was a one-off kind of thing. For the meal, I asked if there was possibly one without my allergens and the flight attendant gave me the one she thought would be fine. She did not know what allergens were in it, but when I received the meal the allergens were all listed right on the top of the package, so I was confused about why she didn’t know how to check what they were. In future, I will see if it’s possible to request an allergen-free meal ahead of time. But overall, I had a pleasant experience. My experience with Underpricer was very unenjoyable and because of them I do not plan to book through Kayak in the future. I have used Kayak numerous times, but this booking experience was so unpleasant. They called me numerous times and also emailed me to try to get me to select a seat. However, when I had a question later on, I was kept on hold for 20/30 minutes before I finally hung up. I also emailed them but never received a response, which I did not appreciate, especially given their previous frequent calls when they wanted something from me.

Everything sucked. No food, one small glass of water, a tiny coffee, 5.5 hour delay with no customer service. Would never recommend flying them.

The crew was wonderful at check in, the gate and on board. Felt the luggage had more room than the passengers. The seats were smaller than most domestic U.S. airlines. I'm only 5'2" and I had little legroom. There were only 2 bathrooms in coach. Needed more. The flight was very smooth but not the most comfortable.

There was no lounge at Boston for us to use. Typically flying first class overseas comes with lounge privileges. The seats did not recline even a little. My headset only worked on one side. I felt like I was flying on Ryan Air, not Icelandic Air.

The flight was delayed and as a consequence we missed our connecting flight. Were stuck for another 6h in Reykyavik. Appreciated that we got a generous food voucher at least. Would have liked to see more information upon arrival including a person waiting for connecting flight travellers and informing already that we will not catch the flight and directing us to the office dealing with the matter; unfortunately that didnt happen and we hence first needed to find out whether flight had indeed left already and then locate the adequate office to help us with booking us on the next connecting flight. Also my suitcase broke and it is not clear whether it is happened on the leg with Iceland Air from DC to Reykyavik or on the leg with Lufthansa from Reykyavik to Frankfurt. Finally, understood that it is a low cost company but at least provision of earplugs for free would have been nice, instead of making them buy.

Great experience on Icelandair flight from Newark to Amsterdam by way of Reykjavík. Courteous and professional staff. Food was solid. Service - outstanding. Cabin was a little warm.

Good service. No complementary food for international flight. WiFi kinda pricey. Got the job done for the right price.

Still one of my favorite airlines, but the entertainment options were a bit lacking. It didn't help that my screen didn't work on one of the legs of the trip.

The plane was very small and the aisle was so narrow that every time someone walked by they rubbed against me, so it was very uncomfortable.

Everything was good. Only issue comes from being vegan and flying. The food options are super limited.

Overall good for an economy fare. IMO the movie selection could be improved. Great that you can now connect bluetooth headphones to the entertainment system.
