During the flight, the fleas biting me in the plane.

Delay rushed to the next plane and bags didn’t arrive in chicago

Boarding could've been improved a bit, the rest is excellent.

Agents helping disable person doesnt know connections to Poland and after 9 agents helping and 2hours ,we made it to proper terminal. Polish Dreamliner its Polish nightmare liner with so narrow seats and no room under front seat for bag and feet,in economy class.To upgrade, to higher standart cost an arm and leg ,even there are empty seats No good experience overall

The crew and flight were amazing . However , my bag’s locker got broken and no refund provided . Everything else was amazing except this bad incident that ruined my experience

The seats are small and the movie selection was disappointing. However, the food was excellent and the cabin crew was attentive and kind.

The customer service rep on chat refused carrying golf set at no charge that is customary for LOT and others. I wanted yo carry just ONE club not even full set! Web check in was nightmare. Most horrible lounge at warsaw. To call it business class is a BIG exaggeration. Rude staff warsaw to nyc. Seats uncomfortable and not flat as is now customary. Bad content and entertainment system.

Seats were so uncomfortable, my butt hurts so much, I wish they have more cushions,it really was horrible, Except that, Stewarts were polite food was decent

The 737 lacked business-class seating. It was basically economy plus but with the middle seats left unsold. There were no TV screens but good food and service.

Everything was good, flight was smooth and on time Like service

Dear Aer Lingus Customer Care, I am writing to formally raise a complaint regarding my recent experience on Aer Lingus flight EI53 from Dublin to Seattle on 22/08/2025. Both my wife and I were seated in 15D, 15E directly under a faulty air conditioning unit. Even though the unit was switched off, cold air continued seeping through the sides and blew directly onto us for the entire duration of the flight (over 9 hours). We reported the issue to the cabin crew, but the only attempted solution was placing a piece of food-packaging sticker over the vent. Unsurprisingly, this had no effect. When we pressed further, the crew told us: “It is hard to fix it because we don’t have an engineer on board.” As a result, my wife and I remained exposed to constant cold airflow for the whole flight, and both of us became unwell afterwards, experiencing chills, sore throat and fever at the end of the flight. This has caused significant distress, disrupted our work plans. This experience highlights both a serious maintenance issue and a lack of adequate care for passengers. We therefore request: A full investigation into the defective AC system on this aircraft. An explanation of why no effective remedy (such as reseating us) was provided. Compensation for the illness and disruption caused to both myself and my wife. We ask for a full written response within 28 days. Should this matter not be satisfactorily resolved, we are prepared to escalate the complaint to the Irish Aviation Authority and Commission for Aviation Regulation and other relevant authorities. Thank you for your urgent attention to this matter. Sincerely, Temuujin Tuvshingal Myagmarsuren Ganbold

Seat is business could have been a lot cleaner, but space was nice and seat was comfortable

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

Not JetBlue's fault but Aer Lingus never explained how to transfer 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.

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 was reduced even further. Could not even open the tray table fully and got compressed the moment the front guy reclined. For a long haul flight it was extremely uncomfortable.

Not satisfying due to loss Luguage for 4days. Damage Luguage that had no way to fill up a report for and me as a client to spend more money and time to replace it. Thank you for soliciting my opinion, but it was unfortunately a very disappointing experience. Stephanie Zvi

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.

We booked a flight from FCO(Rome) with a stop over at DUB(Dublin) going to JFK. Boarding from Rome was kind of chaotic since the airport I guess is very small and we needed to shuttle to the airplane. The gate agent just let everyone and anyone go without using the sections so that took a lot longer than usual boarding. From drinking to JFk boarding was good and organized. Amazingly the flights was very smooth sailing and we’ve flown American big airplane to small companies before. The aircraft’s itself is on the older side, can’t complain tho because the plane ride wa smooth. For a 3 hour plane ride, nothing was complimentary. But for the longer leg of the plane complimentary snacks, meals and drinks were provided which was great. The food wasn’t bad either. I would fly with them again, great price and good service.

It was good. The air plane is clean and staff were friendly.

Worst airline I’ve ever flown. Delayed 5.5 hrs, missed connecting flight, and missed an entire day of vacation. Zero customer service

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.

Boarded with no problems. Sat on the tarmac for an hour before taking off. We were the last ones on our connecting flight. Didn't think we were going to make it. Our flight to Iceland was similarly delayed. When we've flown other airlines, pilots have tried to make up time while in the air. This doesn't seem to be something that Icelandair does. We made all of our flights, but it was stressful and we didn't think it was going to happen based on the time we arrived.

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.

I darted through the Frankfurt airport to make my connecting flight. I asked if it was a possibility to upgrade and the agent did. This was the kindest gesture and it made up for the previous delayed flight and distress/anxiety of anticipating that Zi was going to miss my Frankfurt-Chicago connection. I cannot express my gratitude for the upgrade.. I am 5feet 10 inches do the leg space was amazing.

I meant this flight was not good, the one from Tirana to Frankfurt was better!

I was very grateful for Lufthansa's role in organizing mobility support. The touchscreen on my seat was faulty: slow, stained (I couldn't get it clean), and glitchy. This made selecting movies extremely time consuming, and twice I had to start all over from the beginning.

The crew was the best I’ve ever encountered. Business class was spacious, immaculate, and very modern.

I wish seats were not reclinable. It's so claustrophobic when the person in front of you spends most of a nine hour flight leaned all the way back. The crew was really nice though and the dinner (red Thai curry) was pretty compelling.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.

The boarding system was all bogus - employees at the boarding gate were not sound like proffesional or may be possibly rational

I got an email in the morning of the flight 1/7, from Kayak, that I was rebooked from UA 906 to LH 430. Nobody at Lufthansa ot United knew about this. I went to both counters. at the airport. Also, Cheap Flights, who I booked the ticket through, did not know. I ended up staying on the United flight. But this was very disturbing, since I got a very late notice that I was rebooked to an earlier flight, I hurried to the airport to find out after a lot of inquiring that this was a mistake. Not a good Kayak experience.

After living in Europe for five years and flying with Lufthansa and KLM airlines, I’ve realized that United Airlines is now a budget carrier. The flight attendant are not friendly. The seats are not comfortable. And everything comes at a cost. I will be flying with KLM and Skyteam like Delta to the US going forward no doubt. United Airlines is not what it once was:

Delayed take off but I think they waited for passengers.

We missed the connection because we had to wait for a shuttle from the plane to the Terminal. Also, we needed assistance and none was available.

When we arrived at the airport - 1st step - printing out your boarding pass - no issue. Not long lines as these machines. 2nd step - processing your bag drop off. There was only one associate there to help 10 kiosks. We had a family in front of us for 20 minutes trying to work on the machine and figure out every step for 4 pieces of luggage. My husband alerted the associate who was able to assist the family. Highly suggest that there are more associates to assist in this process. Besides this issue, security check went very quickly. Our flight was direct to Philadelphia. We had to carry our bags down two flights of steps, then out to the tarmac to a bus, then carry our bags up two flights of stairs to the plane. No one on the flight was expecting that long trek. I could see some people were struggling a bit. All in all - great flight crew, plane was clean and food was great!

There were no gluten-free vegan options available, so food was very limited on this flight, and some of the crew weren’t especially helpful about it. To make matters worse, a passenger was sick on board, and although the area was cleaned, the smell lingered for the rest of the journey. On top of that, we ended up circling for an extra hour, which only made the unpleasant situation drag on even longer.

Checking in prior on line and wait time at Gatwick was terrible. I would rate a big fat ZERO.

There was a slight delay. Otherwise, everything else was satisfactory.

The company that I bought my tickets through, Cheapflightsfares, failed to provide my confirmation information in a timely manner, so I was unable to check on at the country and therefore unable to make my flight. As a matter of fact, I STILL have not received the confirmation. After having read more and more reviews about the company, Cheapflightsfares appears to have scammed hundreds of hopeful travelers out of thousands of dollars. Please look into this company and, for the sake of anyone planning their next trip, stop allowing them to do business through you.

I checked in to bags, one arrived one was delayed. I did not receive the bag for 4 days - arrived on Tuesday, received bag on Saturday!

It was ok. Our flight was delayed 2 hours, and then again on arrival. The explanation given felt feeble.

The plane was known to be late in advance of takeoff. My guess is that it was known to be late at 11am or 5 hours before scheduled takeoff time. We were late to leave and with a wheelchair and the a cart, we only made it to gate. We raced! Inside plane, all was great

The booking agent, cheapflightsfares, messed up, and the information for the seats we paid extra for was not sent to American Airlines. We were separated on the return flight and sent to the lowest economy section. The flight attendant helped arrange seating at the back of the plane to allow my wife and me to sit together.
