The boarding of took of late.The presentation of the food was horrable as was the tast of the food was cold and tastless.

Flight attendant moved my bag without notifying me and was rude to me when I asked him about it. There was no reason to move it.

Flight was On time and landed 30 mins early considering we were flying into Newark. No complaints.

The flight was canceled the day of the flight. United says it was FAA issue, with some 35 flights canceled and more delayed.

Very nice and clean plane. Transit time between flights was tight though

I needed to make changes to my flights. When I called customer service, they assisted me with care professionalism.

The design of the light switch on the arm rest is ridiculous.

I just got back from a trip with 3 flights each way. The flights were good and we were happy with out experience. There was one steward on our first flight that was harsh and grump with passengers. It did not leave a good impression. All of the other flight crews were great on the other five flights.

Mostly the experience was good except for the flight changes made by UA which meant longer layover in DC

Delays took 2hours and thirty minutes making me miss my connecting flight and make me sit in the Chicago airport for 9 hours

The flight was fine but the 8 hour delay in Chicago was awful - 5 gate changes and repeated delays without an explanation. No vouchers. Nothing.

The plane was probably full boarding was easy. We were able to check our carry-on luggage for free. It was a return flight through Philly to LA. Never saw a stewardess do a demonstration of emergency Procedures. I think my flight was pretty full

Plane, flight, crew, captain were all great. The first flight had a Chipotle box lunch...delicious. this return flight not as tasty, but filling.

Not sure the logic of the boarding in Groups. I was loaded first on the aisle. Then the guy in the middle. Then the guy by the window. Constantly holding up the other people boarding behind them with us blocking the aisle and this happened in most of the other rows

Uncomfortable seats and flight attendant was rude as she insisted on waking up my husband to ask him if he wanted a drink. When he said that he was sleeping, she replied “without an attitude “. He was seated at 8c

Very friendly and efficient and smooth boarding. We were even way early arriving at my destination. Thank you.

I didn’t like anything, being platinum pro get you absolutely nowhere and does not increase the customer service treatment whatsoever anymore. My flight was canceled and they put me on a flight eight hours later that would’ve got me back in the middle of the night. They could’ve easily move me up to an hour Prior on an earlier flight. My second flight was unreasonable to take, the third flight was also canceled due to mechanical issues like the first flight. I don’t know what’s going on with American, but they are falling apart, after seven flight changes I finally got home, Unreasonable.

At least it was a short flight. Greyhound with wings.

Everything was great except it became so hot on the plane I couldn’t sleep on my red eye flight. It didn’t really cool down till we started descending.

The seats were crammed and the guy in front of me wouldn't stop reclining. If AA is cramming extra rows in, they need to take away the reclining in coach. My knees were smashed for 4 1/2 hours and I was very close to confronting the passenger in front of me.

Flight was in business class on an older Lufthansa 747. Business class seats definitely old style. Flight attendants were a little curt but attentive. Movie choices did not include anything that would be considered new releases.

My luggage passed security but just before boarding the plane I watched as my luggage was thrown on the belt to enter the plane in Windsor and my luggage cover was half off. it was damaged before even making it onto the plane! I’ve had the luggage and covered for a year and have never had any issues. I mentioned it to an Air Canada employee who told me to use the app to make the crew aware of this (she said so they could fix it) but sure enough my luggage was damaged with no cover in sight! I sent an email to AC that was ignored. Awful experience! Also, a 4.5 hour flight and you are offered pretzels or a cheap single cookie?? Wow. The return flight did not have any entertainment available unless you used your own device and their wifi. The USB plug on the back of the seat did not charge my phone so my battery drained by using it for a short period of time. There was no warning that this was the case prior to boarding the aircraft. Lastly, the plane was freezing. I asked if they had any small blankets (which used to be standard) and was told they were only for the front section. Would never fly AC again!

The food could have been better. The flight attendant was the friendliest and most helpful I have ever had.

Terrible food, unprofessional flight attendants, and an uncomfortable seat. The food they provided was the worst I have ever had since I flew. They were worse than any cheap food you can get at convenience stores. A flight attendant talked to me in an insulting and demanding manner. If she wanted to say something, she should have said it professionally and kindly. No flight attendants served any drinks or snacks. If I needed a drink or snacks, I had to get up from my seat and go to the airplane's back area and serve myself. What were the flight attendants doing during their work shifts? A man sitting in front of me fully extended his chair to the back, so I had virtually no space to eat with reasonable comfort. Many people were so inconsiderate of others and fully extended their chairs to the back that they did not have enough space to eat. Flight attendants ignored these situations and never bothered to tell passengers to return their chairs to upright positions during the mealtime. I want to be comfortable and don't care if others feel uncomfortable because of me. Those were the dominant thoughts of people in that airplane. I paid more than $2000.00 for this terrible experience.

Everything was fine, crew was great. Always appreciate an on-time flight.

My flight was overbooked and they would not let me board. I had to book another flight and pay the full amount of that flight. I did not get any help at all from Air Canada or United Airlines.

Crew was pleasant and efficient. The speaker system for instructions was hard to understand

Very crowded; wanted us to check in 1 & only carry on full of meds & supplies; crew very reluctant to approve! I’ve lost checked in luggage in past.. It was non negotiable in my mind!

Ok Did not like that the second leg of flight was moved earlier making it a rush to make

Kind and accommodating staff. Comfy seats. Plenty of leg and luggage room.

Dublin to Boston was decent. Food and entertainment was included and that was expected for the rate paid.

The Nice airport was a horrible boarding experience. I have never experienced the kind of compressed mob (in the B12-B17 gate area) of people all unclear what was happening and no airport staff to assist. There was no signage and 1000’s of people waiting for any info for 2 hours.

No entertained. food and beverages were not complimentary. they lost my checked luggage which made my 10 day vacation unpleasant.

The food was mediocre, the coffee was terrible. The entertaining selection was plentiful. They lost my checked luggage which put a damper on my 10-day vacation.

Flight was on time. Boarding was quick and efficient. Seats were comfortable. Food was fine.

Weeeeeeell, you folks know economy class on Airbuses well--you're packed in like sardines. We may actually spring for more expensive seats next time, with a little room to stretch out. NO room to stretch out in Airbus economy class! :-) Apart from this, the food was decent (considering that it's mass-produced, and has severe spatial restrictions of its own), the staff were friendly enough, and there was a wide selection of movies, etc. to watch. Overall, I'd tend to use the word "adequate" rather than "exceptional" for my experience. But really, how could it be otherwise?

The ease of boarding was good. I wish they had something to eat on the plane.

I like Aer Lingus so that is why I’m writing this critique so they can become better. The boarding gate was too small to board properly. Our seats were toward the back of the plane knowing we would be boarding after business class, we moved to that area after business class boarded. An Aer Lingus employee told us we couldn’t stand there. We explained we were the next group to board and wouldn’t even be able to hear when our boarding was called. She didn’t care and was not very professional. The cabin was freezing. I wouldn’t feed my dog the food. We were over an hour late coming into chicago because of weather which can’t be avoided. I asked the crew if they could make an annoucement for before whose final destination is chicago to wait and allow the people with connecting to deplane first. He said there are a lot of people with connecting flights. He said, it doesn’t matter. Well, yes it does. He could have been more considerate of his passengers.

The seat spacing was good. The food, not so good... typical airline food. 😕

I would face like to have more selections for entertainments overall it was very good. .

The crew were good. The flight was on time. The food was bad.

The airline was efficient and accommodating to work with though there was a delay. Appreciate the service and smooth experience!

The payment system was not working so was unable to connect wifi the entire flight

The boarding call announcements versus the Staff announcements versus the digital signage board on the out-going and returning flights WERE NOT IN SYNC. I was sent through check and re-checks 3 times. WHY?

Absolutely the worst airline. Can’t find anything positive to say. We were in business which is the same as most airlines coach

When checking our bags we were told our bags would go through our final destination. This did not happen. When boarding, after group 3 it was a free for all, everyone boards. When served lunch, I asked for anything without dairy, I was given popcorn and gummy snacks. She said she would come back with more options, she never did. Also, when traveling through London, they don’t tell you your gate number until 1 hour before flight leaves, causing everyone to run to their gate.

With three empty seats across the aisle from me I politely asked the crew if I could sit in one of those seats. They initially told me I couldn't do it for my safety. When I pressed them again they blamed the captain. So which was it? I didn't appreciate either nonsense explanation simply because they didn't want to honor my request.

Hand bag was taken to be checked in at boarding gate

I paid for business class…. And was counting on the usual packet of toilettes to be provided. They were not because not enough were brought on the plane so they could t give to some and not all. So no tooth brush nor eye cover. Then NO coffee since there was no hot water. The lay I er too short because of delays and my luggage didn’t make the next flight!! It is now a day later and I am awaiting to hear if my bag has arrived. Very inconvenient!. I suppose I need to be glad that I spend over $4000 since I doubt those in coach or premium economy even made that next flight..Heathrow is the worst.

Great room between the seats, food was excellent, very comfortable overall and could have stayed on the plane even longer
