Liked fold flat bed. Didn’t like having no window. Didn’t like poor choice of food and being served dinner very late, hours after take off of a 7:40pm flight. Servers not friendly. Food horrible in business class.

Everything is good except the dinner and breakfast. The sandwich is very delicious. Toilet is clean, I only use one of them. Flight attendants are very nice. 👍👍

A bit rush for transit. Food and entertainment are not available

Boarding was a little difficult. The gate area at O'Hare was very small and crowded due to multiple gates in the area. Could not hear the intercom, so had to rely on signage to see when my group was boarding and the signage was blocked by passengers standing in the gate. Flight was great and we arrived in Montreal on time.

Multiple delays and not straight answer from the United team

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Stewardess spilled orange juice on my clothes/seat no help no apology just threw napkins at me to clean the mess up. Not Happy.

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

The plane pushed back from the gate on time. However, it stopped on the ramp, and we waited for over 20 minutes before the aircraft pulled back to the gate. Apparently, something of importance had to be removed from the aircraft by the gate agent. I found this to be odd. The delay was not significant, but I felt that whatever was on the aircraft that had to be taken off, should’ve been done before we pushed back from the gate.

I didn’t get on plane. Passport being processed by consulate with visa application. Tried to cancel through underpricer after purchasing cacelling for any reason. No dice, they are thieves.

Everything about the flight was lovely…We left early, arrived early, cabin crew were efficient and helpful. Flight was easy and most pleasant.

Everyone was nice. It was on time and the food was. Airplane food, but not horrible

One bottle of water and a package of cookies for comfort plus. We had to literally beg a flight attendant for an extra bottle of water later in the flight due to feeling dehydrated.

late again! but its my only option to not take 9 hours to get to Memphis

Almost everything was outstanding. First, we boarded on time and the flight crew did a great job getting everyone seated. Then the pilots took their time and care to make sure the plane was full de-iced three times as there was a bad ice storm a few hours earlier. The plane ride was smooth and comfortable and even the economy seats had decent room and comfort. Flight Attendant Lisa went above and beyond to make sure I was comfortable - she is outstanding. The only thing wrong with the flight, and it is something which needs to be addressed, is that the gate to gate time was over 6.5 hours and not one meal was served. The only thing offered to eat were two small cookies for a transcontinental flight - unacceptable. Charge me more but give me a meal for a long flight. Thankfully Lisa found something for me.

Very poor. Our special services attendant gave us incorrect information. I also was mishandled at landing. There was no wheelchair waiting. I fell deboarding the plane. Appalling!

I had a very unpleasant encounter with one man from customer service: he was extremely rude and miserable. And his condition was reflected on his decision to send me to the worst airport hotel and get an awful flight connection. My hotel shuttle had never arrived and I had to book another hotel. People served by other representatives got a much better treatment and deal.

The flight left a bit late, but arrived close to time expected…With the flight being close to full the crew did well serving drinks to all in a very timely fashion. The flight was a pleasure…

They didn't have any gluten-free snacks, oddly, which I require...or any flavored soda water or decaf tea options, which seems to be standard.

My flight back my reservations were list because they said I didn't pay my pet fee when I had a receipt

All was good except for the seats, not very comfy.

2.5 hour delay sitting in the plane on the tarmac, you tell me how the experience was

I hope these comments will find their way to AC customer experience team. Me and my spouse 50 years of aged coming back from 7 days perfect vacation... While boarding in FLL flight AC1621, one of the boarding agents (tall aged african american) man literelly yeld at my wife during the picture talking process. MAM ! STEP !! BACK !!! We are not illegal immegrants beying deported, nor are we in the millitary. We are customers returning home. This was unacceptable. While boarding in YYZ flight AC1154, one of the boarding agents (tall aged caucasian) man criticied with several complesant remarks my passport condition saying that I could not travel intl with it due to stain, decoloration, and BLOOD. My passport does not have blood on it! Yes it might be in less than perfect condition, but their are ways to talk to customer that does not imply not allow a boarding agent to be angry fathery like, or a custom agent looking at a suspicious individual. Both experience were less than acceptable for might I remind you a paying CUSTOMER returning home.

Short flight so no food or entertainment. Good landing at SFO and on time. We were told no carryon luggage yet lots of people were puting bags in overhead compartments. The rules need to be made more clear. I was on the first leg of an international flight and this is the first time I could not have carryon luggage.

This flight didn't happen for me because of overbooking.

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.

Comfortable seats and movies entertainment available. Better experience than the flight from Toronto to Denver.

Poor air traffic controller staffing led to a 50%reduction on flights so we got to wait 4 hrs for our flight! Very disorganized at the gate Poor communication with customers

It was delayed by almost 90 minutes and that messed up our plans but it was beyond UA’s control that is what we heard

Terrible experience, flight was delayed both ways. Limited compensation for the 5+ hour delay. Will not be flying Air Canada Rouge, and don’t recommend you do either.

Food was very bad. Boarding was disorganized and messy. Crew was friendly

Noted in last review. Good to know, though air Lingus on European flights does not offer any food or drink, even though we were on the plane for 3 1/2 hours from Naples to Dublin everything you had to purchase even water.

Seats were alarming close to the row in front of you. I didn’t do the measurements online, which I’m sure they’re available, but it seemed much tighter than other planes, but the airplane itself was well maintained and looked fairly new. My only complaint on the staff was that we’re on an international flight. Normally they give you wine with dinner and the flight attendant decided to pull some strict restrictions and wouldn’t give more than one glass of wine per person, and you could not share with your spouse, which seemed ridiculous when we have four people on the plane with us and only one person ordered wine asked for a second one and she said oh absolutely not. It’s only one per person Which on a transcontinental usually is not the case. They’re very attentive on making sure everyone is as comfortable as possible.

Booked through Kayak, couldnt take flight, Kayak punted to Orbiz, Orbiz punted to Aer Lingus, Aer Lingus said sorry about your luck, try Kayak/Orbiz. Terrible customer service collecting air fares and not even offering a voucher when customers cant take flight

There was no flight. I booked a flight from Toronto to Bordeaux with a stopover in Dublin. I arrived in Dublin and the flight number I had didn't exist and the flight going to Bordeaux I wasn't on. I had to book a new flight with a different airline for later in the day and pay out of pocket.

Gate agents kind of serious. Had to wait til arriving at gate to choose seats. Thankfully they did give us seats together! And grateful the honored our age, giving us seats at the front.

Very polite and helpful staff. Jet blue…ok, but not as helpful!..

Seat was very uncomfortable. The worst in all of my travels. It sagged in the middle, worse than anything any airline can offer. Not flying aer lingus again.

This flight was delayed and caused me to miss my connecting flight from New York to Boston. I had to rent a car and drive myself home to avoid waiting another 5 hours in the airport.

My Aer Lingus flight (booking ref # 2SU4LF) was the worst travel experience I have ever dealt with. My flight from Paris to Dublin was delayed by over 2 hours which caused me to miss my connecting flight back to the US. I was not able to be rebooked on a new flight for another 3 days. When I finally made it on my rescheduled flight, it was delayed AGAIN, causing me to miss my connecting flight from New York to Boston. At this point I decided to just rent a car since the next flight I would have been able to get in wasn’t for another 5 hours. It was a complete nightmare experience and I will never fly Aer Lingus again. I have requested a refund from the booking company I placed my order with.

Nice flight, attentive crew, soft landing by the Pilot,, comfortable seat.

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.

Too much long line at the TSA and Security. Prepare for long walk for baggage claim.

The flight from Seattle was delayed, which made me miss my connection to Florence. I was re-booked NINE HOURS LATER!!! That’s basically a vacation day lost. British Airways needs to partner with other airlines when possible to get a more realistic travel time, if delays occur. I realize there aren’t many flights to Florence from London, so I would book differently were I to return. The actual flight from Seattle was very comfortable and the crew was great, no faults there. I enjoy British Airways, this was an anomaly.

The crew could not have been more helpful, my meal was excellent, I slept peacefully until right before landing, and the BA lounge was a godsend. The only negative I encountered was the coffee both on the plane and in the lounge. Not to my taste but that’s a personal preference.

I don’t understand why a reputable airline like BA would delegate their London flights to AA. Makes no sense to me, as most domestic carriers do such a poor job these days. Terminal 3 at LHR is a total dump

The boarding process was quite loud and chaotic. The flight attendants kept barking over the PA system about people needing to only stow large items in the overhead bins. During the one and only service, I was hit by the service cart. At the same time, a passenger was returning from the bathroom and the crew definitely saw him but stopped a few seats short of allowing him to sit down before starting service and made him wait a good 10 minutes before passing his seat and allowing him to sit down, after which he had to ask for his snack and beverage or he would have been passed over. Neither flight attendant thanked passengers as they left; in fact, I did not see them again once the plane door was opened.

Cancelled flight minutes before boarding. Rescheduled flight was two days later

The flight attendants were EXTREMELY personable and appreciated the service, lights going off after dinner (probably the norm, but I haven’t flown evening overnight flights in a while). Thank you!

Business class seats were very dated on my plane. Very little storage, charging ports were not easily accessible, tv screen kept flopping away. Vegetarian food was disappointing: hardly any protein and severely under-seasoned. Crew was lovely.
