Read more about Virgin Atlantic
Cons: "The service on Virgin Australia is quite poor. They are barely around. The seats are also only mediocre"
Pros: "Seat was comfortable, good movies, etc"
Cons: "We are a little hard of hearing. It was hard to hear the attendant when giving directions over the intercom. The speech was garbled and directions spoken too fast. I am not referring to the safety speech. Recommend slowing down so that we have more time to process what was spoken."
Pros: "Everything was easy"
Cons: "Business class seats are snug for big people compared to other airlines"
Pros: "Excellent airline"
Cons: "The business seats could have been wider. I have sat on business class other airlines and the seat was a bit wider but overall still great experience"
Pros: "The crew was very good and there was enough leg room."
Cons: "The dinner option was underwhelming."
Pros: "The business class seats are the best we’ve had. Plenty of room, nicely laid out, good organization design. The blankets were fluffy and very comfortable. Crew was super attentive and friendly. For such a long flight, it was very pleasant, will highly recommend."
Pros: "Boarding process was very efficient and crew was very pleasant and helpful. Seats were reasonable for economy."
Cons: "Meals were very small but tasty. Movie options were random but enough to keep you occupied."
Pros: "Comfort, service food and entertainment. What more can you ask for."
Cons: "Nothing. ]"
Pros: "Smooth overall. Food mediocre but edible. (More than I could say for other airlnes.) Price also good."
Cons: "Lots of flight schedules changes. Missed connecting flight as a result. No time left to deal with customs and baggage."
Pros: "Super friendly and helpful crew, food etc was fantastic very enjoyable flight. Thank you"
Pros: "Everything (with the exception of the subject below), thank you. One thing that really surprised me, though, is how much I liked the eggs (on both flights) and what went with the eggs, like the spinach and potatoes and bacon on this flight and the potatoes and sausage (and was there something else?) on the next flight. Kudos for making something that has got to be cheap taste good. Thanks."
Cons: "Come to think of it, there was one thing that I didn't particularly like, and that was how the headphones only worked on one side only (there was only audio on one side). At first I thought that maybe I had just gotten bad headphones, but the my next flight was the same: the headphones also only played audio on one side."
Pros: "The seats of the economy class are a little bit bigger than the rest of the airlines and are so much confortable to sleep."
Cons: "The crew speaks to quick and the Australian accent is not always easy to understand"
Pros: "food was great!"
Pros: "Lots of leg room, even in economy."
Cons: "Entertainment choices were a bit sparse."

Pros: "The food was okay"
Cons: "The gate was Jane without announcement"
Pros: "The boarding, the seats."
Cons: "The food was so-so, and I did not get my choices, perhaps because I was at the back."
Pros: "Flight was close to being on time. I was able to get a lot of sleep on the flight."
Cons: "Staff was not concerned about anything, vague and uncaring..this was my son flying across the Atlantic idiots!! One pissed mom!!!"
Pros: "Smoothest long flight I’ve ever had. No hassles checking in, boarding or leaving the aircraft. Bags checked through to final destination without any problem. Good employees at the check-in counter and at the boarding gate. Service was good at LAX."
Cons: "Cabin service somewhat spotty. I was not served breakfast and had to ask for a meal even though all those sitting around me were served. My wife did not get the coffee she requested even though it was promised twice. Trash accumulated at our seat making use of the tray awkward. I tried to pre-pay for extra luggage on-line before the flight but the web site would not allow me to do so. We paid $100 per extra bag at check-in."
Pros: "Staff was very friendly"
Cons: "Headphone jacks are costume, could not use my own."
Pros: "Crew was very solicitous...food was quite good.."
Cons: "Baggage was very slow in arriving. ..45-60 minutes"

Pros: "The crew was the best part of my experience, super nice and accomodating"
Cons: "the wifi had subpar performance"
Pros: "Met expectations."
Cons: "Things out of your control - time !!"
Pros: "No one would update that the flight was delayed. They would not even communicate as to why delayed and would not put us in a different flight. Absolutely no customer service. Disappointed and would not fly jet airways again . I missed my conference lecture today as I was late."
Cons: "No communication, nor will they tell you why it's late . Nor will they move you to another flight even wen requested"
Pros: "The crew were very friendly, and helpful. I also liked that the exit row that I was given had more than enough leg room, the dinner was really good for airplane food and snacks were great also. The attendant that I had for my section also told me that all food and drinks were free so they gave me a few extra adult drinks here and there which is a plus for how long the flight was going to be. The movie selection is great also having some on there that are still in theaters is a huge plus."
Cons: "The boarding process seemed way out of order, they made so many mistakes and nobody knew what to do, then you have the pushy passengers that are sitting coach getting mad that you're boarding before them. Breakfast left me wanting something else, lets just say this if you are given the choice of something vs french toast, take the something."

Pros: "The enforcement of the quiet time to sleep on the flight. The excellent meals. The quality of the entertainment system."
Pros: "nice new seats"
Cons: "The entre food top was torn, apparently opened before I got it, also there was no salad dressing. ATTN RICHARD BRANSON: Are you concerned for our environment? The head stewardess would not refill my sports water bottle after I asked her nicely, instead she poured water into a cup which she threw away, wasting plastic unnecessarily. I told her I did not like wasting plastic and she appeared to not enjoy what I had to say. This was the same lady who handed me my dinner. Rest of crew was great."
Pros: "Crew, fabulous, Plane configuration, GENEROUS, just the best flight I've experiences in a very long time!"
Cons: "Some meal choices were a bit sparse. That's my only complaint!"
Pros: "Nothing because I was given a middle seat"
Cons: "6'4 and I get a middle seat.."

Pros: "Everything was great ! The staff very nice and the plane is absolutely amazing .."
Cons: "We paid for extra leg but there was no difference between normal and extra .."

Beverage service was lacking…

Delta is a great airline with great options to fit travelers budget/comfort

Pros: "Good organization, good hygiene, polite crew."
Pros: "A box was under my feet, not sure what it was. A part of plane! ATL - EZE uncomfortable Crew great in spite of ongoing turbulence!"
Cons: "Aircraft was too warm. Needed more air!"
Cons: "The entire time there was a clogged bathroom smell coming in waves. The crew was forgetful of requests. Not a pleasant flight."
Pros: "Crew and service were outstanding"
Cons: "Good taste perhaps...?"
Pros: "compared with other airlines they were just OK"
Cons: "everything"
Pros: "The crews were very fast and efficient. The Dinner was good but the breakfast was very basic."
Cons: "The seat was so crammy and disgustingly uncomfortable"
Pros: "Check in person was very helpful in rerouting our flight."
Cons: "Our flight was delayed 3-1/2 hours. The gate crew booked us in another flight but did not issue a ticket, so after transferring to another terminal, we were sent back to the Delta terminal to be issued a ticket to a third airline since we already missed the second flight. Then, they lost our luggage"
Pros: "Seats are fine. Ordering system is up to date."
Cons: "After the first two hours of my flight (which I sleep through) I couldn’t buy a drink a soda or anything."
Pros: "Quick boarding"
Cons: "More water offered by crew"
Cons: "The fact the the toilette was kitty cornered in the mid cabin bathroom is a joke on modern society."
Pros: "On time, smooth take off and landing."
Cons: "Crew could be on time for work so the flights aren’t delayed"
Pros: "The Delta crew was great."
Cons: "Flight was delayed, for unkown reasons."
Cons: "Boarding was like a cattle call....my headrest was broken so couldn’t sleep upright but face down....seemed like a plane that large would have more bathrooms"
Pros: "It was Ok. Some short delay but over all not too bad. Just didn't like the fact I always get seats next to the toilet"
Cons: "The sits are uncomfortable"
Pros: "No delays..arrived early"
Cons: "Restrooms were dirty"
Pros: "Nice employees and service"
Cons: "Seat room"
Pros: "Entertainment"
Cons: "The plane was hot"
Cons: "Call center tried moving us to later flight that was also delayed by 3 hrs despite telling us it was on time. Fortunately a gate agent moved us back to orig flight"
Pros: "Call back service was best part."
Cons: "Booked ticket through venture card points. This meant that the email address and phone number to contact us in the event of changes was mediocre information. I was informed from Tripit that the flight was delayed, not by Delta. Reservation personnel took logical course of action to find new flight for connection that we could make because of delayed initial flight. I would recommend that they first see if there is an earlier initial flight that the customer could make, then look at finding later connecting flights. We found out about delay 8 hours prior, so we had plenty of time to get to the airport earlier. Total delay required me to take additional day off of work."
Cons: "Didnt fly from San Francisco to Atlanta"
Pros: "Entertainment"
Cons: "Attendant probably trying to be funny"
Pros: "Sky Lounge at SFO and onboard entertainment"
Pros: "Once aboard, flight went without a hitch and flight crew was attentive"
Cons: "The inflight entertainment options need to be expanded - I've run out of movies that I want to watch!!!"
Pros: "Entertainment. Large overhead compartments. Clean."
Cons: "The temperature in the plane was too hot and made for a very uncomfortable flight. The individual air conditioner spewed out hot air. My kids and I took off as much clothing as possible and still remained hot. We were putting ice on our wrist to try to cool down! I sat with my hand against the window to capture some cool air. We were in Row 37. I am not sure if we were in a hot seat or if the other passengers experienced the same."
Cons: "Delta airlines has very poor costumer service. THE WORST I HAVE EXPERIENCED. I wasn't the only one feeling this way, I witness a couple people fighting on the phone like me. When my 1st flight was delayed I asked to be rebooked then and the delta employee insisted that I would make my connection. I didn't make it. This is not all. I could have gotten to a near city several hours after but on the same day, but the mediocrecy of this employes did not allow me to get there until the next day at 7 am. Happy new year to me. This two women (or one of them) on the phone, lied to me. There was an option to get me here and one of them failed to do their job right AND LIED TO MY FACE ON THE PHONE. Just unacceptable. I will sue them, I had an under age waiting for me in Cancun and a pet with me!. With no food or access to do its necessities. AND THERE WAS AN OPTION THAT "they missed" on porpuse."
Pros: "I was bowled over to learn in flight that the lowly steerage (economy) passengers--and everyone else had a selection of 3 complimentary meals! Who does that any more! Unfortunately, the only vegan option ran out just before my seat, but I was still amazed and pleased....and have ordered a vegan meal in advance for my next flight. Incredible! Plus, plenty of room for bags, good video selections, and power at all seats. I love Delta and will fly them more often!"
Pros: "On flight entertainment has improved greatly. There are so many choices to keep you entertained. I forgot how long I was on the plane."
Cons: "Plane food was not good. The crew were not as friendly, almost exhausted. There was one woman who was not sensitive or compassionate to my fellow seat mate. He was an older man who needed extra assistance. From the look of her face she didn't feel like helping him... as simple as helping him pour ice into his cup. Instead I helped my fellow neighbor. She might not feel comfortable helping a senior citizen but don't be so loud or make a face of disgust."
Pros: "aircraft is very clean. faster than imaged. the most impressed thing is it has a variety of entertainment programs."
Pros: "Everything went smoothly."
Cons: "N/A"
Pros: "Comfort and boarding"
Cons: "Delay and food"
Pros: "Everything about the flight was great. We boarded and took off on time. I have no complaints."
Cons: "My seat wouldn't recline at all. I think it was broken. Not the end of the world, but a bit of a bummer as it was an overnight flight."
Pros: "Flight was on time and left and arrived on time."
Cons: "Should offer headphones for free."
Pros: "The new Delta planes have great leg room for tall people even in coach."
Pros: "Delta was smart with boarding early once they realized everyone had cleared security. Flight took off on-time and arrived early. The crew was excellent and exuded energy although it was the end of the day."
Cons: "I ordered a special asian vegetarian meal and it was just plain horrible. I had to settle for the cookie. It's nice that they serve a complimentary meal on the red eye flight but the quality of the food was bad. Entertainment options were also limited although they had some recent box office entries from last year. The leg room also wasn't great but that's expected in economy I guess."
Pros: "Excellent trip. Provided ample food snacks and drinks."
Pros: "Whoa, we flew Coach and had plenty of space! How marvelous to not be packed in; crew and passengers were wonderfully relaxed, and all went well despite turbulence on takeoff and landing. Great daytime flight experience with my toddler grandchild!"
Cons: "I tried to get a seat and it was so hard, i couldn't do an online check in and once at the airport, no one could help me."
Pros: "Painless"
Cons: "Price of food"
Cons: "Boarding took too long - full plane and double seat booking changed 10 minutes early estimate to 20 minutes late"
Pros: "Quick boarding"
Cons: "The delta comport seats were not comfort seats were hardly comfortable and the leg room wasn't worth paying for."
Pros: "On time"
Pros: "I've never seen such a modern and easy to use entertainment system before. All the movies are complimentary."
Cons: "half-broken screen, couldn't access anything on the left side"
Pros: "That it's over"
Cons: "the 1 hour delay, when we arrived we sat for another hour and I missed my international flight"

Wi-Fi didn’t work. Boarding was totally confusing. Guy next to me took more then his area. Constantly touching me pushing on me. Had a bag blocking getting out. Almost fell. Crew didn’t help

Slow boarding in Seville, no chance to check-in online🥺

The flight from Rome to Ams was delayed. The flight from AMS to Moscow was missed. - We spent 2h in a linewaiting for the service desk to rebook the tickets - Then, we spend more than an hour to get the hotel - Then waiting for the shuttle another 30 minutes Unexpectedly poor and slow service. The next working day is ruined with the flight in the middle

Pros: "Crew was great, on time flight, clean plane."
Cons: "Entertainments options were shockingly few. Honestly have not been on a plane recently with so few and limited options of TV series and movies. I was extremely surprised. Wish I had know and I would’ve had more options for my family."
Pros: "Boarding was efficient and the crew were nice."
Cons: "the seating is horrible. it was the tightest seating I've ever experienced."
Cons: "No internet available (2020). For the my previous flight, a month ago, was the same problem."
Pros: "Crew is excellent, polite and personal!"
Cons: "Plane is super old and outdated. Comfort seat is not, comfortable, very tight. TV screen is not good quality, with the old controls on a handset. No touch, no 1/8 inch audio jack (it has the old 3 holes one). Wifi for streaming freezes every other second. Just make a face lift to the plane, everything else is good."
Cons: "Still don’t have my luggage yet"
Cons: "Boarding was chaotic & therefore delayed take off a little Receiving luggage was slow -@ 35 minutes from landing to luggage claim, so actual arrival was considerably later for those meeting me"
Cons: "The flight from Manchester to Amsterdam has been delayed which led insufficient time for me to transfer to HK"
Cons: "Flight 2 hours delayed, started boarding but had to wait on line 10 more minutes on boarding ramp for plane door to be opened, upon landing in Dublin had to wait on tarmac for anther 15 minutes for stairs to arrive and be connected to airplane. Then had to wait another hour for checked luggage...."
Pros: "The crew is really welcoming"
Cons: "The seats are too narrow and a bit too hard"
Pros: "The space at my feet with the chair in front was a bit akward."
Cons: "Not being seated next to small kids. Perhaps they should have a separate section? ;-)"
Pros: "The crew was nice and helpful (our flight was 2h late so they put us on the one before in business class for us not to miss our connection)"
Cons: "A lot of delays, on both flights. We spent twice as much time waiting than flying."
Pros: "Crew were great, food, entertainment, seat and everything else was great as well."
Cons: "The flight was cancelled and had to be rerouted on United Airlines."
Cons: "Turn the lights on early making it hard to sleep"
Pros: "Last year I flew Lufthansa which was my worst experience flying ever. I thought the new standard was so low I would never fly to Europe again. I had heard KLM was good but I felt this was as good as could be expected actually much better. The food was even good."
Cons: "I would have to dream something up."
Pros: "Seat 39A did not recline. The gentleman next to me spread his arms out a bit as he typed on his computer the entire way. So I did not get ANY sleep. Plus he got up at least four times."
Cons: "Except for the man next to me - great!"
Pros: "Snooth and efficiënt with a KLM service"
Cons: "No entertainment"
Pros: "Everything was great! Crew incredible. They acknowledged my wife’s birthday and made her feel special. Food was ultra salubrious. Loved the big screen monitor."
Cons: "No complaints about anything."
Cons: "Food had only vegetarian choices. No charging place and ambiance was noisy"
Pros: "Great food"
Cons: "I paid a top price for my ticket and expect the advertised amenities to work. Upgrade or replacement for entertainment system."
Pros: "The boarding was easy and you didn't have to wait inline for that long"
Cons: "KLM needs to upgrade the entertainment. It was very hard to see the images on the screen. The planes that KLM uses are old and they sure need to be upgraded."
Pros: "Need better quality tvs for such a long flight and better movies There were only 4 Bollywood movies and not the latest ones either"
Pros: "Friendly in-flight personell"
Cons: "Approx. 1 hour delay, which was not the airline's fault (construction on runways)"
Pros: "Nothing really"
Cons: "Flew KLM 27 years ago and the airlines seem to be stuck in the same era. Food is poor quality... Have you recently checked the Gulf carriers."
Pros: "Good Experience"
Cons: "Nothing much"
Cons: "Please Endeavour to put the expiration date on the food served in the flight."
Cons: "Bag was lost"
Pros: "The cabin crew were good. They explained what the arrangements were for the delayed flight connections"
Cons: "The plane wasn't refueled and so was not ready for take off once the passengers were loaded. The plane had a technical problem when it tried the first take off and so it had to be abandoned. This was alarming.."
Pros: "The food was excelent"
Cons: "I have to pay to pay a little more confort"
Pros: "Clean airplane, friendly crew, no rush, nice snacks for a short one hour flight. Just generally a positive experience."
Pros: "Everything"
Cons: "Nothing"
Pros: "The flight was great."
Pros: "Entertainment was good, and crew was very nice and accommodating. Flight was very comfortable and smooth."
Cons: "The food was okay, not that great."
Cons: "Service from airline host Poorly maintained plane Bad food Old entertainment"
Pros: "Crew was very helpful.food"
Cons: "Food was not upto the mark."
Pros: "From pre-boarding, to boarding, to the food, and the attentiveness, everything was top notch! The cleanliness of the plane was only topped by the friendliness of the crew."
Cons: "The flight was marked at almost 11hrs but ended up being only 9...not a negative other than it meant not spending as much time on board!"
Pros: "Of the multiple international airlines I recently flew with, I would have to say KLM was by far the best. Relaxing atmosphere, comfortable seating, great in-flight entertainment, although I have the go-go in-flight data/entertainment plan with t-mobile (highly recommended), the flight included a decent selection of movies, television programs, etc. The food far exceeded typical "airline quality," even for an international flight - and included a fabulous little snack box with locally sourced gourmet and specialty items such as chocolate from Belgium, fine cheeses from France, and crackers from England. Drinks = gratis, and crew was exceptionally attentive and went out of their way to make flight as pleasant as possible."
Cons: "Nothing."
Pros: "I really like the spaciousness, the plug ins and general service"
Cons: "I have a dairy allergy but had no option to prepurchase a dairy free meal. It made for a very unenjoyable flight as I couldn't eat anything they had. What was worse was after I told them of my situation they said they understood and had a meal that would do but there was cheese, yogurt, milk chocolate, etc."
Pros: "Great crew service. Among the best ever."
Pros: "That we didn't crash"
Cons: "Being delayed and missing my connecting flight. No entertainment onboard (for hours and hours)."
Pros: "Staff superb. They even surprised us with an exit row and a gift for my partners birthday! Amazing. Samantha and Dennis also took time to come and personally wish him a happy birthday. A lovely touch. This airline runs like clockwork. They are just great. The sandwich and stoop waffle are nice too."
Cons: "There is a bus to the plane, so that takes a bit of extra time but they are very well organized."
Pros: "Very efficient boarding, fast and professional but warm and friendly. The plane was very clean and quite spacious for a two by two configuration. On time departure and landing and smoothed processing at the other end."
Cons: "Nothing to improve"
Pros: "Same as above"
Pros: "Boarding was very efficient."
Cons: "Limited movie selection. Crew seemed stressed. Gave me wrong meal and then swaped for the right one. I asked for Diet Coke and was given white wine. Food quality was not good."
Pros: "Staff, service"
Cons: "Nothing"
Pros: "Excellent service"
Cons: "Having to pay extra to pick a seat prior to check-in. I didn't, and got a decent seat anyway."
Pros: "Except for my negative comment, a good flight."
Cons: "I paid extra for a window seat, but due to the poor alignment of the seats with the actual windows, I actually sat next to a wall! Nol much to see out of a wall. If KLM are going to charge extra for a window seat, then they should make sure there is a window there! If the seat had actually had a window it would have been an excellent flight."

Efficient flight and the pilots landed well in strong winds. The plane left 45 minutes late, not sure why. Clean plane

It was only a short trip On time and easy

Pros: "Had a fantastic flight and the crew was nice."
Pros: "one of the worst airlines I have traveled on. Will never fly air lingus in my life."
Pros: "Friendly crew Excellent movie selection Soft blankets Clean bathrooms"
Cons: "The “American breakfast burrito” tasted like the cardboard it was warmed up in No email updates sent to check in or enter international traveler information (eg, passport number)."
Pros: "Non stop flight, boarding"
Cons: "Food was terrible and seat comfort is bad"
Pros: "The staff are always lovley"
Cons: "They lost my bags and 5 days later I still don’t have them.. traveling alone with a baby for Christmas.. all my gifts were in that bag so Christmas is a bit of a loss.. I find it way to difficult to get refunded or reimbursed for my loss"
Pros: "The crew was nice."
Cons: "We thought we were flying British Airlines. The seats were extremely uncomfortable. Foodcwss not good"
Cons: "Late boarding and had to wait 20 to 25 min in tge plane before tge doors of the plane finally opened."
Cons: "Had to cancel. Impossible to workout fair flight change for outgoing flight only - caused cancellation and repurchase return leg for no reason but greed, as Aer Lingus did not impose this. After multiple long waiting periods on the phone to work this out no one ever picked up. We will never book through Kayak/JustFly again."
Pros: "Aer Lingus service was good and efficient from check-in to arriving."
Cons: "Little time in Dublin to get to our connecting flight to Lyon. Security check was understaffed with long queues."
Cons: "The chairs are so uncomfortable!"
Cons: "The flight was delayed by two hours. The one of the crew members - I think his name was Gerry - was quite rude and negligent: for example he did not give an infant life vest to our baby saying that it won't be needed..."
Cons: "The flight attendants were helpful enough, but they did not offer as many drinks as I like. Breakfast was only coffee, tea or water. No juice at all."
Pros: "Boarding was smooth. The staff was extremely friendly. The games on the video screen weren't bad."
Cons: "There was a technical problem with the plane at our gate when we landed, so we were on the tarmac for an hour waiting for a gate to open. Video choices were limited, and Internet was extremely overpriced."
Pros: "Staff where unbelievable nice and kind"
Pros: "The crew was great once aboard, the food was well above average for airplane food, the drinks were reasonably priced and the entertainment options were great."
Cons: "Attempting to check in online the day before was a nightmare and after half an hour on two different sites and an hour of speaking to very rude customer service reps for both BA and Aer Lingus, we were told we just had to check in in person. The check-in line opened fifteen minutes late, the woman who checked us in didn't answer our questions because she was busy talking to her friend. Once on the plane the Airbus seats were truly awful and should not hold a person for 10+ hours. The wifi also never worked."
Pros: "Great choice of movies and TV shows."
Cons: "The underseat area for storing carryon is SMALLER than on my last trip in Aer Lingus. My simple backpack which has always fit under would not this time."
Pros: "Cabin crew very professional."
Cons: "Stop making the seats smaller, narrower, and closer together, food was awful."
Cons: "At checkin the crew at Aer Lingus claimed that they could not issue a Gate pass, which is offered by all other airlines at SFO."
Pros: "The seat was comfortable on the newer plane and the in flight entertainment was excellent."
Cons: "The airline features an upgrade yourself bid option that starts at a minimum bid. We went above this and got rejected, only to find there were still open seats. They tried to then upsell is at 4x the cost which makes the entire thing seem terribly dishonest. After calling customer service, they hung up on me. It’s clearly a scam to extract more pricing data from customers."
Pros: "The staff were welcoming and friendly. They kindly reminded us of safety, but also due to me not making up my mind for drinks I asked for a ginger ale later in the flight and the staff were sweet enough to give once they finished what they were doing. They also were good at accommodating when my partner was unsure what food he would like and gave a good suggestion. Thank you, the Sheppard’s pie was delicious."
Cons: "N/a"
Pros: "The seats were more comfortable than flying on a Dreamliner. I like the 2-4-2 layout."
Cons: "Some of the flight attendants were very unprofessional and I could hear them in the back while taxiing for take-off complaining about the job. The food was terrible and was served 3 hours after take-off. Every flight I've taken to Europe has at least had extra water bottles in the back of the plane and this flight had nothing. However, my flight from DUB to SFO was great. The flight attendants were happy, the food was good and they had extra water bottles in the back of the plane for everyone to use. I think the service suffers significantly on flights to Dublin from the US."
Pros: "Great Plane, Fantastic service. Did their best to take care of us. Provided us with vegetarian meals and requested and plenty of drinks, including wine and beer."
Cons: "Boarding a bit disorganized, but this seems to be an issue with most flights."
Cons: "the food was really expensive"
Pros: "Crew was very considerate."
Cons: "Two hour flight delay small aisle/seats."
Pros: "Staff was nice."
Cons: "Food and drink service were very bad. Not enough water throughout the flight. And that is what keeps us healthy in long oversees flights. They ran out of bottled water. No decent healthy snack choices, just airline pretzels. Very sub par for an internatiinal flight!"
Pros: "no delays, comfortable seats"
Cons: "The flight attendants went right past us never asking if we wanted anything. They served the people to our right and in front of us. Mystifying."
Pros: "Better not serve this burrito who does not look like food if you read the ingredients."
Cons: "The seat was to narrow once the person in front of me recline her sit. Luckily the plane was not full and was able to seat somewhere else."
Pros: "Flying overnight across the U.S., and then the Atlantic, to Dublin would have been very difficult if not for the accommodations and service provided by Aer Lingus. The reception was warm and comfortable. The in-flight food and service was perfect. The environment was conducive to sleeping during this red eye flight."
Cons: "I have no complaints, to be honest. The flight attendants were so welcoming and accommodating to every request. They were efficient and quick to respond to my questions and requests."
Pros: "Prompt Rebooking. The new schedule was better the original schedule with fewer connections."
Cons: "My original flights from Dublin to London and London to Munich were cancelled. The booking agency Webjet did not inform me about the cancellation. I noticed changes to my schedule three days before the flight and requested a rebooking. The entire leg to Munich was rebooked by Webjet but again I had to call and ask for an update since they don't issue a second round of confirmation emails."
Cons: "One of the on flight crew members was extremely rude, ignoring repeated request for coffee - skipping my husband when she was offering routinely in order, didn't respond to several calls after she skipped then gave him water, acted annoyed when he reiterated he wanted coffee like everyone else. Also insisted my sleeping 7 yr old upright his chair for beverage service when everyone around us had their seat reclined(the people around us were all Caucasian btw) and she didn't seem to feel the need to remind them."
Pros: "The crew was pleasant and accommodating to me, my wife, our 3-year-old and 1-year-old for both legs. The planes were in good shape and everything was on time. The balthrooms were clean and felt spacious. I didn't eat the dinner because we ate a large dinner before the long flight. I did tasted it and it was good. The selections of movies was also very good."
Cons: "Thw system they use for in flight entertainment was a little glitchy."
Cons: "Flight was delayed over 2 hours. They also lost my luggage. Very poor and rude customer service."
Pros: "Dublin airport easy to transfer Price was top I did not eat the lunch"
Cons: "No snacks nor drinks offered at night. Breakfast was meager."
Cons: "I made my reservations for British Airways and the flight was by Aer Lingus."
Pros: "Comfort. Missed connection and reassigned to next flight easily. Short delay."
Cons: "Luggage was delayed and delivered 24+ hours later to our hotel."
Pros: "Fantastic flight service"
Cons: "Lost luggage for three days. Had to buy clothing. Staff seemed dismissive when I went in a search on the third day back to the EDI airport. They said they didn't have any information about it and that it was probably in Dublin. Later it showed up at my hotel with no call or notification. Not acceptable. Probably will avoid Aer Lingus in the future."
Cons: "The food was terrible, could not consume."
Pros: "Friendliness"
Cons: "Entertainment options VERY limited! Plane was freezing the entire flight."
Cons: "Inability to choose seats. Flight attendants come around infrequently and so quickly you can't even ask for a water."
Cons: "Shopping was not avail on the plane"
Cons: "It would have been great but my TV was not working properly and had intermittent sound. The flight attendants tried to fixit to no avail."
Cons: "Entertainment system old and slow"
Cons: "There wasn't any notification prior to booking process, with regards the need to get visa from the airport where I should be transiting for 2 hours only. After I booked and paid for nonrefundable, unchangeable, uncancellable ticket, I got an email asking me to get a visa in order to be able to transit for only two hours in Toronto airport. The visa takes at least 2 weeks, and my travel date was only few days ahead!. The rough lady in air Canada, plus the bad service and advise by the travel agent who advised not to take any action as it is only 2 hrs transiting and I won't be in trouble, all of that makes me not to recommend anyone to use your weird website. I had to stay 20hrs in the airport to book for another flight."
Pros: "Both British airline and Aer Lingus service was 5star. and kayak did its job they made reservation super easy."
Pros: "Crew sorted out a veggie meal even though the request from priceline did not get through."
Cons: "Audio on the TV/film system was muffled, could hardly hear dialogue. No subtitles either. Gave up. Not enough legroom, too cramped for long haul."
Pros: "Crew brought around plenty of water, this was in marked contrast to my last Aer Lingus flight where nothing was offered from one hour to the next"
Cons: "I injured my leg before flying and Aer Lingus were very unhelpful and unsupportive. They had promised to speak to my doctor and then didn't, I was promised assistance in the airports which never materialised and when I checked in I was promised a spare seat next to me to allow me to stretch the leg out. This was taken away from me once I was on the plane and I had little space and comfort. I wouldn't fly Aer Lingus again unless there was no choice."

Service on board

It was great

The de-planing process could have been better in Buenos Aires - it took a long time before the aero bridge was connected - not the fault of Air France..

The cabin crew was friendly. But boarding takes forever and the flight gad long delays on both inbound and outbound flight

Pros: "Clean plane , good crew ,"
Cons: "they didn't load my baggage from flight 1 to 2"
Pros: "I like the crew and their service, the food was amazing speacially the vanilla cheese cake desert was on point, loved it. I loved the “my flight “interaction on the screen and the different view of the plane, cockpit view, left, right etc.. amazing feature."
Cons: "The seat could have been much better as far as reclining and space. Overall I loved the flight."
Pros: "Good aircraft, good service, on time, eventless"
Cons: "There are two types of foot-rests, both are a nuisance for people with long legs. The one popping up from below one's seat is extremely hard to put back in place. The metallic one folding down from under the seat in front cannot be secured back and is always in the way if the passenger needs to stretch his/her legs. This seems to be a new appliance, and I jut wish they would do away with it altogether. More is not necessarily better."
Pros: "I"
Pros: "The crew was perfect"
Cons: "No wi fi on the plane."
Pros: "Crew were very good."
Cons: "No vegan food available."
Pros: "The crew"
Cons: "The time. The flight was late for 1 hour. I miss everything and also I get very late to our Airbnb and I was with my family and child"
Pros: "Exit row seat had much more space for legs, very much worth the upcharge for this seat."
Cons: "Cabin temperature was very cool for me. Never used a blanket on an international flight before, and used a blanke on this whole 9 hour flight. Maybe a function of the seat location? Not sure but I was cold."
Cons: "We didn’t travel to Detroit... we were re-routed 3 times and our luggage is lost, some really helpful ppl along the way (thankfully) and some really crummy ppl too... no in between... still not to our destination"
Pros: "The flight departed on time and arrived early. The crew were all courteous and kind even to the man who was sitting next to me who seemed quite demanding."
Cons: "I am small but the seats seemed a bit too tight. The plane itself seemed a bit outdated."
Pros: "Yes"
Cons: "Everything very good"
Pros: "Multiple crew members paid constant helpful attention to my mother (88yrs of age) during boarding, deboarding and throughout the entire flight. Thank you!"
Pros: "The crew was excellent."
Cons: "The snacks that were handed out prior to landing were not very good and it looked as though a lot of people in our section felt the same way. Also, there were a lot of empty seats in the comfort and premium sections, but non of our gold medallions were offered an upgrade."
Pros: "Friendly attendants, entertainment variety"
Cons: "Comfort, food could have been better."
Cons: "If you have to change planes and Paris is your middle person. Leave at least 2-3 in between the two flights otherwise you might not make it."
Cons: "The food was mediocre. Flying La Compagnie in the past was a much better food experience."
Pros: "Very little"
Cons: "Flight was very crowded. Flight crew kept bumping into my seat and never apologized"
Pros: "The CDG airport is very bad in terms of finding your connections, the flight to CDG from LAX had a very old entertainment system and was hard to use."
Pros: "Really liked the new touch screens (with very good responsiveness). Also liked the food selection (the champagne was nice, so was the menu we were given)."
Cons: "I didn't get to board, ended up spending $2,400.00 over and above the $980.00 that I spent booking the initial ticket. I was not informed when I booked the ticket that when you transit through 2 schengen countries, you need a transit document. I was informed about it at then airport. Not only did I miss my flight, I had to book for the next day at a outrageous price. SUPER BAD CUSTOMER SERVICE...BOTH KAYAK and PRICELINE. Will never recommend you guys to anyone."
Cons: "Being in the middle of the 4 seats with guys on both sides. They tend to restrict the space by using the arm rests."
Pros: "Cheap ticket"
Cons: "The fact that you cheapskates don't allow credit or refund is downright usury. I didn't take that flight because of medical issues that caused me to cancel my trip 2 weeks in advance. I pleaded with you to be able to take a credit, to no avail. You lost a customer."
Pros: "En deux mots, tout était médiocre, avion, « nourriture » (si on appeler ça comme ça) même les hôtesses travaillaient avec une sale gueule.. Très déçu d’Air France"
Cons: "Le capitain et l’aterrisage"
Pros: "Great service, decent food"
Cons: "There was no WiFi on the plane"
Pros: "The food was okay and the staff were friendly."
Cons: "My seat and several others around me were broken so that they would fall all the way back if we leaned back at all. The entertainment system kept crashing and forgetting what shows everyone on board we’re watching. There were no air vents to control. The games crashed constantly. The usb hubs didn’t work."
Pros: "Great food (Economy class). Good Service"
Cons: "Not enough bathrooms on Economy class area due to aircraft design."
Pros: "Enjoyed my food, especially tasty for airplan fare!"
Cons: "Not enough leg room"
Pros: "I like traveling with AirFrance in general."
Cons: "Terminal too far to go to loggage, walking about more than two miles after a long trip is not very easy AirFrance should have a better terminal at Charles-de-Gaulle!!! Have some missing stuff in my luggage!!!!"
Pros: "We got to the desk to check in and there was one person being served in front of us. He finished with him, turned and left the area through the dooor. No one came to help us for 15 minutes. Then they came out to answer the phone and said we were 10 minutes past the cut off and we could not fly."
Cons: "Staff just walked away while we were in line, the rudeness and mean attitude, they blamed us for being too late after ignoring us and made us late, they didn't offer an alternative flight until we asked. Overall, horrible customer service. Never been treated so rudely by people in the airlines industry in my entire 42 years of flying!"
Pros: "Average"
Cons: "I leave my jacket in the hanger when I get off the airplane I realized that they didn’t gave it to me. I inmeadiatly tey to go back but I couldn’t I went to the counter and they said that there was noting on the plane !"
Pros: "The service was very professional."
Cons: "Everything went well."
Pros: "Only the cabin crew was good."
Cons: "It was the worst flight that I ever had, the seats are extremely uncomfortable, no TV, the food was terrible."
Pros: "Plus seat was good. On board crew was nice."
Cons: "Another Air France company, with their motto: We Don't Care. Ground staff was rude, no good food onboard and have to pay for it. Entertainment is your device, but you can't download the app to use it."
Pros: "The crew, the service, the food and beverages"
Cons: "The 3 hours delay"
Pros: "Crew very professional and nice food Boarding process well organized"
Cons: "Poor seat comfort in business class and no entertainment for a flight lasting more than 1h"
Pros: "The price 50€ cheaper than the other operators. Quick flight. Kind crew."

Cons: "It was delayed"
Pros: "the food"
Cons: "no room for legs"
Pros: "Good on a short flight"
Cons: "Paying for carry on due to weight limit. First time this ever happened!"
Pros: "Great people"
Cons: "It was an hour late"
Pros: "The food was good."
Cons: "I feel comfortable flying when I can see out the window so don't force me to close my window shade.The flight attendants kept forcing me to close my shade. Also new planes would be nice. Sick of flying on outdated technology."
Pros: "The food was good, the staff was very friendly and very nice,"
Cons: "The seat configuration in economy is unacceptable, the leg room is terrible and overall a very uncomfortable flight of more than 7 hours"
Pros: "Wheel chair service at LAX is run by the airport. Their priority is to get you to your flight, not to a VIP room regardless of how early you check in."
Pros: "Space"
Cons: "Couldn't adjust the seat and the cushion wasn't comfortable neither seat or back. The bottom back was like a board across the bottom and hurts."
Pros: "Efficient boarding. Interesting hot food. Entertainment variety very good."
Cons: "Business class seats hard. Did not flatten out for sleep."
Pros: "Good food. Although no Cappucino as in AF from Sanfransisco to Paris."
Cons: "No entertainment at al. Specifically, I could not lean my seat b/c of a mom with a baby behind me..."
