Pros: "Being on time"
Cons: "Nothing you guys did great thank you so much."
Pros: "Crew are always top notch, free drinks are readily available and entertainment system is great."
Cons: "The food portions and quality have definitely declined over the years sadly, as carriers cut costs no doubt."
Pros: "Amazing"
Cons: "Nothing really"
Pros: "I travelled on economy delight, flight was fully packed, yet it felt spacious and comfortable. Lightning was great. Food was yummy! And pilots gave us updates on air travel, and if there were any delays etc."
Cons: "Nothing. Had a great trip!"
Pros: "Amazing crew, excellent drinks and decent food. Very comfortable seat"
Cons: "Everything was great"
Pros: "Crew was great !!!"
Cons: "Seating in upper class is uncomfortable and bedding is not fresh."
Pros: "The seating in upper class is unconventional and uncomfortable."
Cons: "Reconfigure seating in upper class. We will no longer be customers for that reason alone.."
Pros: "Although there were delays they kept us informed on a regular basis as to what to expect and seemed genuinely apologetic for any inconveniences. Boarding and deplaning were smooth and efficient. I really appreciated that there was no charge for checking a bag. I am certain that contributes to the ease of everyone getting on and off the plane. Our bags arrived at baggage claim about the same time we got there. I would definitely fly with Virgin Atlantic again."
Pros: "crew was nice"
Cons: "First time flying with a partner through Delta, so they stuck us on a Virgin Atlantic flight meaning I didn't get my free Delta check in bag (a fee of $60 each way) when I have gotten it every other flight I have ever taken with them. It was also 2 whole hours late in boarding."
Cons: "Nothing"
Cons: "They have to uptade the airplanes"
Pros: "The airplane was quiet My seat did not recline, but was seated in a different place where the seat reclined Bathrooms were clean and plenty"
Cons: "The remote controls for the entertainment system That you can’t reach the vents when you have to be buckled"
Pros: "- Presence of entire box sets of some TV shows was a nice touch that I made good use of."
Cons: "- EVERY damn movie is prefaced by 4 minutes of ads. - The touchscreens (at least in economy) are slow resistive screens that are horrible for fine control gestures (like slightly changing the volume or position)"
Pros: "Staff. Very couteous.polite. friendly."
Cons: "Good.entertainment choices."
Pros: "The ground staff was on top of it and the boarding process was smooth, but the cabin crew was brilliant. I’ve never had such pleasant service on a western airline. Well done. Entertainment system is top-notch, and the food was acceptable."
Cons: "The booking process and paying for luggage is disappointing. Plus, I paid a $90 upgrade and just moved up two rows in the same section. Sneaky."
Pros: "Crew were great"
Cons: "Uncomfortable to sit for eight hours"
Pros: "I thought the airline amenities were excellent and it was a seamless process getting on the flight. The flight attendants were very warm and accommodating. I felt immediately welcome as soon as I got on the flight. I liked that they were playful with my son and engaged him."
Cons: "Nothing. We did leave a piece of luggage on the plane so hoping that things turn out okay."
Pros: "Nothing"
Cons: "Everything incl customer service at the airport"
Pros: "2 bags each 23 kilogram each total 46"
Cons: "Coffee. I don't know what it was but the worst coffee I have ever had and I tried it 3 times"
Pros: "Fast boarding and nice staff. Food selection was ok"
Cons: "One item missing from menu (unavailable). Issues with entertainment system. Bathrooms lacked moisturiser which is always very helpful on long flights where the air is dry"
Pros: "The crew and food were excellent. A little more space between seats would be appreciated. The entertainment equipment was not intuitive or easy to operate. I still feel the airline did a great job getting us to London on-time and a pleasant flight."
Cons: "I had to be rebooked on a later flight due to weather in London; this was obviously not the airline's fault. Because I took a later flight I missed my connection in London."
Pros: "love the lounge and easy check in and boarding, great attendants and smooth trip"
Cons: "would be nice if lounge was open earlier - arrived for 8:30am flight and had to wait around in freezing cold terminal with no coffee for an hour"
Pros: "Flew virgin after long time and kind of disappointment with comfortable seats. seats space is tight and legs space as well with some box under the seat."
Cons: "seat comfortable and let space"
Pros: "Francesca was the flight attende t that I had most the most interactions with was very friendly and warm."
Pros: "Safety. Service."
Cons: "Lavatory was icky and other passengers messy."
Cons: "Food was hard and little stale."
Cons: "Flight was cancelled ."
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: "My first time flying to Europe! I love the service from the attendants but my seat mate made it uncomfortable to seat in my seat. Overall great experience"
Pros: "Smooth flight"
Cons: "My economy window seat was just too cramped for a big guy on a nine hour flight"
Pros: "I felt that they were very thoughtful about the fact that it was a long flight. We got two small meals, which was perfect, and even a little gift bag with a sleep mask and toothbrush and such in it. These were just a couple of the many nice touches included in the flight."
Cons: "Very small quibble: the screen resolution, or maybe the contrast, of the personal video players was not so great. This was fine in most cases, but it meant I could not watch videos that had subtitles. Not a big deal but possibly worth fixing. Thanks"
Pros: "The flight was late but the pilots made up most of the time"
Cons: "Uncomfortable seats"
Pros: "first time I flew VirginAtlantic. Heard so many good things about it. It fact even our Uber driver was praising the airline on our way to the airport. But once onboard: - poor food (I mean 'survival kit' style) - entertainment station was not working - games feel like 20 years old - design (heavy red) now looks dated and suffocating - hostesses are more focused on their hairstyle than their customers"
Cons: "Back to Air France next time!"
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: "From check in to landing in London, the gracious, helpful crew impressed us with their attitude and service"
Cons: "Sound didn't work on some of the entertainment choices"
Pros: "Nothing - except the toilets with tabs for lifting the seat & adjustable headrest. They forgot to load our toiletries overnight pack too!"
Cons: "The 787 has vastly inadequate Economy toilets - ONLY 4! For 200 passengers. Inadequate lighting for,boarding, unable to activate reading lights until AFTER TAKEOFF = groping in semi darkness, BAD! No window blinds = woken up by blazing sun in middle of 11 hr night flight, even with sleeping pills my sleep was wrecked, even with eyemask. Passengers penned in on narrow aisles by trolleys, unable to walk around plane & risk of DVT. Passengers disempowered by restricted space, lighting, mobility. I want more control over my personal mobility &, lighting. Horrible headsets (bring my own). This flight departed 2.5 HRs LATE from JHB & the crew & cavin service was SLOW. NO requested second cup of tea brought - I waited 20 mins & climbed over trolleys to get another one, even though it was requested of cabin crew. Do they just ignore us? Or forget?"
Pros: "airline staff was helpful, friendly and accommodating from ticket check in to flight staff."
Pros: "They were were very kind and helpful to all passengers"
Pros: "Very good on board services and nice crew"
Cons: "At boarding in Atlanta, they only checked in 1 of my 3 luggages to my final destination, the 2 others are lost..."
Pros: "The space you have with your legs is sufficient and the chairs are very comfortable. The food was really nice. I enjoyed the trip, although it was a long one."
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 .."
Pros: "Mostly everything was fine."
Cons: "Not really anything particularly that I didn't like."
Pros: "Professionalism value of service"
Cons: "let me think...."
Pros: "There were lots of choices of movies. The flight was only half full, so I got two seats together to stretch out."
Cons: "The cups for water and juice were very small."
Pros: "Very attentive and friendly crew! The plane was nice and clean, nice purple tinted lights. They served us plenty of complementary meals, snacks, mints and drinks. The in flight entertainment was the best I've seen yet: movies, tv, music, games, all recent and easy to use. We will definitely fly Virgin Atlantic again!"
Pros: "The meals were very small and not very tasty. Economy appears to have lost staff as it takes the entire flight to get a drink and dinner, the feeling you get is that you should just get on board and then sit quietly for 7 hours and not ask for anything. The entertainment does not have a very large selection and if you fly regularly does not seem to update very often."
Pros: "The ground staff at Delhi was very helpful in giving us a new flight ticket for the next day for free eventhough they maintained that it was actually Air India's responsibility."
Pros: "Having partied until 6am for New Years I was grateful for a bed on the flight home! Fantastic crew, planes and overall service!"
Cons: "Wish the arrivals lounge was open for flights arriving in the afternoon."
Pros: "Courteous flight attendants; good cockpit crew"
Cons: "Delays kept getting longer. On the plane for three hours before takeoff. Seat very uncomfortable -- reclining function didn't work, and no extra space -- and had paid extra for a "comfort" seat."
Pros: "Crew brilliant but seat very tight"
Cons: "Boarding procedure slow and hectic"
Cons: "Seats can be better."
Cons: "Security in Frankfurt - long lines"
Pros: "Nothing"
Cons: "Everything"
Cons: "Flight late more than 3-4 hours on Frankfurt. So upset. I will never and ever try with Frankfurt again. I bought shortest way ticket to pay more money but unfortunately flight late about 3-4 hours. Money trap. I would love to have another free flight or I will post the tickets on facebook, Twitter and etc... To make a terrible flight reputation."
Pros: "Comfortable seats"
Cons: "Meals and entertainment"
Pros: "Very fast and cheap flight."
Cons: "Seats were extremely uncomfortable. Boarding was very chaotic."
Pros: "It was long flight but everything was just right. Will use this company again."
Cons: "Food was OK, could have been better."
Pros: "Good leg room in aircraft and comfortable seating."
Cons: "My checkedin baggage did not reach the final destination and was delayed by 24 hours. Further, when my baggage did reach, one suitcase was damaged. Did not expect this from Luftansa."
Cons: "The flight never took off after 3 hours on board on the tarmac. There was poor communication from the staff at the airport and no compensation from Lufthansa."
Pros: "best take off and landing I’ve ever experienced. 2 meals for an 8 hour flight and all the red wine I could drink!"
Cons: "Delay and food was bad"
Pros: "Flight delayed leaving, but arrived on time"
Cons: "Food was so-so. Didn’t know wireless headphones were not compatible with inflight movies. Flight attendants seemed grumpy"
Pros: "Nothing"
Cons: "I have been transatlantic for forty years on various carriers. Without a doubt this was my worst flying experience ever."
Pros: "It was run by UA, better seats then Austrian or Lufthansa in Economy. On time. Very efficient."
Cons: "Could not choose seats online,"
Pros: "Flight was on time, food good. Even the movie selection was great, but ... (see what I didn't like)"
Cons: "Entertainment (sound) in seat 14K didn't work, despite 1 reboot. Please fix."
Pros: "Everything that happened during the flight was fine. The service, the flight itself, and the landing – which was excellent."
Cons: "On the ground, neither the staff nor the signage made it clear exactly where to check in. I was sent to the Lufthansa counter, which didn’t open until 11:30, when I should have gone to the United counter. An hour of my time was wasted, which almost resulted in my missing the one-hour before take-off check-in deadline. The only reason I didn’t miss the deadline was because the flight was late taking off."
Cons: "Flight was delayed twice."
Pros: "I like the Aircaraft - A350-900 and service"
Cons: "You cancelled my flight & I lost a whole day of mt trip!"
Pros: "Great service. Friendly and accommodating."
Cons: "I don’t like the configuration of the biz class seats. They are in a row vs in pods. Not as private as other configurations."
Pros: "movie selection"
Cons: "I missed my lufthanza connection"
Pros: "Flight staff were kind and friendly"
Cons: "I could not push my seat back and the man in front of me pushed his back leaving me very little room"
Pros: "The bathroom downstairs"
Cons: "Late arrival inMunich, rush to connection and my luggage didn’t make it"
Pros: "Visa for India was not checked in Denver. Landed in Frankfurt and discovered that the visa was expired. Stuck in Frankfurt for 3 nights until new visa was issued. No babes the entire time I was in Germany. Arrived in Mumbai after paying the $350 US change fee and no bags. Bags finally arrived on Monday at 9AM Without clothes, toiletries and medications for 6 nights. Now I am delayed and will probably have to pay rebuke and fare change to extend my stay here."
Pros: "1 hor 30 minutes instead of 2 hours 15"
Cons: "Worst food ever, and zero entertainment"
Pros: "I liked that if I asked for something the crew would get to me rapidly. Extra leg room."
Cons: "Boarding process: just a lot of confusion. Inflight crew service poor: the was no time to have any brain reaction when they would pass by with coffee or anything...and when I asked for coffee the answer for a gentlemen of the crew was: coffee already passed by. Really!!?? Make sure that +$1200 are spent well. Rude or inattentive crew members shouldn’t be on flights that are that long...I had to nsist to have a miserable cup of coffee. Movie selection was poor. USB port didn’t work. Shame on you!"
Pros: "Friendly crew"
Cons: "Plane loaded late then waited on the tarmac, arrived an hour later than scheduled time. This has happened to me on every one of the ten Lufthansa flights I have been on. Apparently they don't know what it is to be on-time."
Pros: "At least Lufthansa has a little bit more leg room."
Cons: "None of the flights arrived on schedule. That caused other problems. Overall the trip was terrible. Not sure if I will fly lufthansa again nor recommen."
Pros: "The best in-flight service I have ever had on the Lufthansa flight from Denver to Munic!"
Cons: "Couldn't reserve a seat, even 24 hours in advance because web checkin was turned off. Ended up in the middle of the middle on both directions."
Pros: "Gave us snacks when flight was delayed"
Cons: "Flight was delayed Entertainment app didn't work"
Pros: "Great crew service"
Pros: "Timely."
Cons: "Seats are small, no entertainment, food was below average."
Pros: "the crew are exellent"
Pros: "Comfort"
Cons: "Was a short flight , so really I don't have any negative impression"
Cons: "Entertainment options were not too good. The flight should have more American sitcoms and more Hindi options."
Pros: "The overall feeling of this flight was 'relaxed'...after getting over the fact, that this was a huge (two story) airplane. Short flight from Denver to Frankfurt...only 8 hours:)"
Cons: "I would have loved to be offered eye shades and ear plus, since most passengers watched movies and i wanted to sleep:)."
Pros: "787 seat spacing (a UA plane, not LH)"
Cons: "Took first available train , arr. Freising at 9:50. Arrived at Terminal 2 by bus ca. 10:25. I am handicapped and a slow walker, so I got to departure floor ca. `10:40. Waited in line at self-serve check-in; found out that it does not have ability to process numbers (for US address). Attendant was not helpful and nasty. She told me me to go to the regular check-in line, where I waited another 45 minutes. None of the 3 "help" personnel standing around when approached managed to tell me that there was a special counter for handicapped persons. The one at the express self-check-in refused to give me her lasst name or any form of ID (first name Sophia). After waiting an additional 15 minutes for a wheelchair, I was deposited in a waiting area, where a second wheelchair arrived after another long wait. Told me I might not make the plan (I did). Overall a very unpleasant and nasty experience. With the exception of the very nice lady (Mrs. Ilser?? ) who checked in my luggage, none of the other 3 persons at the express and regular check-in spoke decent German or English, and none was helpful (Go there, wait!!!) Barely made the plane in MUC, Heathrow turned out much better than the touted German efficiency. Please forward to Lufthansa customer relations. Dr. W. Hartwig"
Pros: "Flight was on time comfortable good crew clean and upbeat"
Cons: "Boarding"
Pros: "Great service, crew attentiveness and economy comfort. Movie and music selection was good."
Cons: "Slightly larger food portion"
Pros: "Good flight good seats smooth ride."
Cons: "Boarding was not organized."
Pros: "Good job keeping up on food and beverages. Entertainment was great. It was a long flight but was manageable with great service"
Pros: "United is a good partner to Lufthansa. I like United. It was a quick flight, but a good one."
Pros: "Pleasant crew."
Cons: "Annoying kids in seats behind us :( Not enough leg room for someone over 6 feet tall."
Pros: "The crew and in flight experience were excellent."
Cons: "Both Lufthansa and United's boarding announcements fail to account for passengers' impatience and neglect of boarding group procedure. Lufthansa doesn't clearly identify when un-prioritized groups should begin to board. United should make clear that unspecified group members attempting to board prematurely will be held to the back of the queue for their appropriate group."
Pros: "The flight was on-time!"
Cons: "The food was mediocre."
Cons: "Rude (American) passengers not keeping the "curtain down", when it was time to rest, and being very chatty. Also baby crying, but this is inevitable, it happened to all of us, when we had small babies."
Cons: "Food options"
Pros: "The Icelandic movie selection with English subtitles was nice."
Cons: "Icelandair is not great for international flights. No free food or booze."
Pros: "Entertainment was pretty good."
Cons: "Seats seemed small for average size person. 2 flights on my 3 leg journey were late departing and arriving. No missed connections but it was close."
Pros: "Good crew and a smooth flight"
Cons: "Loudspeaker system lousy, could not hear any announcement from cocpit nor cabin crew about safety or flight progress"
Pros: "Crew was polite"
Cons: "Boarding was late"
Pros: "Connection gate in Rekyaveck wa. Sry convenient"
Cons: "Seat comfort for a new plane was terrible"
Cons: "I never took my flight, the customer service to cancelling my ticket would have been a huge help."
Pros: "Reasonable fares. Good baggage accommodations. Denver to Iceland direct. Nice flight staff. The flight attendant pointed out the people who were awake the northern lights which was definitely the highlight of my trip!"
Cons: "Seats small. Surprised no meals unless purchased. But didn’t matter too much I ate before the flight left. And it was nice to have something to purchase if needed. It was confusing where I could purchase my baggage ahead of the me while checking in online so I just paid for it once I got to the airport."
Cons: "Very limited food choice."
Pros: "Nice flight. Empty seat between the two of us! Arrived earlier than expected."
Cons: "Nothing."
Cons: "Seats in business class are uncomfortable. Passenger loading was abyssmal: no advantage -rather a disadvantage - to "boarding" first, the trurh is that we had to wait standing for a bus."
Pros: "The overall mediocre entertainment was the best part."
Cons: "Bag drop took 75 minutes waiting in a line with minimal signage. The middle seat is not designed to accommodate a small backpack, let alone, my tiny, size 5 feet. There are no snacks provided (7.5 hour flight) and NO refills on WATER!!"
Cons: "Baby in front of me and baby next to me took turns screaming during the entire trip."
Pros: "The price."
Cons: "The room between rows and the very narrow seats. I’m a tiny person and I barely fit in the seat. I can’t imagine an average sized person managing for a long flight."
Cons: "Technical difficulties boarding and unboarding. Which made it a rush to have to go back through customs in Reykjavik to board the next plane"
Pros: "flight attendants great and accommodating den - kef"
Cons: "it was a little toasty on the plane"
Pros: "Excellent on board entertainment."
Cons: "No meal on board for an international flight."
Pros: "Clean. Good service. Just way better than most domestic flights in recent memory."
Pros: "I was able to get a good seat just behind the first class section."
Cons: "There's no free food . They should give at least snacks like sandwiches, peanuts, etc."
Pros: "the route and speed of transfer to the next flight"
Cons: "Poor range of foods, limited supply available by the time the crew gets to you. Tea was made in a coffee pot and tastes horrible."
Pros: "Kids get activities and a special meal box. Flight attendants were helpful in making our row restful for my kids to sleep. Nicer flight than I expected."
Cons: "Nothing - would fly again!"
Pros: "Seating was adequate and comfortable enough."
Cons: "Flight was delayed, but not shown as late on monitors. I only knew because I checked online. Once on board the plane, I heard that the incoming plane had been delayed, but there was never any announcement made prior to that. Surprised that I had to pay for food on flight, given the lateness and inconvenience of delay, plus what was available was very expensive."
Cons: "3 hour delay from Denver translated into a 6 hour delay to my final destination. Food on board is expensive, even when other airlines offer food in their ticket prices. Very likely will not fly on Iceland Air again."
Pros: "The crew was courteous, and polite. Vwry helpful, and the flight was extremely fun, ibe never seen so much in my life, and being able to follow the flight path was my favorite."
Cons: "Because i didnt have an aisle seat, sometimes they seemed to forget I might habe rubbish, but overall they were always walking by to assist. Still a positive."
Pros: "The flight was quiet and I was able to get sleep on the transatlantic leg. Passport control at KEF was quick and plenty of nice places to wait during my layover which had been extended thanks to anweather delay.frie"
Cons: "Hard to rate food when it's for purchase and I didn't consume any. No drinking fountains at KEF Food for purchase only"
Pros: "Great in-flight music and movies. Top notch. Friendly and quick service too."
Cons: "Airport in Reykjavik was awful. They had 5 or 6 flights leaving at the same time out of the same wing and so there were crowds of people standing around with no direction..."
Pros: "On board entertainment was good (i.e., movies, shows, etc.)"
Cons: "No food was served."
Pros: "We really loved the price and the service was fine. Having the stopover in Iceland on our way to England was a treat and the schedule was fine."
Cons: "Bugged me that they charged for a meal on an intercontinental flight."
Cons: "The flight from Denver was delayed an hour. Our connecting flight in Iceland DID NOT WAIT for the seven of us. We were supposed to be in Geneva 3 hrs later but waited in iceland 7 hrs the sent to Frankfort Germany before being flown to Geneva 24 hrs after departing Denver. We had two toddlers with us. There were flights on other airlines available without delay, Icelandair had no compassion."
Cons: "First time I have flown on the international flight and there was no food"
Cons: "My wife's bag did not make the plane from KEF to AMS. Still hasn't arrived 30 hours later."
Cons: "Depending on the seat you get (aisle, middle, or window) you either can or cannot fit anything under the seat in front of you. Each seat has different space. What I usually take wouldn't fit anywhere but the window. The middle seat space is USELESS as there is something installed that MAY give you about 6 inches from floor to it. The aisle seat's forward under space is a cube shape, so typical carry-ons won't fit there either. As I slept the whole way to Reykyavik, I don't know much about the service. The under seat space may lead me to not booking Icelandair again."
Pros: "Icelandair is great because your connection waits for you even if your flight is late."
Pros: "The crew was nice and it was nice that they gave my 8 year old son an activity bag and free meals. The entertainment center was great. The flight was on time and everything seemed to run smoothly."
Cons: "It felt like a domestic flight in that there wasn't a lot of extra space and we had to pay for everything (food, snacks, headphones, wifi) aside from soft drinks."
Pros: "On time"
Cons: "No food or drink amenities"
Cons: "No blankets and the temp in the plane was freezing. Possibly this is only for this specific flight, very little info on delay and almost no info on what was going on."
Pros: "Nice leg room. Nice crew."
Cons: "Seat very uncomfortable; rear end very sore. TV unit kept coming back on after being shut off."
Pros: "Entertainment options, crew was very polite and helpful"
Cons: "Any overnight flight should provide a meal or better meal options to buy"
Pros: "The crew were polite."
Cons: "Reykjavik airport is disorganized and crowded. There aren't enough seats for passengers. People were sitting on the floor. There is no orderly boarding of the flights. There are no drinking fountains for refilling water bottles. Everything is for sale, including water. Never again."
Pros: "The crew was quick and kept us informed; the iPads were a pleasant surprise and a nice addition to a flight"
Cons: "No communication with passengers regarding delayed boarding and absolutely NO announcements to board. Everyone lined up and just waited until they started letting us through, so it didn't even matter what seat you got, it all depended on how close you were to the front of the line. Completely ridiculous. Keflavik Airport was too congested with no consideration given to pedestrian traffic while trying to board an entire plane. Massive jams."
Pros: "Pillows and blankets. Lovely crew"
Pros: "I enjoyed everything about my experience with Icelandair. I am going to be flying into London through them for now on and hopefully on an annual basis!"
Pros: "Was offered a seat so we weren't seated 3 across on our side of the aircraft"
Cons: "I preordered a meal that they didn't get from the caterer and none available on board. Waiting area for flight had no seats."
Cons: "The movies were all old, no new variety. They refused to let us take our bag on to the plane even though it fit in their provided sample bin and made us check it at the gate. There was plenty of room on the plane bins and several bigger backpacks than our small duffle bag! This caused us a lot of extra time spent upon arrival waiting for it"
Cons: "you cancelled my flight, no more Iceland air for us, we had to cancel our entire vacation."
Cons: "No food served in economy. Bought a tapas box for 11 euro that was not worth even half that."
Pros: "Flight nice, easy, crew good. Good seats. nothing wrong really"
Cons: "I didnt' realize there was no food at all! Oh well, I guess that's how I got such a cheap fare."
Pros: "Service was good, seat was comfortable."
Cons: "Having to buy a meal on a seven-hour flight is surprising to me."
Pros: "I appreciated the fact that we were able to fly out despite there being a major snow storm and closed airport just hours before our takeoff. We also appreciated being able to switch our connection flight fairly easily once we knew we would be delayed. The staff was very kind and since we had a longer layover in Keflavik, we were very grateful for the food vouchers to used in the airport while we waited."
Cons: "The airline wouldn't make a decision about whether or not the plane would be flying out on time or be delayed until about an hour before our original boarding time. Seeing as the airport and only road getting to the airport were closed, it seems like they would have been able to make that decision and alert all passengers much sooner. We kept calling in to check on the flight status and they said we would receive texts and emails with any changes, but I never did."
Pros: "Huge snowstorm in Denver caused the airport to shut down. Plane left about 5 hours late. We missed our connection and even though it wasn't Icelandic Air's fault they gave me a taxi, a room and three meals until I caught my connecting flight the next day. Amazing service."
Pros: "Ability to plug into a movie or music and go to sleep"
Cons: "Not being woke up to find out if I want something to eat or drink. Aisle seat and i was being knocked a lot. I had been up over 30 hours and was exhausted."
Cons: "Food had little taste. Movies were not that current and selection was sparse"
Pros: "Crew was great!"
Pros: "The entertainment."
Cons: "The boarding and the leg room."
Pros: "The actual flight itself was fine."
Cons: "The five hour delay of departure was not fine."
Cons: "Lemon pasta mixed with tomato pasta was weird. Little salad was weird. What was it made of?? Not bad, just weird. Choco brownie was nice but richer than Trump's claims about his own wealth. Will get the chicken next time."
Pros: "very nice crew"
Cons: "plane was too small and there was 1.5 hour delay departing"
Pros: "Entertaintment system was good. I was happy with the selection of movies and last releases. No delays in flights which was a plus."
Cons: "Food was terrible. Portions were small, we were given a KitKat for dessert. No side salad or anything. No headphones were given prior to the flight. Long haul flights should always provide these. Most of the flight wasn’t Lufthansa but Air Canada instead. This should be advertised properly as I had no idea."
Pros: "Getting off"
Cons: "Sore all over and a lousy cough"
Pros: "On time"
Pros: "Not much. Crew was good but that is about it."
Cons: "Tight spaces packed in like sardines. FAA seriously needs to look at how these airlines pack us into these seats. Can barely sit in the set, no room to stretch legs, tray table hits my stomach, and I don't even have a big belly. When the guy in front reclines, cannot even get out of my seat. Chaotic boarding process without any order or instructions or announcements, poor food and entertainment."
Pros: "Good boarding.Easy check in."
Cons: "Food! Not appealing. Did not eat more than a few bites."
Pros: "Crew was friendly and helpful. Very efficient with check in process. This leg of flight was operated by TAP."
Cons: "No online check in. Long line to check in. Plane was 30 mins. Late leaving and then had to wait ten minutes to offload. This made us very late for connecting flight which We just made as they closed the door behind us. People that were slower getting through customs did not make the connection."
Pros: "I got to where I needed to go... 3 hours later"
Cons: "My flight was delayed by almost 3 hours. And my luggage got left in Toronto and I went 2 days without it. I tried to contact the company that was delivering it and could not reach them all day. Air Canada never offered to compensate me at all and now I will have to chase them down for compensation."
Pros: "put us up in decent hotels gave food vouchers the crew didn't do anything to make it horrible Large selection of movies/tv on board comfiest seats out of all the major airlines I've flown"
Cons: "The flight kept getting delayed bc of mechanical problems, and then eventually cancelled. They rebooked everyone on new flights, but it took an extra stop in Toronto before getting us to Montreal. Once it was rebooked for the morning, it took off a little late. Plus the pretzels they gave us were stale. This was the first of two flights I took this trip that had mechanical issues, so they obviously need to fix their planes better or get new ones, because two Air Canada flights in one day that have mechanical problems leaves me worried that the planes aren't in optimal condition. It took me over 24 hours to get from Tucson, AZ to Montreal, Canada when normal travel takes less than 8 hours including layovers."
Pros: "Nothing"
Cons: "One of the Worst flights for punctuality 3.5 hours of delays ! Missed all my connections ! Over 24 hours in waiting ! Will try not to use air Canada again!!!"
Pros: "The flight crew were great and very accommodating."
Cons: "A majority of the passengers on flight either barely caught, or missed, their connecting flight due to this flight being so delayed."
Pros: "We flew to Toronto on the rebooked flight and we were treated very badly by the gate agent who simply told us: Go see customer service, you are not on this flight' without even an attempt to explain why we could not get on to the flight to London. I think they do not respect their customers. Very disappointed with Air Canada' service."
Cons: "Nothing about our trip to London on Air Canada was positive. We had requested vegetarian meals for all our flights. They did not provide us any food on the flight because they did not have our names on the list for Vegetarian meals on the rebooked flight. Our experience with Air Canada was everything that is the worst in airline travel and customer service."
Cons: "See above."
Pros: "Food"
Cons: "I had to leave"
Pros: "Good breakfast."
Cons: "Cabin was cool"
Pros: "Nothing! Unpleasant unhelpful crew at gate, no better onboard, absolutely moist cramped seating ever! Disorganized and late- boarding, departing, waited to disembark at arrival, 25 min before first bag off baggage......dreadful no one cares"
Cons: "Thank you for choosing Air Canada- smiles and goodbyes- where's all that Before you leave? They treat you like problem cattle to be dealt with, you're anonymous and valueless until you leave then they look at you and thank you?! Missing sincerity And service!"
Pros: "Onboard attendants were pleasant"
Cons: "No apology for lateness, flight boarded late, took off 40 min late, arrived 35 minutes late but we sat at gate waiting for someone to open it ?!, then another 15 min before bags started to unload Ridiculous but indicative of airlines You are not their valued guest or even their customer, you are a problem that needs to be solved and are consequently met with preloaded annoyance and a readiness to dismiss, placate at the best of times but definitely not please, impress, sympathize or satisfy. There is no evidence that it's even in their lexicon- not a part of their recruitment or selection process or training, ever! They're main focus and only positivity is saved for themselves. There may be a long line of concerned and anxious travelers but their priority is getting coffees for the battle ahead! They break their focused indifference only for each other and enthusiastically leave their post to satisfy each other's needs and attention. This has got to change! Why do we put up with such awful service for which we are the paying customer? Why are we, their customers, not valued? This airline makes record profits, provides less, charges for everything and increasingly delivers bad service, sometimes offensively bad! It doesn't cost more to hire a customer centric pleasant person, or incorporate guest experience into training or at the very least be friendly and smile! What if an airline just did that?! They'd differentiate themselves and develop a positive customer centered culture. Don't we deserve that, at the very least?!"
Pros: "Great seats. Awesome in flight entertainment - got to watch two movies I'd missed in theaters. The food was surprisingly good and the flight attendants were very helpful."
Pros: "Crew was very helpful and nice, plane was new and in a very good condition. Flight was not fully booked so we could move around and take even 4 seats to lay down and fly comfortably."
Cons: "Boarding was over an hour later than it supposed to be. Toronto always has some " surprises" for passengers. Food could be better."
Pros: "Everything was quick and efficient in boarding and replanting, the captains spoke to us to tell us what was going on. Food was good."
Cons: "My tv screen was broken, meal service was pretty late and drinks were not served before, as a result the lights were only off in the flight for a very brief while."
Pros: "The flight was perfect. Stress free. I will definitely get it again."
Pros: "Seats and crew in Premium Enonomy were great"
Cons: "Dinner was nice, but breakfast was lackluster at best - cold slice of banana bread was all we got after 6+ hours of flying! Also, I had a 60 minute layover in Toronto which is considered "legal", but I had to dash through the airport to make the flight and my luggage did not make it at all (and was not delivered to me until 38 hours after I landed in LHR). Would recommend NOT considering an hour ample time for a layover in Toronto going US to UK."
Cons: "Horrible to say the least"
Pros: "Smooth"
Pros: "Free entertainment. Big, spacious plane"
Cons: "Food was disgusting and crew was not very friendly."
Pros: "The seat"
Cons: "1h30 delay once boarded The braeckfast which un fact consisted un only à slice of banana cake."
Pros: "Nothing"
Cons: "Customer service flight rebooking"
Pros: "The price of the flight was excellent and the service totally reliable."
Cons: "Small aircraft for a fairly long overnight flight. Made it difficult to rest as the flight was full."
Cons: "No monitoring of travel route"
Pros: "Everything went smoothly. Everyone was pleasant and respectful."
Pros: "flight was fine pleasant flight attendants was late flight so slept a lot now much to add"
Pros: "They've replaced the ridiculous entertainment system with a much better one."
Cons: "Unwise cost-saving efforts in the Vancouver Maple Leaf Lounge - obscure magazines only, croissants/pastries replaced with a loaf of bread, etc."
Pros: "nothing"
Cons: "i booked a flight through kayak going from denver to milan. i showed up at the airport in denver to fly out yeserday only to find out that i was going to frankfurt germany. i am now in munich germany and never made it to milan. i was one of many people i met on the flight that also booked with air canada thinking they were headed to milan. air canada kept trying to put the blame off to my booking company. i don't know who to be ticked off at. please advise."
Pros: "Staff was great."
Cons: "Seat size made sitting a suffering, as I am quite tall, and was unwilling to pay the extra $100 dollars, which I felt discriminatory (as I have no control over how tall I am)."
Pros: "Better plane than previous"
Cons: "Had to be rerouted to Calgary because I missed my connection"
Pros: "See above"
Cons: "See above"
Pros: "Entertainment choices on this flight/with this plane were endless, and you didn't have to pay extra for them like you do with Condor, for instance. The seats were relatively comfortable, in comparison to the way you are packed into some planes these days. Particularly liked the headrests that were adjustable side to side. It helped in this particular case the flight wasn't completely full, and so I had the seat next to me free."
Pros: "Nothing."
Cons: "The flight attendants on this flight did NOT do their job. If they are there to ensure a safe environment for the people on board, they completely missed the boat. I was in row 45. Two families were on board with their 4 very young children. For the entire 8 hour flight, 3 of these children disrupted the entire section of the plane. They continuously played in the aisles, stood in the seats, kept their seat belts unbuckled, threw objects, and one blasted his iPad at maximum volume. When I asked one flight attendant to ask the family to get the child to lower the volume on his iPad (it was 4am; people were either using their ear buds, or had their screens turned off), they complied with the request for 30 minutes, then resumed at full throttle. I can honestly say, it was one of the worst flights I have ever experienced in 57 years."
Pros: "The flight was more pleasant than I had expected because there was plenty of leg/knee room for me."
Cons: "No complaints."
Pros: "The movie selection...and that is about it really..."
Cons: "The fact that they tried bumping me from my flight without giving a reason. My connector flight (also an Air Canada flight) was delayed so much in Detroit that we got to Toronto with just enough time to board and deal with the bumping issue. Also, my luggage was already on the plane to head to London which noone was worried about if they wouldn't have been able to get me a seat. There was little communication between staff members and nobody seemed bothered by this especially with a late arriving plane that they should have known about and had a way to deal with this issue. The crew on the plan keep bumping into me even though I wasn't in the aisle and never apologized. Totally would give a zero or 1 star (at best if it would let me). Totally will not recommend to anyone and will try to not fly with them again if possible."
Pros: "Wasnt a terrible amout of leg room for coach, and they had Star Wars: The Force Awakens as one of the in flight movies. Food was okay, although they didn't serve it until 1a.m. which was a bit annoying. Good service, very kind workers, and the alcohol was free! Not too many complaints."
Cons: "Didnt serve dinner until 1am. Kind of ridiculous."
Pros: "Lots of entertainment options. The 777 is a huge plane, very comfortable, even in coach."
Pros: "Had 3 seats to myself & was able to stretch out Movie & t.v. Selection Polite and friendly staff"
Cons: "Crying children"
Pros: "Good leg room"
