Pros: "Entertainment"
Cons: "I requested a vegan vegetarian meal and did not get it. I had to do with the regular meal which had a lot of dairy products to which I am allergic to. The space between rows of seats. It was really crammed in Economy and we are a petite thin family!"

Pros: "Entertainment"
Cons: "I requested a vegan vegetarian meal and did not get it. I had to do with the regular meal which had a lot of dairy products to which I am allergic to. The space between rows of seats. It was really crammed in Economy and we are a petite thin family!"
Pros: "The crew was very nice."
Cons: "The seats had such little cushion that it made the flight extremely uncomfortable."
Cons: "We were packed like sardines! My flight made me want to retire from traveling!"
Pros: "Liked the time of the flight."
Cons: "It left late."
Cons: "The plane was SO hot and stuffy. It was an overnight flight, so they passed out blankets—but it was so hot no one used them. The air was stale, to the point of feeling claustrophobic."
Pros: "Crew, food, boarding, service"
Cons: "Very tight seats. Not enough of leg room"
Cons: "It would have better if the flight wasn’t 5 hours late."

Cons: "Seat comfort. Sore behind after 11hrs"
Cons: "A little more leg room would be great"
Pros: "Hospitality was wonderful. The food and drinks were great and the constant entertainment made the 10+ hour flight bearable."
Cons: "The seats are comfortable but there is definitely not enough leg room especially if you are sitting in the middle seat. There should be some type of incentive given if you get stuck sitting between two complete strangers."
Pros: "Food"
Cons: "Everything was great"
Pros: "I do not know how to go about contesting his, but we bought 4 tickets to South Africa on Swiss air and Edelweiss via Zurich. We received a confirmation email for two of the tickets but not for the other two so we assumed the other ones did not go through as we used two different credit cards."
Cons: "We purchased the last two again and when we showed up at the ticket counted they let us know that we bought 6 tickets!!!!!!!! We would like to be reimbursed for the two tickets we did not receive the confirmation emails for. How can we go about it?"
Pros: "The crew was professional and helpful. The flight attendant was especially kind to the children giving them activities and toys to play with. The seats were spacious and comfortable. The food was good."

Cons: "No information on the flight about how to proceed with our missed conncetions nor anyone to meet in Zurich at gate with information."
Cons: "My flight was delayed more than 1 hour at least after overlay of 4 hours. I missed my flight from Vienna to Yerevan and the portion of my trip was detoured to Moscow and from there to Yerevan instead of 3 hours took me 8 hours. As a result of rushing and running in Vienna to catch my flight to Yerevan I feel and injured my hip, I would like a compensation , Please contact me at armine100@cox.net or phone 703-609-8649"
Pros: "The lovely nice stewardess and Crew kindness."
Cons: "I have faced the horrific flight ever in my life last days, I never imagined a completely 4-5 Hours such horror turbulence on a long Night flight. thank God we made, and thank the lovely crew for their super support.."
Pros: "Staff friendly and flight very smooth"
Cons: "The breakfast was very poor. Two different servings of OJ(why?), non fat yoghurt and bread. Coffee came with only one cream. Media screen and audio did not work, and usb charger kept turning off. Barely able to recharge phone over the span of 10 hour flight! My next neighbor had same problem."
Pros: "All very comfortable"
Cons: "It was delayed"
Cons: "They put us in different seats. My 7 year old and 3year old were all sitting separately and we could not switch with anyone. The air hostesses were not as helpful as other airlines."
Pros: "On time and good service!"
Pros: "The food"
Cons: "There was one flight attendant that was rude. The reat were very nice."
Cons: "Nasty landing, last 5 min plane dropped 4to 5 times for whatever reason. Felt like it was a sesna"
Pros: "Friendly team, great food and snacks and tons of movies to choose from."
Pros: "Flight was on time. Food was good for airline food."
Cons: "Swiss air seems to have lost its service edge. The flight attendants just stood around and watched while I struggled with my cane and my bag. They only seemed to snap into action to tell people what to do or not do. I flew the same route two years ago and staff was really kind. Maybe the working conditions have changed; they seemed harried and annoyed (in coach, at least). And I don't think they had to stand in line for an _hour_ to check in (thanks, LAX)."
Pros: "Food great!"
Cons: "Limited space , very narrow and not very clean. I seated next to a dog, pet. The whole trip the dog was sitting on the floor next to me:(, although it was a very quiet and good dog. Crew not very friendly . They were tired I believe ."
Pros: "Flight attendants where very nice and attentive. Good choice of movies and shows for adults and kids. I usually don't eat airplane food but it looked fresh and my kids enjoyed the breakfast very much with fresh baked bread and croissant. My flight was delayed by one hour but it was a problem caused by the airport not the airline. I still made my connection and I received my suitcaises right away."
Cons: "Boarding was a little chaotic"
Pros: "The crew made the right call after the Swiss computers shutted down"
Cons: "Boarding problem. But I have to congratulate the crew for their efforts to overcome the problem in the best possible way"
Cons: "Very narrow seats. Seat in front reclines in your face. Terrible experience for 100% full long haul flight from LAX to ZRH"
Pros: "Traveling with 3 kids, Swiss kept our seats the same, had our special meals sorted, crew was kind and courteous. Entertainment for everyone."
Cons: "Overnight flight lights too bright, economy seats very narrow (and that's all we ever fly), it was extremely difficult to sleep."
Cons: "I paid extra for a seat with more room but found that the seat did not offer any more room than the average coach class seat in any other airline. That was unexpectedly disappointing."
Pros: "The larding was terrible. I came in a wheelchair but am able to walk short distances. I spoke to man at the gate about boarding early and he said he would come and get me. But he did not and I had to push and shove with everyone else as their is no plan. Awful! Service was good. Lots of water and juice brought round in the night of"
Pros: "zurich a great airport."
Cons: "cheese roll"
Pros: "So far so good."
Pros: "Flight crew and gate agents were amazing"

Pros: "That is wasn't crowded"
Cons: "That I had a 5 hour delay and I was t informed about it earlier"
Pros: "The entertainment consoles are great, plane is modern and clean, staff on board are very considerate and helpful. Flight left and landed on time and our luggage arrived intact. Everything that we paid for we got."
Cons: "The space between the seats is very small, and the seats recline very far, I found myself a bit too tall to fit in them comfortably, as even reclined my neighbors seat was nearly pressed against my nose. My much shorter girlfriend did not have this problem, and slept through the whole flight. SWISS only has one or two check in agents at LAX, and the wait was about 3hr to process the 300-odd passengers on our 777. I know they're only running a flight or two a day from LA, but I am sure there's a speedier and more efficient way to check us all in."
Pros: "Crew was really nice, comfortable seat, great experience"
Cons: "I liked everything"
Pros: "Great entertainment center. Complimentary alcohol and snacks. All this masks the torture of sitting in a way -too-small seat for 11 hours plus."
Pros: "I loved the food, the crew, and the entertainment."
Cons: "Nothing"
Pros: "entertainment system was good. Pilot was nice crew was pretty nice ."
Cons: "No leg room uncomfortable seats food has gone way down hill since 2 years ago. None of the good chocolates anymore. check in people at the gates were cold fish."
Pros: "Great food and sevice"
Cons: "Hard to sleep on the plane. Way too expensive to take a guitar as either checked luggage or carry on."
Cons: "I have used the same carryon on several trips & only Swiss would not let me carry it inside telling me it was a bit high. Disappointed & surprised since never before I was told I had to check-in my carryon containing some essential items."
Cons: "I was asked to move from my reserved seat for another flyer"
Pros: "The straff is very nice. this made the flight a positive for me"
Cons: "i work with tech stuff and i couldnt find the switch for english on the entertainment system, or how to turn it off so the glow would bother me."
Cons: "I cancelled this flight online, then I called to let them know I was getting emails, but that I had cancelled. For two days I received emails about delayed flights and now this."
Pros: "The crew were very attentive, they tried hard to help me with comfort, drinks etc. I didnt have food as it was so good in the Virgin Clubhouse!"
Cons: "The bed! When you flip it flat its rock hard, and the matress they provide is useless! Need foam matress to really make it more comfotable. If the seat reclined another few inches i wouldnt bother flipping it."
Pros: "A smoothtrip run by great staff."
Cons: "Thé food was rather stodgy overall."
Cons: "Seats were tight."
Pros: "Staff. Very couteous.polite. friendly."

Cons: "No flight"
Pros: "Top glass airline"
Cons: "I lake food and good service crew"
Pros: "Although we were badly delayed the cabin service was excellent in every way. Good meal , cheerful staff and well turned out."
Cons: "I did not like the fact that my seat was between 2 small children that belonged to a family sitting behind me .It was ridiculous to put a stranger on a 10 hour flight with a 3yrar old on one side and a 5 year old on the other"
Pros: "Staff on this flight were excellent"
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: "Overall comfortable journey"
Cons: "No option to book food option 24 hours before as could check in could not been done earlier than 24 hours before flight. I logged exactly 24 hrs before filled in details which took a few minutes by that time said too late to book special meal."
Cons: "It was terribly late. No one had a clue on when flight would depart."
Pros: "Nice airline, great crew and service."
Cons: "Leg room and space was great but the seats could use some more cushion."
Pros: "The entertainment selection was good, though I didn't need to see the blurb about having vloggers available before every movie. One of the very few airlines to use boarding by rows, which speeds up the boarding process."
Cons: "The legroom is very cramped, pretty difficult to eat your meal with the seat in front reclined. The crew were not very attentive: they completely missed me while I was waving the rubbish on their collection rounds. In the end I had to dump it myself in the toilet bins. The PA system is too loud compared to the rest of the entertainment, had to remove the headphones for each one of them."
Pros: "good plane and timing"
Cons: "meal was not served according to the request and no sound support from the staff"
Pros: "The crew was the best part of my experience, super nice and accomodating"
Cons: "the wifi had subpar performance"

Cons: "given milk yoghurt with VGML breakfast"
Pros: "Seat is very comfortable"
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: "From the check in to the service on board was very good. Staff were polite and respectful."
Cons: "The food was small. There did not serve bread with the meal"
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: "I liked that the boarding went really fast and the staff at the JFK airport was super nice and helpful."
Cons: "I didn't like how rude the airplane crew was and how useless and unhappy they were. The sits were very uncomfortable and the food didn't have any taste."

Pros: "The flight was late but the pilots made up most of the time"
Cons: "Uncomfortable seats"

Pros: "Safe flight, good crew"
Cons: "Food quality was poor."
Pros: "Just the food and boarding was fine."
Cons: "Everything else was bad. I think crew were a little rude!"
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: "Food"
Cons: "Seat reclining happens even during meal time and landing! I had to ask crew to get passenger in front to put seat back upright during meal time!!! Crew should've noticed themselves and ask the passenger without my prompting!! So annoyed!! I complained to VA too"
Pros: "The service, the service. My wife got a cheese and fruit platter after dinner. Crew went out of their way to make us feel special and welcomed. Excellent service."
Cons: "Nothing to complain about."
Pros: "The food was surprisingly ok and the seats in PE were comfortable, plus there were two USB ports, perfect!"
Cons: "Being woken up to be asked if I wanted to eat, twice! If I wanted to eat, I wouldn't have a sleeping mask on my face, or be asleep! Plus, upper class and premium economy didn't board first."
Pros: "Genuinely pleasant cabin crew, good service, good food."
Cons: "Virgin Upper Class seats are cramped, with very limited stowage space. Turning the seat into a lay flat bed (and returning it seat at the end of the flight) takes some effort--not the simplest of processes. I'm not tall, but my feet protruded into the aisle so I was being disturbed whilst sleeping. Seat is also quite narrow--feels quite claustrophobic when sleeping."
Pros: "Still a more pleasant experience than BA but others have overtaken. Crew make a difference though."
Cons: "Limo service wasn't great in China - asked for address of hotel - a major international chain and confusion on booking details"
Pros: "The service went a mile farther. It is my favourite airlines!"
Pros: "New Dreamliner aircraft was very comfortable with loads of leg room for a tall person like myself at 1.76m"
Cons: "My seat was directly under the aircon and it was blowing very cold all night which made it quite uncomfortable. Fortunately I had an extra blanket which I could wrap over my head."
Pros: "The boarding and the overall flight experience was quite good."
Cons: "There were movie options such as Sully and Deepwater Horizon, which I think are unsuitable for flights. Overall, the movie options could have had more variety."
Pros: "Smiling and helpful staff Great FREE food and drinks good movies Free goodie bag of travel goods, blanket, pillow etc Free candy for landing descent"
Cons: "Leg room is a little tight"
Pros: "The crew,food and entertainment the food has improved, the ground and flight staffs was very pleasant and helpful"
Cons: "We were flying to Miami, then into a cruise,weighs restrictions,we were find a100 dollars for a couple more kg, we were on holiday for nearly three weeks"
Cons: "Crew"
Pros: "The crew left my breakfast in the sear next to me because I was asleep (unfortunately i didn't notice till I started to disembark...)"
Cons: "I couldn't get comfortable enough to sleep very well, even though I was in a window seat (which I can normally lean on)."
Pros: "Everything except the plane itself"
Cons: "Plane cramped"
Cons: "3 1/2 hr delay"
Pros: "Dinner was great"
Pros: "Crew and service was amazing"
Cons: "Paid $28 for internet and it didn’t work"
Pros: "Cabin crew and entire experience was phenomenal. Cannot recommend Delta more!"
Cons: "Nothing"
Pros: "Had seat open next to me"
Cons: "Delays on afternoon flights East create all sorts of problems; fewer options the later the arrival"
Pros: "Crew was amazing"
Cons: "Food could have been better, seat was uncomfortable."
Pros: "Crew, food, flight."
Cons: "Could always use a wider seat. I just hate having my hips touching a stranger for the whole trip."
Cons: "Wonderful"
Cons: "Seats hardly recline. Very difficult to sleep in this red eye flight."
Pros: "Some of the crew members talked loudly in the galley all night long. Mostly gossiping and complaining. We had the last seats next to the galley, so it was frustrating to not have quiet and be able to sleep. This was a flight run by Delta for Air France."
Cons: "The food was horrible."
Cons: "Plane very late. Boarding was chaos"
Pros: "Flight was overbooked!!!! How dare you overbook your planes? If you do that, get new plane!!! People loosing time and money.. 9 people couldn’t get seat on the play they paid for... tomorrows flight is same sting... this is last time fling delta... and we are silver medallions... who fly a lot!!!"
Cons: "Flight was overbooked!!!! How dare you overbook your planes? If you do that, get new plane!!! People loosing time and money.. 9 people couldn’t get seat on the play they paid for... tomorrows flight is same sting... this is last time fling delta... and we are silver medallions... who fly a lot!!!"
Pros: "Lisa @ the Boston Delta check-in counter is AMAZING! She's super helpful and essentially saved our vacation! Her coworkers say she's the best and I couldn't agree more! Delta is very lucky to have someone like Lisa on their team!"
Cons: "Nothing to complain about! If I really head to be picky maybe the in-flight meals were smaller than I expected. But again, nothing that bothered me"
Pros: "Pilot and his ability to maneuver the turbulence. Also variety of snacks."
Cons: "Felt hot in the plane."
Pros: "The movies offered were decent"
Cons: "I paid extra for a window seat I sit down after they squeezed us all in like sardines and come to my surprise there is no window in my aisles it had been covered up in plastic . First making my area narrow than all the other seats and between the plane leaving late and the terrible process of loading people on the plane . Delta airlines was all about the up sale from charging for every bag to charging for internet ,food so on and so forth. Also one bathroom in the middle of the plane ? REALLY ? Out of tissue , paper towels , and tissue one hour into the flight . What in the Hell is going on with this airline ? Won’t fly with them again ."
Pros: "very fast boarding , attentive , and easy to figure out"
Cons: "seats cushions"
Pros: "No problems occured"
Cons: "Takes so long to board"
Cons: "Noise in cabin unable to sleep"
Pros: "Great service. Smooth flight. Funny flight attendants. No issues boarding or deplaning."
Cons: "Food wasn’t great. What’s new?"
Pros: "Got to London on-time (early, actually) and safely. The in flight meal was okay. The leg room in comfort plus was great, the mobile app was awesome, and the staff (check-in, gate, cabin and flight deck) were professional and friendly all around."
Cons: "The leg room was great, but as a broad-shouldered guy, the width of the seat was miserable. Unfortunately, the Delta 767 doesn't offer any upgrade for a wider seat beyond Delta One, and my employer won't spring for that. Too bad there isn't a premium economy option. Also, the entertainment unit in the seat next to mine malfunctioned, which you wouldn't think would impact me that much except that because it was "seeing" touches randomly throughout the flight, the screen would turn on, off, brighter, dimmer, play random stuff, and just generally be as annoying as possible to everyone nearby throughout an overnight flight."
Pros: "The plane left on time if not a bit early."
Cons: "With the exception of 1 really nice flight attendant all the others were extremely moody and not helpful. I didn’t see one of them smile through the whole flight like they were just going through the motions. I’ve worked in jobs where you have to deal with the general public but you have a job to do and must smile and do your best to be helpful. I felt intimidated to even ask for anything like I was wasting their time. I love flying Delta and this was my worst experience yet."
Pros: "Seems like people that work for Delta are too old and too comfortable. Don’t want to work nor do they appreciate customers. Gate agent in SLC complained she was the only one there and could not help. Tried to send me tohelp desk which would have made me miss my flight. Flight attendant couldn’t move my back pack in bin did not tell me she had a bad shoulder. She should not be working then if she can’t lift a small backpack. Omg"
Pros: "The staff"
Cons: "Nothing"
Pros: "Great service throughout. Friendly attendants and easy boarding/deboarding processes. Would fly international with them again in a heart beat."
Pros: "Quick and easy boarding. Quick flight"
Cons: "Audio entertainment quite limited"
Pros: "Staff are nice, and helpful"
Cons: "Take far too long, efficiency is extremely poor, missed flight due to luggages being lost, requested vegetarian meal, when booking, confirmed at gate but didn't have me on the list for special meal. ECONOMY class has nooo room for a long flight...and no entertainment only 3 choices for western."
Pros: "Food good, wine OK"
Cons: "Discomfort bad"
Pros: "Space looked a bit cramped in business class but I was pleasantly surprised at the length of the flat bed and the additional foot well space once I'd reclined the seat."
Cons: "Need to fix the flickering lights in the JFK club lounge, the opposite of relaxing!"
Cons: "Price to get a little more space"
Pros: "Crew was very helpful."
Cons: "Food was terrible and check in can be more organized."
Pros: "I booked via Kayak using Virgin Atlantic shared out to Delta. Check was confusing as both airlines used different flight numbers. When I went to check in with Virgin Atlantic they told me to go to Delta. When I went to Delta they told me to go back to Virgin Atlantic. I wound up checking in with Virgin Atlantic. Everyone was very polite but check in was confusing. Everything else was wonderful. Cutomer service was great from beginning to end."
Cons: "Check in."
Pros: "More seat room than expected for economy tickets. Good service, on time, polite staff"
Cons: "Duty free purchases not waiting for us at boarding like usual. Audio selection on entertainment was v poor"
Pros: "Delta has a pretty good entertainment system. Lots of movies to watch and the system works well."
Cons: "Seats are very tight and uncomfortable. The food was horrible. Tasted like a $1 frozen meal that was microwaved til mushy. It was chicken but I couldn't tell you more. And flight attendant helpfully described it as 'chicken'. Breakfast was a cold roll, a piece of cheese and some awful yogurt. This was the most unbearable 8.5 hours of my life."
Pros: "Crew were good, flight on time, free drinks"
Cons: "Nothing"
Pros: "Thomas our steward was excellent."
Pros: "Had a great experience on my flight. All on time, and connections were great."
Pros: "The flight was smooth and the food selection was surprising delicious. The crew was very attentive."
Cons: "The leg room was much less than the last time I flew Virgin (booked via Delta) and made for an uncomfortable trip. Could not sleep as a result. If you're tall like me you'll need to book a higher seating category."
Pros: "Everything that British Airways tried to do to help us when Delta didn't want to take ownership for their screwups!"
Cons: "Not only did we miss our Delta connection but when Delta rebooked us on a British Airways flight they refused to help when British Airways could not access our tickets. they kept saying since it was Virigin Atlantic who we originally booked through that VA woulkd have to fix it, even thought Delta was the actual carrier and the ones that did the rebooking onto the British Airways flight"
Pros: "I had 45 minutes to transfer planes in Atlanta and made it in plenty of time even though it was far. plenty of information given regarding incoming flight and departure. Boarding was also easy."
Cons: "The engine noise in the plane was so loud I couldn't watch a movie. My gluten free meal was awful and tasteless. I would have preferred yogurt and fruit instead of the chicken and vegetables with a rice cake."
Pros: "My Delta flight was a code share with Virgin Atlantic. A pleasant flight overall with my first impression being an airline with current popular music playing in the background and flight attendants cheerful. Since I was traveling alone, I opted to not purchase my seat prior to my flight date, instead I chose my aisle seat within 24 hours for free. I checked in my one bag and found out I had pre-checked so my security check went so smooth at the new terminal 2 at LAX. Looking forward to my flight back on June 15."
Cons: "Had a toddler behind me crying and screaming the last 40 minutes of landing into Heathrow because she couldn't sit on her mother's lap and made it quite unbareable for all of us in the vicinity. Wondering if there was an alternative way to handle the situation."
Pros: "Everything was just right"
Pros: "On my ticket it clearly indicate that I am entitled to 2 check in baggage. Delta completely refused to honor this. They said am only entitled 1 piece, and therefore I have to pay for the other luggage. I was forced to borough money from someone at the airport just so that I could board the flight."
Cons: "I am asking that my money be refunded. And next time delta should honor and respect agreements. And be more professional"
Pros: "The amount of movies to watch"
Cons: "Seating not enough room, couldn't use the overhead lights for 7 1/2 hour flight. Ridiculous."
Cons: "The food was supposed to be hot chicken was served cold"
Pros: "They offered water and snacks It was quick"
Pros: "Online check in was very good. Liked the ability​ to select free seats ahead of 24hr window. Liked being air side for the whole trip Detroit airport Terminal A was good. Free WiFi 50mb + awesome. Crew were friendly and efficient Will do this trip again."
Cons: "Seat always seem uncomfortable after 3hrs anywhere! And more leg room would always help. Food was OK liked the choice of 3 meals difficult to do quality food for 200+ but keep trying to improve"
Pros: "The seats were the widest with the most cushion and padding I've ever had on any flight, I think all their seats were like that. The plane we were on had more leg room than your average flight. Also the backs of the chair were very tall, leaving even mpre head room perfect for tall people . I fly a lot and sometimes my knees hit the seat in front of me or when they recline it shoves the tray to close to you. Not on this flight there was enough room for me to lay back in the seat had the adjustable headrest that went up and down and also curved in to hold your head from falling on your neighbor next to you. Love the fact they had the USB plug-in in front of you. And the crew constantly kept coming through to empty trash and offer beverages. The plane was clean bathrooms in front and back of the airplane. Over all quiet engine and we were above the wings. Temperature good."
Cons: "The crew member that was checking in people at the gate would talk so fast we could barely understand what he was saying on the overhead announcement. I was traveling with someone who was hearing impaired so we were unaware of that they were getting ready to board. The electronic TV monitor wasn't updating to say boarding to notify people that would be helpful for the hearing impaired. Or--if a crew member is muffled on the announcement or talks too fast you can't understand or know what's going on. The most frustrating thing for me and my daughter we were both expecting to use Delta online entertainment. There are no monitor screens in the seats in front of us on this plane. So we were able to use our phones, but it would not download and once It finally downloaded we couldn't upload any of the movies. Connection speed way too slow. The warning said there were too many people on it at that time. Also I like it when they offer free headphones for people that don't have them. An example that would benefit people that don't want to listen to loud people on the plane or babies that are crying."
Pros: "Over all was okay, but when we all boarded the plane, they last minute said the pilot would be late, and delayed our flight for almost 2 hours. We were almost late to our next flight in Minneapolis to Raleigh which was also pretty upsetting. But, the service was decent, we didn't order any food besides the free complimentary drink & snack and the entertainment was very good. There was a wide range of films, shows, and podcasts to watch."
Cons: "Management was very bad- Delta screwed up really bad"
Cons: "It was Delta not Virgin"
Pros: "The in-flight service was extremely good."
Cons: "The seat was slightly too short for me. If Delta provided a soft mattress cover, slimiler to that of Virgin Atlantic, then the flat bed would be far more comfortable."
Pros: "Yes"
Cons: "Yes"
Pros: "The seat wasn’t working properly"
Pros: "Free alcohol"
Cons: "They overbooked the flight after I called to verify this didn't happen. The night crew in LAX (11/22) were rude, unhelpful and bad people. If I were a manager I would have fired everyone. I will never use Avianca again"
Pros: "Overall trip was ok"
Cons: "Lady guiding people to register luggage was rude"
Pros: "decent comfort on board"
Cons: "both flights delayed, some rude crew, and Avianca lost my luggage when I got to Medellin"
Pros: "Good schedule"
Pros: "Crew was great and friendly. The red-eye flight was half empty so I had a row to myself to sleep."
Cons: "I called two weeks before the flight to confirm my specific sport gear baggage fees (surfboard bag). They confirmed it would be $100 each way on Avianca. When I arrived, surprise, they said it’s busy season so now it’s $150 each way. Felt like they scam people when you have no choice at checkin."
Pros: "Great crew, organized, smooth flight, the team was awesome with my kids on our red eye, which made for such a better trip."
Cons: "No breakfast in the AM. I didn't mind because I wanted the time to sleep anyway, but we got there early"
Cons: "The food"
Cons: "The issue I had was with a flight delay, our flight was delayed by 2 hours, we had no time to make connecting flight in BOG, I cant physically run, missed my flight, gate was too far away, voucher was invalid, BOG took my water, only alcohol in BOG, little to no water, so avoid or get dehydrated!"
Pros: "Comfortable aircraft!"
Cons: "Food can be better, very long lines at the airport."
Pros: "The crew was accommodating"
Cons: "The seats were uncomfortable and they changed my flight 3 times"
Pros: "Pretty much everything was great!"
Cons: "We got there to check our bags about 90 min before check in bc we were trying to avoid the chaos of rush hour time at LAX but avanica wouldn’t take our bags that early so we had to drag them around and wait till there’s were plenty of other people in line. This all could of been avoided and easier."
Pros: "service, great plane, always on time. With Avianca you cannot go wrong. if you find a Delay is usually not because of them"
Pros: "service, great plane, always on time. With Avianca you cannot go wrong. if you find a Delay is usually not because of them"
Cons: "Seats are to small and food was overall not to par"
Pros: "On time"
Cons: "Service was a little off"
Pros: "Nothing"
Cons: "Having to leave airport after waiting hours for a repair"
Pros: "Crew were super friendly, helpful & spoke both Spanish & English. In flight entertainment touch screens didn’t work properly. Therefore I couldn’t use behind & the customer behind me kept pushing my chair, in an attempt to get her touch screen to work"
Cons: "Touch screen entertainment"
Pros: "Good entertainment and food."
Cons: "The flight was quite delayed, and also had to wait a while once landed. Not much leg space."
Cons: "Very poor traffic prevented us to get to the airport very early but we had checked in prior with boarding passes and assigned seats 45 minutes before the flight was to take off. The people at the counter refused to let us board saying we had to be there one hour before the flight because it would take them half an hour to check in the luggage. In the end, we had to pay an extra $600 to rebook another flight to leave a week later."
Cons: "A rating of one start is too much for this airline. Avianca caused me to miss my flight in LAX, refused to help me reach my ultimate destination for which I paid them hundreds of dollars to do, nor did they offer to credit my losses for which they were responsible. Customer Service was as useless as the individuals in person that I dealt with. I never made it to my destination because I was forced to return home to San Francisco, unable to see my wife-to-be in Brasil. I will never fly with this airline again."
Pros: "Checkin staff very helpful and quick boarding. Infligjt staff polite and professional"
Cons: "No much leg roon."
Cons: "Because the lady take aur bagagge the bascula is doesnt work she was very rud but we go to the other lady the bagagge was correct because we know is okey because we check at home in the airport too so agter that yhey know the bascula is bas and she don say sorry end enyrhing for the bad time she was lake I dont care so that happen"
Pros: "Newer plane"
Cons: "It took forever to turn off the head light"
Pros: "The flight was on time and comfortable"
Cons: "Waiting for immigration purposes, due to crowed area"
Pros: "The tv"
Cons: "They changed our flight at the last minute and didn’t ask - just did it. Screwed our schedules up"
Pros: "Nothing"
Cons: "Seats were very uncomfortable. They cancelled my original flight and gave me 2 stops. When I tried to call customer service, I waited in the phone for 5 hrs and no one ever picked up. I gave up my seat as they asked and they told me I would get an aisle seat, instead I got a middle seat and they said they can’t change it back."
Pros: "Everything went fine until I got to Bogota and had to pick up my suitcases... they were to end in Cali"
Cons: "Having to change my flights from the bigining... the reason why I buy my tickets a months in advance is so I can have what I want and ask for... so changing from a direct flight from LAC to CLO and the. Having to have 3 stops want fun at all!!"
Cons: "Avianca Airlines down loaded my two check in bags in Bobota, Columbia and left them behind. Still waiting for the bags to arrive in London. Very inconvenient."
Pros: "The flight schedule"
Cons: "None"
Cons: "Delayed 3 hours lost conection to Istanbul and change the business for economy in the last fly"
Pros: "Nothing"
Cons: "They cancelled the flight and couldn't get us out for 24 hours and wouldn't accommodate us on other airlines"
Pros: "Aside from the issues below, it was a good flight."
Cons: "I was seated by an emergency exit, so i couldn't tilt my seat back. Also, everyone who walked by hit my left arm back and forth. It was very annoying. The cabin felt a bit claustrophobic."
Pros: "Very comfy. Very easy flight"
Cons: "Everything went well. More leg room would be nice"
Pros: "Boarding, plane, entertainment were very good."
Cons: "During a six hour international flight, we only saw the crew once, when they served the not very good food. Actually, bad. After that, nowhere to find something to drink or a snack. It just seemed impossible to get someone, since the back of the plane was full of people all flight."
Pros: "Staff was friendly"
Cons: "Seats were clunky, I couldn't recline my seat during a 10 hours night flight."
Pros: "The seat (space, comfort, cleanliness) was good"
Cons: "The crew (flight attendants) need to be trained much better if Avianca hopes to be a international airline. The attendants spend too much time sitting in the back of the plane and not enough checking for excess trash, customer comfort and general visibility. During the in-flight meal I found an object that looked like a piece of a plastic tie. I gave it to the flight attendant but she appeared unconcerned and indifferent to the situation, making no apology what so ever."
Cons: "It was my sister's first flight ever. She was late to the airport (LA traffic) and then treated absolutely horribly by the agents at the desk. She ended up missing the entire trip on account of these heartless agents who refused to honor the "flat tire rule.""
Pros: "Crew was nice and individual tv screens were great! Free wine."
Cons: "God tasted like cardboard."
Pros: "Crew So kind"
Cons: "Food was not enough"
Pros: "The crew was professional and all the amenities made up for the terrible food."
Cons: "I ordered the steak and it was so dry I could not cut into it. Salad was uninspiring. I upgraded to business class and expected more."
Pros: "Crew, food, airplane, cabin"
Cons: "Chair is not comfortable to sleep"
Cons: "El desayuno estaba un poco frio"
Pros: "Nothing"
Cons: "The check in line at the airport was way too slow. When we got to the clerk she told us that we better run to the boarding area. They full the plane with passengers going to South America and the luggage for people going to san salvador was left at LAX. That was on Monday today is Thursday and the luggage still in LA. I don't think will be using this airline again."
Pros: "Your flight was the most comfortable coach flight I have ever taken. No other airline I've taken for as long as I can remember has provided the leg room and comfort that your airline provides for coach"
Pros: "The price was awesome"
Cons: "Food was mediocre"
Pros: "Avianca is top rate, great food, great people and excelent service. Free in flight movies and whisky, what more could you ask for?"
Pros: "Very professional service, nice people, newer airplane, plenty of entertainment options, got my luggage where it needed to go despite 2 connections."
Cons: "I was put in a seat before the exit row, meaning my chair did not recline for a 5 hour flight. In addition, the seat in front of me was at least 3-5 inches closer than any other seat on the plane. I understand there are these seats on the plane, I just wish I would have known prior or been given the option to change seats."
Pros: "Food, service and comfort"

I missed the flight!!!! , they left me !

Pros: "Place was clean; crew was nice and attentive"
Cons: "Seats are small and uncomfortable for long haul flights"
Cons: "Everything was super. Really"
Pros: "The confort and quality of Lufthansa is excellent!"
Cons: "Better food"
Pros: "The bus was one of the most comfortable international flights I have ever been on."
Cons: "Somehow, our luggage never made it to Rome, despite a nearly four hour layover in Munich. Disappointing."
Pros: "Not much compare to other airlines"
Cons: "Food!"
Pros: "The seat is not comfortable. although the plane was an A380, but the configuration is not as comfortable ASIANA."
Cons: "The boarding process is so poorly organized : very very long lines, just a couple of gates for security. The worst I have ever seen is at the Frankfurt airport. It is so bad that I swear I would never fly Lufthansa again. Talking about German efficiency ... nil ."
Pros: "Entertainment"
Cons: "Female flight attendant was rude and unprofessional."
Pros: "Smooth flight, good service, seats above average"
Cons: "Food quality has gone down"
Pros: "Flight crew and airport crew very helpful"
Cons: "4 hrs delayed which delayed my whole trip over 6 hrs"
Pros: "Service. Crew genuinely cared about passengers.Well done."
Cons: "N/A"
Pros: "Arrived/departed on time and didn’t lose luggage"
Cons: "Paid extra for reserved seat that was free a few years ago—a very uncomfortably cramped seat."
Pros: "Great movie choices . Flight on time, comfortable. No turbulence, smooth."
Cons: "I did not like the food … I’m allergic to dairy so I can’t have cheese or cream in pasta or milk in polenta with beef stew. So there wasn’t anything for me to eat. Plus the crew should tell you what kind of pasta you’re getting! I got the pasta but I didn’t know it was filled with cheese and cream but by the time they came back to me I told them that I can’t have this they didn’t have anymore left of anything so I didn’t have anything to eat. And the breakfast the next day was awful. And by the way I saw that the crew had a really good meal. I should be able to pick up meal ahead of time… When you’re booking. It was a long day with no hot meal."
Pros: "The crew onboard the flight was very friendly and accommodating! They did their best with what they had. I also like that there were diabetic and vegetarian meals offered, although the diabetic meals should ideally focus on lower carbohydrate totals. Fruits and breads can pack just as much sugar as sweets."
Cons: "Starting with the boarding area at LAX, there was some really high pitched siren that kept going off over and over which no one seemed to care to investigate or do anything about. It was very irritating, and seemed to put lots of passengers in a bad mood before the plane even started boarding. Then when they announced boarding was beginning, everyone got up and created massed around creating four chaotic lines. It was a mess. We left 45 min late, which caused us to run to make our connecting flight because the person at the gate never told us it was also going to be leaving late. The plane itself was extremely uncomfortable as well. I'm 5'8" tall and that's mostly torso. I fit easily in the back seat of my buddy's mini Cooper, and I could barely fit in the space without my legs hitting the seat in front of me. That was before the guy in front of me put his seat back and made it so I could barely reach under my seat. Then there was the control panel for my personal video monitor. The panel was located on the armrest in just the right spot where Everytime I put my hand down I accidentally pressed a button to call the flight attendant, or turn the video screen on off, which was really obnoxious when I was trying to sleep and kept accidentally turning on the bright screen which woke me up. The video monitors we're also touch compatible, but the screen was horrible about registering finger presses which led to the lady in the seat behind me smashing the screen as hard as she could repeatedly with her finger, which vibrated all the was through my headrest so I could feel it as if she were trying to get my attention. There was also no air flow above the seats... You simply had to rely on the flight attendant to set a temperature that the whole cabin enjoyed, or you had to suffer silently. Finally, the reading lights on the plane we're so high up that turning one on lit up all the seats around you as well, which meant you had to choose to either sit in the dark and not read, or turn on your light and read quietly while the people around you cursed your name while attempting to get some rest."
Pros: "Everything"
Cons: "It was great experience with them"
Pros: "everything about this airline always amazing. Great service well thought out, friendly staff, everything happened as it was supposed to and I felt very cared for."

Cons: "In economy class, seats are packed tight"
Pros: "The Crew was very attentive und friendly! The flight was in time"
Cons: "Nothing"
Pros: "Service was efficient and non invasive."
Cons: "We had to land in Bari, due to weather, and the airline initially wanted to take us back to Munich for the night and return to Naples in the morning. They ultimately opted to drive us down to Naples but didn’t arrive at that decision until we’d been on the ground for quite a while."
Pros: "The boarding process was orderly, the seats comfortable, plenty of luggage space, excellent food -- one of the best economy class flights I've taken."
Pros: "Not a thing"
Cons: "Bad seats in premium economy. Rude staff."
Pros: "The food,Entertainment,was good boarding was awfull changed the terminal 2 times 55-60 min late, one of the crew member was rude."
Cons: "I assigned seats for me and my daughter but they separated us in both legs. That's not good"
Pros: "The food and service"
Cons: "I don't have my luggage yet!"
Pros: "We landed safely and weren't too delayed."
Cons: "Food has not been good."
Cons: "The kosher food was terrible!!!!"
Pros: "This was one of the most aggravating flights. I had a connection. Both flights were delayed and i had to run through the enormous frankfurt with my carry on cat. When i got to the next flight it was delayed 30mins and there were little updates. When i arrived in oslo i was late and so missed my connecting train. I had to wait 6 hours in the station for the next train. An exhausting and frustrating experience. There was one helpful steward on the lax frankfurt flight but the rest of the staff was not helpful."
Cons: "Flight delay for over an hour with United"
Pros: "Selection of movies in the entertainment section. Food"
Pros: "Online check in is efficient, staff both at the airport and on board are friendly and helpful. Seats (economy) are OK. Onboard entertainment is good (good choice of films, TV shows and games)"
Cons: "Food - as usual airline food is mostly inedible and unappealing. I usually eat at the airport before the flight and skip the meal onboard."
Pros: "Kostenlose Wein, Weinbrand usw. Und Sendungen von Bundeliga. The flight attendants were also very friendly."
Cons: "Nothing"
Cons: "Very annoying person next to me. I know that wasn't team's fault but she made my flight terrible."
Pros: "Lunch was really good..yet,bread needs to be warm it adds desired comfort during the long flight."
Cons: "Breakfast need to include something else ,not just eggs. There should be an alternative for those who are allergic to eggs ,like me. Couple of hot wheat pancakes with Apple sause would do."
Pros: "Entertainment, comfort"
Cons: "Food was not good. Too salty."
Pros: "Despite the tight connection we made the flight to barcelona, a special work around bus was used - very effective."
Cons: "Flight was delayed in take off due to weather and arrived late making connection to barcelona tight. Audio visual system on flight was poorly responsive"
Pros: "The flight itself was great... A bit of turbulence, but otherwise quite comfortable. Crew and captain were excellent."
Cons: "The plane arrived 2 hours late, causing me to miss a train from Marseille to Nîmes, and costing me money for an extra night's hotel that I hadn't planned (Marseille), plus wasting money for the night at the hotel that I HAD planned (Nîmes), plus the cost of having to purchase an additional train ticket for the following morning. The $7 voucher at the airport was nice, but honestly doesn't come close to making up for the cost and inconvenience."
Pros: "The flight attendants were very friendly and welcoming and eager to help. The flight was comfortable and had nice accommodations."
Cons: "The breakfast meal was a little different."
Cons: "We booked our group of four with Lufthansa, paying $300 more than equivalent flights on competing airlines, specifically because our 20 month old daughter fits within Lufthansa's age, height, and weight limits for using the bassinet. We have reserved our tickets and the bassinet over two months in advance, paying $35 extra per seat for these reservations, and even got an email that specifically stated "bassinet confirmed". On the flight, when it came time to install the bassinets, the flight attendant came to us, took a look at our daughter, and said that she will not fit in the bassinet, that she is too tall, and too heavy, and suggested that we should have checked the limits for the bassinet before coming on the flight. When we inquired as to the actual limits, she could not provide any numbers, only said that she could see that our daughter is too big for it. When the family next to us got their bassinet, it became very obvious that our daughter would fit in the bassinet, and we pointed out that she was well below the height and weight limits published on the Lufthansa website. Only then did the flight attendant admit that there were other babies on the flight, and they only had four bassinets on the plane, despite having 11 slots where bassinets could be installed. Our reservation months in advance did not matter - we did not get the bassinet. As compensation, we were offered some Lufthansa miles, or 50 euros for in-flight duty free shopping. However, we lost close to 1000 dollars as a group when we chose to fly Lufthansa rather than a less expensive airline. We were very uncomfortable throughout the flight, having to hold my daughter in my arms for over five hours. We are are still very upset that the crew blatantly lied to us."
Pros: "This flight was 11 hours and I could have lasted another 2 or so hours."
Cons: "The lady who checks paperwork for animals at the front desk with Luftansa Airlines was uninformed and didn't know what she was doing as well as unnessarily rude. MY large dog was on this flight and after several employees had looked over my forms for him she came out nowhere and threatened to not allow my dog on board due to faulty and incomplete paperwork! I instantly went into a nervous condition of the sweats and scrambled to prove her wrong. When I asked again what was wrong with my (actually legitame paperwork) she just told me that at this point it didn't matter and that she would allow me to fly even though I was at risk of quarantine aty destination. I wasn't happy about this and asked again why there seemed to be an issue and she was unhelpful, handed me a business card for the USDA and told me that I was lucky to get away with her travel mercies for my dog. I had visited a USDA certified veterinarian and she hadn't given me the opportunity to prove this. I was confused and annoyed and while the other employees could see this about me, they apologized on her behalf. I really wish I had gotten this woman's name and work station so I could follow up with her and inform her on a few things. Other than that I love working with and flying Lufthansa airlines!"
Pros: "Crew frequently visited with wa"
Pros: "The service was good. The food was average. I liked the complimentary wine."
Cons: "They lost my bag. Huge problem."
Pros: "Nothing"
Cons: "Seats are too close, no under storage. Very old and dirty plane. Old coffee stains on tray board. Just filthy"
Pros: "Movie selection"
Cons: "Not enough beverages and the air conditioning wasn't working and made it really uncomfortably hot for most of the flight and it was miserable. Sorry just being honest"
Pros: "The A-380 Airbus is worth the whole trip. What an aircraft! Next trip , I will look for this plane when booking. Servive on Lufthansa - great and the staff is so cheerful and helpful."
