Airline reviews

Pros: "Free food, relatively spacious"
Cons: "more food!!! REEE!!!"

Pros: "Crew"

Pros: "Wasn't awake, can't say"
Cons: "Probably it would be nice to have a bit bigger screen with general information about the flight and local time"

Cons: "The TVs in economy class weren’t working and it was an 8 hour flight so it would have been nice to have some entertainment during that time"

Pros: "Crew was great. Phenomenal even."
Cons: "Economy seating, so hard to complain, I got what I paid for, but 1-2” more between seats would have kept my knees out of the lady’s back in the seat in front of me..."

Cons: "You could have had my luggage arrive. Now I don’t know where it is"

Pros: "The flight was good. Fairly good food"
Cons: "Made me check my bags on my way back for no reason"

Pros: "The movie"
Cons: "More space! The crew could have been nicer"

Pros: "Crew was kind and gracious."
Cons: "Hand carry was checked 3 different times. Goes to show that Swiss staff doesn’t trust its colleagues to determine if the bag passes muster."

Pros: "Responsive excellent crew."
Cons: "Long waits to get to the bathroom. Plane dated."

Pros: "Economy class had a bit wider seats. Included dinner, beverages, and breakfast plus snacks . Happy with Swiss Air."

Cons: "The seats in the economy cabin are cramped together. If the person in front of your leans back you are almost trapped in your seat. There is little leg room and the cushioning is not enough for a long distance flight. There is no boarding control. People just line up and get on the plane in any order."

Pros: "Customer service excellent even though I was in the economic class they made me feel first class!"

Pros: "Efficient, excellent staff and service, beautiful plane"
Cons: "There was a nearly impossible connection time in Zurich."

Pros: "Flights attendant proficinal , food was great , first time experience ice cream on airplane served. Seats are comfy and wide , much space between seats compare with other airlines."
Cons: "Nothing"

Cons: "Boarding took way too long. Plane left almost 30 minutes after scheduled time."

Cons: "No leg room very uncomfortable"

Pros: "food was great in economy"
Cons: "the 7 hour transit time"

Cons: "I booked two tickets but could not pick seats for my partner. We ended up in bad seats next to the bathroom."

Pros: "Cabin crew were friendly, efficient, courteous Refreshments generous and excellent. Good movies."
Cons: "Rather than boarding economy passengers by row number, there is a free-for-all at the gate, and tedious blockage in the aisles as passengers wait for others to place carry-on luggage. More leg-room than United, but still a bit crowded for tall people. VERY BAD DESIGN of arm-rests, which do not go up all the way into the seat but instead jut out at an angle."

Cons: "Entertainment screen didn't work properly to rewind & fast forward. boarding time was printed as 1 hour prior to takeoff but occurred 20 min. prior. pleasant crew and decent food."

Pros: "On time and standard service."

Pros: "Food was good and staff was nice."
Cons: "Touch screens didn't work very well, poor entertainment selection compared to other airlines, poor sound quality"

Pros: "Clean, modern plane, friendly and attentive crew"
Cons: "Cramped space in economy!"

Cons: "The airline changed a seat reservation after I paid for it. The Swiss support staff told me on the phone they would call me back. They never called back. I called again and was told the seats are changed and I can’t do anything anymore. The return flight seats also disappeared from the reservation. I had also paid for it. The support staff when I called again put back the seats for my return flight. I tried to check in online. Not working. Tried at least 50 times. Not working. Called the support staff. They told me to call the check in support center. I called the check in support center at least 50 times where mi was told the staff are busy and could not answer the call. I called at 6:00am next day where I was told by the check in support staff that my ticket had an issue which they did not know exactly what was the issue but prevented me to do a check in. I drove more than 2 hours to the airport where finally I could check in but I was told that my return flight seats had disappeared again. They managed to put them back again. I hope this time it’s finally ok. The support staff on the phone told me I could get reimbursed for the seat reservation I had paid for for the on going flight. The Swiss staff at the airport told me there would be no refund. Swiss is terrible"

Pros: "The crew was excellent. They were very efficient and went about their duties without disturbing the passengers."

Pros: "I hope this carrier grows by leaps and bounds. The plane was new & clean, the pilots executed flawless takeoff & landing, the flight attendants were friendly to a fault, the plane left on time & arrived early. Round trip Orlando-Venice was $980 round trip. The only niggling detail was the somewhat limited selection of movies."

Pros: "Swiss choclade"

Pros: "Friendly service, superfast check-in"
Cons: "The entertainment remote was not working and the crew member could not fix it. Indicated that his happens and that the planes are supposed to be refurbished within the year. The screen was the most user-unfriendly I have seen in a long time"

Pros: "Once staff arrived all went well."
Cons: "The flight was scheduled for about 1pm and we arrived with another connecting flight to the Athens airport at 8am as that was our only choice. No staff arrived until 11am to check people in and take baggage. We were flying business and would have liked to check in earlier and make our way through security to the business lounge but could not and had to wait for three hours. It would have been nice to have one person on duty."

Pros: "Very pleasant and friendly attendants. Food good, you'll never feel hungry! Love the chocolates!"

Cons: "Slight delay."

Cons: "Cervise was not so good was waiting almost 3 hours on check in"

Cons: "Flight from Barcelona was delayed for 2 hours, so we missed the flight from Zurich to New York."

Pros: "Services"

Cons: "Checking bags took longer than I would have liked."

Pros: "It takes two minutes to get to a live operator when you call. Simply amazing."
Cons: "The flight from Nairobi to Zurich starts in Nairobi, flies an hour south to Dar es Salaam, you then sit on the tarmac for an hour, then you fly north for an hour until you get back to the starting point. I would think they would save money if they flew an empty plane down to Dar es Salaam, picked up those passengers and then flew back to Nairobi. No way should an 8.5 hour flight take over 11.5 hours. Plus my screen didn't work for one of the flights, nearly 12 hours without entertainment was BS. No real variety in their meals either. The first leg had a main meal of beef and potatoes as the meat option, same option for the second leg."

Pros: "The ambient being so relaxing felt asleep all the way to Zurich."

Pros: "Courteous staff,"

Pros: "The movie selection was good and I found a new series to watch. The food was good. Liked the cheese and chocolate."
Cons: "Wish I had more leg room. The long flights cause fluid build up in my legs which was very uncomfortable for eight hours."

Pros: "The service , the hospitality and kindness"

Pros: "Everything is excellent"

Pros: "Entertainment and food were excellent, and the crew was pleasant and helpful. The small extras were delightful - i.e. warm cloths at the end of the flight! Overall, I think Swiss is a very good airline."
Cons: "On a long flight like this, the seating is still too cramped. We are not large people, and nine hours in those seats is difficult, even with considerate 'neighbors'. The seats are just too close together. This is an airport comment - Deboarding to a bus, then a walk to the train/tram, then security, then another walk to the gate - we barely made our connecting international flight."

Cons: "The handle of the pull-stick that slides into the suitcase was broken off with the pull-stick sticking out of the TUMI suitcase. Used a pen point to release it and get it back into the suitcase. No handle so it was impossible to drag the suitcase. The ground personnel representing Swiss Air at the Boston Baggage carousel was a novice, had never filled out a baggage claim form before. Told me they would phone me. I am a bit skeptical about this claim. Not sure if it was Swiss Air of the local ground personnel who damaged the suitcase."

Pros: "Time of flight"
Cons: "Food and entertainment were not good. Person next to me smelled bad"

Cons: "An hour late, not Swiss fault but Captain continued to broadcast 5-10 minute delays. Just say it's going to be an hour, then we can all turn our phones back on and go to the lavatory."

Cons: "Flight delayed four and half hours. In this time not acceptable. I am not sure if I will fly Swiss again."

Pros: "The seats were actually more comfortable on this short leg than on the much longer flight back to Boston. And the Swiss chocolate was good."
Cons: "Having to pay for a second checked bag. And the refreshment (I think it was supposed to be ice cream) was awful. Also, I think it was the young pilots virgin flight. The jerky take off and bouncy initial flight was capped off with an approach to the runway for landing that was very scary, much too fast and wobbly. Thankfully the plane was pulled back up into the air, just before touch down, circled for ten minutes, and retried the landing. This time perfectly smooth and successful."

Pros: "Was fed dinner and breakfast on an overnight flight, all was very good. Pillows and a blanket made it a very comfortable flight"

Cons: "Nothing"

Pros: "great flight, good social distance and empty seats in between"
Cons: "really nothing, it was as good as possible in these times"

Pros: "Delta is the airline to fly if you have to fly (like I did) during a pandemic. They made sure at every turn we felt as safe as possible. They had passengers distanced from each other the whole time, handed out sanitizing wipes as we walked on the plane, made sure folks kept their masks on, gave us individual little baggies with snacks and water bottles that also had individual hand sanitizer packets. I felt so much more safe flying Delta on my way home to Hawaii in July than I did when I flew American Airlines on my way to the mainland in June."

Pros: "Comfort+ seats are affordable and give me the leg room I need as a 6'3" adult."
Cons: "Seems like Delta provided free upgrades to families with small children in Comfort+. This impacts the flight comfort for us paying customers. Recommend readdressing this policy and not placing small crying children in Comfort+ for free."

Pros: "Short flight and no problems."

Pros: "It was ok"
Cons: "Seat the family together"

Pros: "Nice smooth flight."
Cons: "Tiny seats. No entertainment offered."

Pros: "Funny crew members and very friendly captain"

Pros: "Met expectations; except for treatment of an oversized passanger, which turned out good in the end."
Cons: "Refreshments"

Pros: "Delta’s crew is the best part about flying delta!"

Cons: "Both Copenhagen and New York need to go a better job on the flow of passengers through Passport control."

Pros: "Food, timeliness, comfort"
Cons: "Not sure"

Pros: "Everything but the plane The crew and gate staff were well trained and professional. Very impressive the way they smoothly guided us into and out of the plane. Especially their handling of a few snafus. Well done!"
Cons: "The plane was older and not as nice as the one from ROA to ATL. That said it was still better than the puddle jumper jets used by United and US Air."

Pros: "The fact that we left on time given the thunderstorms in the area, and landed on time in Atlanta was amazing. Congratulations to the crew!"
Cons: "Not surprised there was no WiFi, but it would have been nice as more aircraft of all sizes are now equipped with WiFi."

Pros: "Seats were horrible, we all booked together and a bunch of my group got bumped to a different flight."

Cons: "Seat didnt recline and very tight between passenger seats"

Pros: "Pilot and his ability to maneuver the turbulence. Also variety of snacks."
Cons: "Felt hot in the plane."

Pros: "Boarding was easy. No issues. Friendly staff. We had to fill out customs declaration forms but didn’t have a pen. We asked stewardess for a pen and they didn’t have any left. She said to borrow from a neighbor which I thought was rude. We don’t know our neighbors. If a flight requires filling out a form, they should provide enough pens to do so."
Cons: "Not enough pens"

Cons: "Cramped"

Pros: "More room and comfort than American Airlines."

Cons: "Very little leg room."

Pros: "Boarding was quick Flight experience was good"
Cons: "Leg space was less Take off got delayed"

Pros: "On time, pleasant and friendly flight attendant, no unexpected issues or problems."
Cons: "Grumpy gate attendants at YUL! Could not hear the captain’s comments over the PA system. Shouldn’t the volume be checked every so often? We were offered only water or coffee, bad enough, then there was no milk or cream on board, so water or black coffee... not very impressive! And there was no entertainment so I’d rate that zero but the scale only goes as low as one star."

Pros: "The flight attendants gave great service"

Cons: "plane delayed over 3 hours."

Pros: "The Delta desk attendant at CVG was unable to come up with another flight to get me from CVG to Colorado Springs on 6/13. There is nothing to like."
Cons: "See comments above."

Pros: "Food was good and so was the movie selection"
Cons: "Boarding was slow and the interviewers were disrespectful. Also I was upgraded last minute and I could never understand the system by which upgrades to first class are granted. Just because I used my points to buy the flight I wasn’t eligible for an upgrade to the one seat left in first class even though the flight is full and I am the first one on comfort+ upgrade list and there was no one on delta one upgrade list."

Pros: "Never got ticket or email or booking number. Called my bank they said charge still pending. I asked if they could cancel. Bank said yes. Told them to cancel and rebooked throught Delta website. Got eticet. But charge was not cancelled. At airport I had 2 tickets. Working with bank. Today gate agent gave me 1st ticket number. Used Kayak and delt never had this issue. Email not changed or misspelled."
Cons: "No eticket or booking number recieved."

Pros: "The seats."
Cons: "In typical Delta fashion they boarded, deplane, board it again and then beat the plane. Blamed it on weather even though a full maintenance crew was beneath the plane in the entire time and, for the coup de gras moved a new flight an hour later 30 gate down. Classic Delta hopefully they'll be out of business in a year"

Cons: "Nothing"

Pros: "Ice weather and flight cancelled, but they waited until the last minute to cancel it."
Cons: "Ice weather and flight cancelled, but they waited until the last minute to cancel it."

Pros: "Everyone very friendly and courteous."
Cons: "Snacks are very small quantity and often stale"

Pros: "it was great experience"

Pros: "Flight attendant was excellent and pilots did a great job with weather"
Cons: "nothing."

Pros: "No problems curling up against the bulkhead and going to sleep. Crew was very considerate about not broadcasting messages to awaken travelers during this overnight flight."
Cons: "Was a bit warm but in a full plane what can you expect?"

Pros: "Smooth ride. Delta got everything right from takeoff to landing."

Pros: "It got me home."
Cons: "Although I paid for a first class ticket I was seated in coach. The plane was a commuter jet, and I suspect that Delta added one or more rows of seats because even though I'm of average height and less than average weight I had no leg room at all, and the hip room was minimal at best."

Pros: "Nothing."
Cons: "Reservation. Checkin. Seating. Flight."

Cons: "Entertainment system was not working."

Pros: "Not even a bump ...seriously an amazing plane and pilot!"
Cons: "The afternoon snack was disgusting ....(not just my exclusive opinion)"

Pros: "Everything"
Cons: "Nothing"

Pros: "They were smiling and very welcoming"

Pros: "Lufthansa is always incredible."

Cons: "The in-flight snack - choice of two disappointing sandwiches."

Pros: "Spacious seat, easy charging."
Cons: "Boarding"

Pros: "Crews was excellent, always refilling water which I can appreciate so much. Keep it up! Loved the United pilot at John Wayne who came out just to say hi, let us know we were in good hands."
Cons: "Had to wait in tarmac forever from Frankfurt to Florence"

Pros: "Very friendly and accommodating"
Cons: "NA"

Pros: "There attention to detail, client comfort, friendliness, food, all was a ten out of ten. Thank you for the lovely experience."

Cons: "We were put on standby. We expected our names to be called for seat assignments but we didn’t expect we could just swipe our boarding pass and our seat assignment would show. It’s a nice feature but I didn’t like that it wasn’t clearly explained to us."

Pros: "Nothing"
Cons: "Everything, lost luggage and missed flights because of flights not making their time."

Pros: "They know what they're doing!!"
Cons: "No complaints at all!"

Cons: "I did not like the bathroom downstairs."

Cons: "The seating was poor. The armrest did not go up even so I and another passenger tried hard. I then had to climb over it to be able to get to the washroom at 86 that was not the easiest and again it should not happen regardless. Otherwise I was treated well.I was a wheel chair passenger for medical reason. Thanks Helen"

Cons: "Same as Abu e"

Pros: "Lots of movies"

Pros: "fllight attandants were very pleasant"
Cons: "n/a"

Pros: "Yes, Very good"

Cons: "I had paid for an upgrade to sit in the front of the cabin with extra legroom (row 14A). When I boarded a man sat it my seat. He had not paid for the upgrade, but the crew let him stay in my seat. I had asked him to social distance but he continued to sit right behind me bo matter which seat I moved to. He argued with the crew until they gave up and let him stay. They did not check his boarding pass or ask him to move to his assigned seat I found a different seat away from him but I don’t see the point in paying for extra legroom when the crew let’s people who haven’t paid for it sit it those seats. I felt harassed by the man and was very uncomfortable the whole flight. I am considering my next step, I think I should at least receive a refund for the upgrade I paid for."

Cons: "Inflight sandwiches"

Cons: "Everything was OK"

Pros: "Service and crew amazing friendly and went out of the way to Make u feel special even the pilots gave updates thru out the flight"

Cons: "Flight delayed, no USB port and no entertainment"

Cons: "Vegetarian meal was okay but could be more enjoyable if served with bread at start of meal."

Pros: "Great crew, comfortable seating with enough leg room."
Cons: "Provide dinner before getting to joburg, instead of a snack. Flight arrives late so dinner would be appreciated"

Pros: "Service is awesome. Food is great."
Cons: "People with short connection are affected by the 15 to 25 minutes delay."

Cons: "We were allowed to choose our seats from SFO to Amsterdam but not for the return flight. I like to be able to choise my seats when I book the flight. Choosing seats 24 hours before is not convenient when traveling for the return trip."

Pros: "Overall KLM experience is good"
Cons: "Food quality was mediocre for a business class flight."

Pros: "Crew were great, food, entertainment, seat and everything else was great as well."

Pros: "Very pleased with KLM - efficiency all round and especially the baggage handling at Schipol swhere I had 20 minutes to transfer and my baggage came back with me to the UK which is no mean feat given the hustle and bustle of such a large airport"
Cons: "No downsides at all"

Pros: "All good"

Cons: "Faultless handling of weather delay, causing missed connection and flight transfer. A well oiled machine, thank you."

Pros: "Nothing to mention"
Cons: "Crew was rude when I asked if there was a vegetarian option for the snack. I did request special meals for the trip. Even if they did not have a vegetarian option, they don't need to be rude!! Boarding was ridiculous. we were supposed to form a line and wait. Would have been a lot better if they boarded by seat numbers. Also they made me check in my fairly small and light carry on bag resulting in its contents arriving broken!"

Cons: "Landlords gave an unpleasant service! Which continued with late of 50min of the flight, they didn’t do anything to help/ to provide the passengers the answers. The food was cold It was comfort place to sit. Bad experience with KLM"

Pros: "Very pleasant, professional crew"
Cons: "Very slow check in. Mainly because other passengers obviously don't read instructions re: weight/contents of cabin bags etc. Would be helpful if there was additional staff to deal with them away from check in desk. This would mean that others did not have to queue for 25 minutes because the check in girls also had to deal with them"

Pros: "Crew was awesome"
Cons: "."

Pros: "Very friendly and helpful crew."

Pros: "Food was excellent, service from staff was friendly, and entertainment options were great."
Cons: "Not a lot of shoulder room being in the middle seat. But it had adjustments options for a lot of other things which were good."

Pros: "Interior of the plane was clean. Smooth landing."
Cons: "Pilot did not avoid turbulence"

Pros: "Sound was broken on my TV set!"
Cons: "Called stewardess twice to assist. No response!"

Pros: "Service, technology"
Cons: "Could not print by boarding card and was not allowed to board in Amsterdam"

Pros: "Boarding was quick, Flight on time....just a regular service and plane"
Cons: "Terminal 3 Manchester is not worth staying longer then necessary, loud music, crowded....old"

Cons: "Food"

Pros: "The staff were professional and friendly The food was very good and plentiful The inflight entertainment has lots of choices The bathrooms remained clean All in stark contrast with BA with who I did the same flight 2 weeks ago and all the above points were very poor"
Cons: "Nothing"

Pros: "Only thing we liked was the fact that we were able to get onto our flight at all..."
Cons: "Was not informed that checking in online is the only way to secure a seat. So, regardless of whether you book your tickets 3 months in advance or the day before, you're not actually guaranteed a seat unless you check in online. We weren't told this until we were at the airport and checked in there that we might not be able to get our pre-booked in advance flight because of over-booking from KLM. We then had to wait and see if there were seats available when boarding. Luckily, there were, but we were not sat together. Not the greatest start to our first holiday together as a couple. We were told that if there weren't seats available, they'd pay for us to get to another airport to fly out, which would have meant a huge delay on the only time off we'd get together this year and have to rearrange our pre-booked and pre-paid living arrangements for the week. All because there wasn't a lot of emphasis on the need to check in online before hand. You'd think if someone checked in at the airport, that would be more of a guarantee that they'd be flying with you that day, but apparently not. Definitely not impressed or happy with this part of the KLM experience. This is the only company that we've had this problem with, they should make it clearer that it is essential to check in online."

Pros: "had problems checking in , in that I was charged for a suitcase! I have since checked my paper work and found thad that I had paid for a case! I will follow this up when I return to the UK"

Pros: "Ground staff at Manchester very helpful"
Cons: "Information on KLM website and flight status said 50 minutes delay and was never updated with the true status. 3 hours before we took off. KLM blamed the fog at Manchester but to be honest most other flights seemed unaffected. Put up in an IBIS hotel and fed substandard food and shitty hotel room with an Aircon unit that clunks into action every 30 seconds keeping me awake. It's external so I can't switch it off. Being given a 10 Euro voucher for food at the airport when most food and a drink will cost you 12 to 15 euros."

Pros: "Thankful for coffee being served without charge. Not all airlines do that."

Pros: "Professional, welcoming and very friendly crew, well-maintained aircraft, comfortable seat and good food. Keep up the good work, KLM."
Cons: "Not much to comment on here."

Pros: "From pre-boarding, to boarding, to the food, and the attentiveness, everything was top notch! The cleanliness of the plane was only topped by the friendliness of the crew."
Cons: "The flight was marked at almost 11hrs but ended up being only 9...not a negative other than it meant not spending as much time on board!"

Pros: "Usual professional and friendly service from my airline of choice for most destinations."
Cons: "Nothing"

Cons: "Per usual, KLM can't seem to figure out the order of boarding the plane. Should be business - priority - everyone else. Instead they do priority first, and that's usually two-thirds of the passengers. Strange choice of in-flight movies; no accounting for taste, I guess."

Pros: "Loved the service...everything was excellent"
Cons: "The bus class seat was a bit narrow at the feet"

Pros: "Staff at Schipol airport were lovely and very helpful. Cabin crew were friendly and efficient. On board snack was nice."
Cons: "Elbow room is a little bit awkward and I didn't get to sit next to my fiance WE will still definitely recommend KLM though!"

Pros: "Night flight so no entertainment allowed sleeping"
Cons: "Kosher food could be improved"

Cons: "Seats were a little too narrow, and quite uncomfortable when a broad shouldered person is sitting next to you"

Pros: "It was a short flight so it was O.K."
Cons: "Boarding was odd. Go to airport early and counters were not open, did on line check in so was able to avoid the self check in at airport. Also self check in luggage seems confusing with no ground crew to help. It didn't affect me but lots of confused passenger."

Pros: "The crew was very pleasant and professional. toilets were very clean adequate overhead space"
Cons: "Very uncomfortable seats in Economy Comfort. Legroom and recline were OK but the seats were extremely narrow. No evening meal and breakfast was minimal"

Cons: "The crew on the Lagos Amsterdam route (in economy) are particularly unfriendly and brusque. This is my experience each time i fly this route in economy"

Cons: "I was"

Cons: "Last plan of the day waits for all transit passengers! Never take the last plan out of SAS hubs anywhere if you want to avoid delays..."

Pros: "Friendly staff"
Cons: "n.a."

Cons: "Boarding was a little rough as the announcements in groups to board was not clear and lots of people got in line that should not have. - causing delays and frustrations. Handled poorly by gate team"

Cons: "Small, uncomfortable seats which is tough for a long fight."

Pros: "boarding is different and they were talking over pa announcements at heathrow so you could not hear what to do. you go through one ticket agent to the down stairs to another ticket agent. everyone knowing what to expect crowded around the second ticket agent and there because of that forget about boarding by row or zone you couldn't get throught the crowd. plus the second ticket agent was right next to the downstairs escalator so people coming late got on before us."

Cons: "to realise at the airport that they will charge me 70 EUR for one luggage for one way only is outrageous! it wasnt clear at all that there wasnt luggage included in the price of the ticket... all of my previous tickets bought via kayak and priceline were also with luggage included and we have understood the given price as including luggage! i find it very negative and very bad experience and feel robbed, this is not acceptable business approach. my suggestion is that you will refund me the extra cost for the luggage. thank you."

Pros: "Easy embarkation, helpful staff."
Cons: "Shock to discover that suitcases were not included in price of tickets purchased online. We had to pay the equivalent of $100 (australian) per case. My seat was extremely u comfortable as the cusihion was misshapen. The male passengers seated behind us were drinking alcohol and became loud and garrulous, making the trip most uncomfortable and unpleasant."
