Pros: "Mmmm"
Cons: "Superrrrrrrrrrrrrrrrr"

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: "The crew was polite and helpful. The wine was free and each seat had it's own screen with a good assortment of movies and TV shows."
Cons: "The food could be much better. Although coming from Sicily it's tough to compare."

Cons: "Legspace in economy class was probably good back in 1975, but in 2019 not acceptable anymore"

Pros: "A nice crew n my seat next to me was empty so I can sleep well..."
Cons: "Maybe give every passenger a bottle of water..."

Pros: "Everything!"

Cons: "When I purchased the ticket I did not know that I have to pay for my bag. It would have been nice to know about this in advance"

Cons: "To my shock, my boarding pass while scanning to enter the aircraft was rejected with wild flashing red lights saying my trip was cancelled. Someone else was given my emergency row seat, booked and confirmed 24 hours ahead. It was a full flight but I got a middle seat and continued my long journey home from Kenya"

Pros: "i ordered and paid for business class but the return flight from israel had no business class Had a miserable flighIshould be refunded"

Cons: "The plane was ancient. offer wifi- at least be able to pay for it. charger outlets."

Pros: "TV screens and movies. Food was great."

Cons: "They lost our bags for the second time in 4 days. Both originating flights were late starting and made for impossible connections! Is Swiss ever on time? Frustrating for sure!"

Cons: "Because we missed our connection on our incoming flight, due to a delay leaving Newark by Swiss, Swiss cancelled our returning flights. So when we got to the airport on our return day, we were not booked on any flights. We were required to stay overnight and take a United flight home. Will avoid Swiss in the future."

Pros: "A very friendly and attentive crew and a decent meal. Comfort is still iffy in coach but better than most American airlines. Good selection of movies to pass the time."
Cons: "Seats in coach are cramped and some have an electrical box under the seat in front of you, so there is no room for your legs or carry on bag. Bathrooms keep getting smaller to jam in more seats."

Pros: "The booking to a new flight was seamless."
Cons: "We had to take a different flight on Lufthansa which had a whole list of it's own problems."

Cons: "I chose my seat online and when I got to the gate they changed my seat to the way back of the plane"

Pros: "Swiss Air is great."

Pros: "3"
Cons: "Everything"

Pros: "SwissAir is the best airline ever. Modern, comfortable plane with space - excellent for long haul trips. Zurich is also a great airport in which to change planes."

Pros: "Food."
Cons: "There was not hot tea/coffee offered with a sandwich."

Pros: "Short flight and they handed out chocolate"
Cons: "They announced that carry-on suitcases must be checked to accommodate a much smaller plane This only applied to those stupid enough (us) to comply"

Cons: "We missed our flight going to Geneva from new York and so automatically lost the return portion of our flight. So had to totally rebook. The people at the Swiss air counter were not very helpful."

Pros: "flight left on time as schedule and the flight staff was absolutely courteous."

Pros: "The flight was delayed from Newark to Zurich but they were able to rearrange my connecting flight before landing. The Swiss staff were very courteous and amicable. The food was also tasty."

Pros: "Very professional!"

Cons: "The boarding process is very uncomfortable as the passengers are asked to board the plane without any specific order, regardless of where they’re sitting, instead of boarding them by groups."

Cons: "Space for legs seems to become smaller and smaller. In EL AL (flight back) space was wider."

Pros: "The seats were comfortable considering they were middle seats. The food was quite good and the entertainment selection was also good."
Cons: "Boarding was later than initially said and I did not know why"

Cons: "Ok, old plane."

Pros: "Just another flight, nothing special."

Cons: "Bathroom not clean"

Pros: "Plane was comfortable (for a plane) and the staff were polite and efficient. The flight made up lots of time and the in flight snacks were very welcome."
Cons: "The flight was very delayed, and the communications from Swiss was lacking. In fact their app thought the flight had taken off and landed on time?!"

Cons: "I could not obtain a refund."

Pros: "See below"
Cons: "We got to Rome airport 4 hours before to not miss flight! They booked us with 45 min to connect in Zurich. Then flight from Rome kept getting delayed with no explanations. We got to Zurich with 30 minutes to go. We literally ran to get to gate E. We got no help from Swiss employees and got to our gate with 10 min before flight. They said gate was closed. Went to transfer desk, next flight was next day at 1 pm. Missed very important meeting at work that I had planned around for months. Very upset and disappointed. Felt they could have helped us a lot more and got us on our flight."

Cons: "Online checkin was tricky. No help for online form which were probably translated from another language . Took me a few guesses to figure out what the 'valid for' field actually is... Departed 30 minutes late"

Cons: "On ticket it said time between flights was 1hr 25min, but as soon as we got off the plane we had to RUN through Zurich airport, where 1000 other people were all trying to funnel down the single escalator to Passport Control, to get to our gate. Then we had to wait in another Passport Control. TERRIBLE and stressful. The actual flight was fine."

Pros: "We arrived early"
Cons: "No entertainment, no pillows or blankets, uncomfortable seats"

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: "I had no idea i would be charged for just one check in bag!"
Cons: "I had no idea i would be charged for checked in bag! Scam!"

Pros: "Food"
Cons: "Lack of screen for watching movies."

Pros: "The planes were clean and in good repair. The staff was well trained, polite, efficient. The food was excellent. Our entire experience with Swiss Air was the best in ten weeks of travel we have completed this year."
Cons: "There was nothing that disappointed us in our experience with Swiss Air."

Pros: "Very impressed with snack: good tasting quiche with biodegradable packaging and no plastic utensils. Thanks for being so green! On time flight."

Cons: "We loose our flight and they didn't give us any chance to save some money on a new ticket."

Pros: "Very good service on board"
Cons: "Crammed into middle seats both way. Many/Long lines in ZRH/SFO"

Pros: "Everything"

Pros: "It was great to have timely service where the staff made sure you were comfortable and pleased with the flight. Great entertainment on board with no technical difficulties. Fantastic experience!"

Cons: "Ice cream snack."

Pros: "Ok food and ok entertainment"
Cons: "Plane was very hot and there were no air conditioner valves so we had to sit in a hot plane for thirty minutes. Seats didn't recline at all so sleep was out of the question. Just a very miserable flight overall."

Pros: "Kind and efficient service. Help to board and disembark Good communication. Great customer service."
Cons: "It took some time to get our gate-checked wheel chair, but I have to say, they went out of their way to help us find it."

Pros: "It was OK experience. Nothing special."
Cons: "I was overcharged for luggage. Was not given the chance to pay when checking in online so was charged top rate for 1 piece of hold luggage at the check in desk. A flight that was a reasonable cost became expensive."

Pros: "Plane was new and good"
Cons: "Flight was 4 hours delayed"

Pros: "Very old aircraft. Looked extremely run down and many things were broken."

Pros: "Sarah the Cabin Manager was amazing."
Cons: "The business seats are horrible"

Pros: "The crew."
Cons: "The aircraft: too old! No charging ports, entertainment system horrible. The food was not super."

Cons: "Heathrow is the worst airport when you have a passenger who needs a wheel chair."

Pros: "I reached my distanation safe"
Cons: "Newer and cleaner plane better entertainment"

Pros: "Crew was great, plenty of food."
Cons: "The announcements ran a bit long toward the end of the flight. Quite a bit long"

Pros: "Warm welcome, on time and comfortable"

Pros: "On time, good service."
Cons: "Ran out of vegetarian options. Staff slightly inattentive and rushed when dealing with clients."

Cons: "Generally, it was just good."

Cons: "Are you kidding me? Plane was delayed and we miss the next plane. We were in airport 14hr. Still in London."

Pros: "Kind and caring staff"

Pros: "Crew and seat comfort."
Cons: "No entertainment, not even available if you paid."

Pros: "The privilege of getting business class perks"
Cons: "The business class seats are economy class seats with the middle seat blocked, the leg space are same as economy."

Pros: "Cabin relatively new. Leg room in economy adequate. Cabin crew pleasant"
Cons: "Zero checked baggage allowance!! CDN$70 for first checked bag if booked before hand, $113 per checked bag if paid at airport!! All food and drink on this 4 hour flight from London to Santorini must be paid for!! No peanuts. No cup of soda/pop. Maybe a small plastic cup of water. Bring your own iPod or tablet. No seatback entertainment! On Airbus with very limited overhead hand baggage capacity. Roundtrip cost of this 4 hour flight CDN$800 per person booked 3 months in advance, not much less than transatlantic flight of almost twice the time from Toronto to London on Air Canada Boeing 787 with loads of overhead luggage capacity, free first checked bag, 8 inch screen seat back entertainment system, charging ports, one major meal with wine / beer, unlimited pop, plus snack. A real shocker to get Ryanair amenities on this British Airways flight which was no bargain."

Pros: "Nice aircraft! Very modern."

Pros: "Entertaiment"
Cons: "The crew could be quite curt at times"

Pros: "I chose British airway relying on safety record depite being comparatively expensive."
Cons: "The outer seat arm was faulty. It couldn’t be folded back, so getting out or in was very difficult. It is certainly risky in case of emergency . I asked the hostess to report it. Nothing complementary offered to passengers .Other reputable airlines do, such as a drink , or chocolate bar ."

Pros: "The fight was ok."
Cons: "It took us two hours to go through customs. Th luggage people had no idea where our luggage was. As a result it cost us an extra 30 lbs because our cad drive had to wait an extra 2 hrs."

Pros: "Customer service."
Cons: "Entertainment need more movies"

Pros: "Both flights were on time. Funny comic relief safety film kept my attention. Friendly cabin crew member gave me a hot tea for free."
Cons: "No breakfast served in economy to my disappointment, there was no mention of that when I booked with Kayak. The seats are not too comfortable, with little legroom. The BA app did not show gate information when I needed it."

Pros: "The crew were friendly, professional and extremely pleasant."
Cons: "I’m not a fan of the constant PA’s during the descent. Playing a video about arrival procedures for an airport is extremely superfluous. Nobody pays attention and you just have to follow the signs when you get there."

Cons: "Rude staff at the airport. Short overlay did not have enough time to get our bags and checkin again that was ridiculous to have to check in again!"

Pros: "That we made it to New York"
Cons: "Being selected for extra security because I am American was upsetting. Worst turbulence I ever experienced the pilot didn’t even try to avoid it. Finally landed stuck on the ground in the plane 50 minutes before we got to the gate. Plane landed at 420pm and I didn’t get my bag until almost 7 pm. This caused me to have to throw my suitcase away because I couldn’t make it to my connecting flight in time. Worst travel experience ever"

Pros: "As a British citizen living in the US, I have always rated the quality of the service BA has given"
Cons: "Flight was delayed from Manchester to Heathrow by 30mins. OK understandable. On arrival to Heathrow we sat on the tarmac for an hour and a half as apparently there was not enough staff to connect the plane to the gate.The computers to tell us where our connecting flights were down so they could not tell us which gate to go to. When we finally disembarked, I was not allowed to my gate despite it being in the same terminal and having 40 mins to go.I was directed to a BA desk to get another flight. After 15mins waiting here the staff were rude and announced they would be closing. I finally was directed to departures to be told the only option was the same time tomorrow."

Pros: "Me and my husband were upgraded from world traveler plus to business class, which we are thankful for"
Cons: "We were unable to order special meal online and were told to contact onboard crew for meals. When we contacted them inflight, they said they don’t have meals!!! And we were left to starve the whole night, while food was served for all around us. The really shocking thing is none of the crew had the courtesy to offer some snacks or bread. These especially when we were seated in business class!"

Cons: "Luggage did not follow me. Still without."

Cons: "There was a new born next to me and actually it was difficult to sleep."

Cons: "Flight canceled want able to rebook"

Cons: "As a Kenyan Passport Holder living in Canada on a PR status was denied right to travel to Kenya via LHR transit. WHY ? will you help us with our rights what compensation will help to alleviate the pain"

Pros: "More seat room. 18inch width. Smaller cabins. Soooo quiet."

Pros: "Crews were very polite and helpful when I had trouble with my carry on luggage. Cheerful despite the overnight flight. Unfailingly polite when asking people to do things that had already been asked or explained several times."
Cons: "Seat was uncomfortable--something about the contour of the back. Pasta with vegetables was mushy. Not enough movie choices."

Pros: "The seats assigned."

Pros: "Crew members were all very nice.the flight was on time."
Cons: "The breakfast served before landing was no good,"

Pros: "No complaints about the flight. It was so short that we didn't even have time to get a drink or snack. Quite a bit of turbulence but I think that might be typical."
Cons: "Turbulence."

Pros: "did not get notification about early flight departure, I do not expect great airline food but the food was TERRIBLE ! Staff was not informative about much nor did they serve with a 'smile""
Cons: "see other note"

Pros: "Overall flight better London to Beirut l"
Cons: "Long wait over"

Pros: "We made it safely"
Cons: "The flight was delayed The seats were very uncomfortable in priority section. The entertainment was not working for a good 2 hours, untill the engineer reset the system. No USB or outlet ports for charging the devices. Excuse me, but it is 2017."

Pros: "Comfortable and classy."
Cons: "No comment"

Pros: "Smooth and nice flight. Crew was friendly and attentative."
Cons: "I found it surprisingly coincidental that both my wife's and my checked bags did not make the flight to Santorini. Of course, given how the process in dealing with Kayak and this booking, it did not surprise me. Any calls or customer service related questions were handled as though we were 2nd class citizens. I've never been treated like this traveling, but always the attitude came from "oh, you booked this through a discount site" and then I was handled accordingly. I booked it through Kayak for ease as I planned a 7-city, 21 day trip around the Adriatic. Now we'll do our honeymoon without a wardrobe change, filing claims for the contents of our bags, as no one can tell us what happened, or where the bags are, and we're about to depart for our next city. Never, NEVER book a trip from a 3rd party. The seats next to the toilets that don't recline, attitude from airlines, now my first lost bag in 10 years (I fly 3 times a month, too)."

Pros: "It arrived in Greece on time, good landing."
Cons: "Arrived in Greece for daughter's wedding. They lost all 14 family members luggage for 4 days!! Received our luggage 6PM the night before wedding, which caused terrible distress for the Bride especially and all 14 family members. Imagine being in Greece for 4 days with nothing but the clothes you traveled in. Horrible!! Will never buy a BA ticket again."

Cons: "I thought I was supposed to get a free meal and was never offered that or even a complimentary beverage. The flight attendants allowed a group of four passenger to stand during almost the entire flight in the aisles and in my row, making it difficult for people to get around them and didn't allow for an enjoyable flying experience."

Pros: "Sandwich was tasty, but had to pay for it. On short flight, that's not a big deal."

Pros: "Great service and experience."
Cons: "The boarding was a little long."

Pros: "Hard to say after they lost my luggage, cramped space, no leg room because of electronics box under seat, then the person in front of me decided to recline all the way back on a 12 hour flight. So I lost my luggage, and had some smelly stranger practically laying on my lap for 12 hours. Talk about insult to injury!"
Cons: "They forced me to check my bag, even before I boarded the plane and said there wouldn't be any room. Then they lost my bag. Worst thing I ever did was listen to the lady at the ticketing booth! Also, the way they do boarding is a total joke. All they care about is their first class passengers. For the rest, it's a free for all! Terrible, even Southwest has more organization! Sputhwest might not have assigned seating, but they're much more organized and significantly cheaper. How do you lose someone's luggage British Airways?!?!?!!!"

Pros: "The entertainment was great, I just watched movies the entire flight and had a great time."
Cons: "Needed more water but I guess they were busy with some sick passengers."

Pros: "Stewards were very friendly"
Cons: "Need more opportunities for drinks, water. Did not board the back of the plane first."

Pros: "No comment."
Cons: "Flying in and flying out was a headache! Both times, the flights were delayed, therefore causing me to have to miss my connecting flights "BOTH times!!!!" I had to rebook and reticket my luggages throughout both travels! I will NEVER EVER book with Bristish Airways EVER again! Worst experience ever thus far! Worst part was that I had my elderly parents with me and I had to continuously make changes because of the flight delays, which put all of us in extreme stress! Made me sick to my stomach of how unprofessional BA staff were when it came to accommodating us due to their delays."

Pros: "The crew was wonderful , the seats very comfortable , breakfast very reach I felt my self booking first class not economy It is the best trip"
Cons: "Nothing"
