Pros: "Swiss flight zrh to ord was great! Great crew, excellent food and service, comfortable seating, great entertainment."

Pros: "Throughout the long flight, the cabin crew was excellent. They were attentive and friendly. They avoided interrupting quiet time and rest time by keeping off the PA system (well done). The food was fantastic. We were lucky enough to get some business class tickets with points, and the food was amazing. Wine was excellent. This team was quite solicitous of my parent with reduced-mobility. And the bathrooms stayed clean throughout the flight. find this is often an areas where many airlines fall down. And it's too bad, because while I'm 100% sure it is no fun to clean a toilet while in flight, it is a really a big negative for the customers. Overall excellent attention to detail, with a cheerful and "can-do" crew that kept the plane "proper" throughout the flight and provided seamless service. Good stuff. Will fly again."
Pros: "Excellent, super-friendly crew, excellent meal"
Pros: "Food was better than some other long-haul flights I’ve been on. Plane fairly clean and comfortable."
Cons: "Entertainment options more limited than Delta or Virgin, who I’ve usually flown intercontinental. Boarding in Zurich was a mess. No order to it and they didn’t start boarding until 20 minutes before takeoff. Nearly every intercontinental flight I’ve taken needs closed to 45-60 minutes to do a full board. Sure we made up the time in the air but the process to get on the plane was frustrating."
Pros: "On time departure; easy flight; seating was spacious"
Cons: "The extra charge for a bag!!!!!!!!!!! Would rather fly Southwest or Jet Blue or others that allow a mid size carry on"
Pros: "I really liked the "About my flight" application on the viewing screens because it always gave me an idea of what we were flying over and how much longer we woulld be in the air. The food was excellent and I was pleasantly surprised that I could have wine with dinner or any time the attendants offered beveragess. The attendants were always professional and helpful. They all were fluent in English as well as several other languages. It was a nice touch when the attendant wore white gloves when he or she was collecting passengers' trash after meals and/or beverage service. I loved the cheese that was served at dinner."
Cons: "My seat was a little confined when I put my carry-on bag in front of me on the flight to Zurich, but it was roomier when I stowed my carry-on in the overhead compartment on the returtn flight."

Pros: "This was my first time flying on Swiss Air. Beautiful aircraft and a very friendly crew. Food was good and our flight was on time. Lots of options for in-flight entertainment."
Cons: "The boarding process was not ideal. This was our first time in the Zurich airport and we were not aware of the passport check at the gate. There were no signs and several passengers tried to board without the stamp only to be sent to the passport check line. Very frustrating. Also, there was no organization so everyone just rushed forward when boarding was called. They should consider boarding by rows to make it a more orderly process. Finally, there was no leg room at all. I realize airlines are trying to squeeze every passenger in that they can, but this was ridiculous. I'm 5'11" and my knees were pinned against the seat in front of me."
Pros: "crew was great. Food was excellent. Bathrooms in good shape."
Cons: "No internet. Very slim choices for entertainment."
Cons: "Not enough leg room"

Pros: "Food, service,"
Pros: "I have been flying to Greece and back many years now. I have never seen,such comfort in a plane,such great service,so many snacks and meals,and the crew was coming by every 30-45 minutes for water. We were served Swiss chocolate and also the best ice cream I have had in my life. Best flight and best plane I have flown in my life."
Pros: "The food and service was wonderful."
Cons: "I was disappointed that there was no plug-ins to charge electronics."

Pros: "Attentive crew"
Cons: "Long wait for baggage at destination"

Pros: "The warm professionalism, quality of service, and attention to detail by the flight crew was outstanding."
Pros: "Food was amazing, boarding was smooth and it went fast, and the crew was very nice."
Cons: "The seats were uncomfortable and if someone reclined their seat was about an inch away from your face. So if you had anything on your tray it was slammed into you stomach. Also it was so hot on the plane felt sick the entire way. Asked twice to turn down the heat nothing really happened. Missed the individual fans."
Cons: "My bag lost it's tag either in Minneapolis or on the way to Chicago and was re-tagged. It then took 5 days for the bag to arrive at my final destination. Swiss airlines didn't answer any phone calls, didn't respond to email messages sent through the Swiss air website. Had to get an outside agency involved to recover luggage."
Pros: "the service was good"
Cons: "i bougt my ticket on Swiss Airlines. Originally only my frist flight was operated by United. Then something happened and the flight went late and i lost my connections. i ended up flying 24hs late (FROM NY), had to payed a hotel, and my next flight was with United (AGAIN). I really wanted to travel with Swiss, because they have a Ski bag included on the luggage. I ended up paying extra bag in United."

Cons: "Smooth on time flight"
Pros: "The seats were ok."
Cons: "The flight was delayed over 3 hours so I missed my connection in Chicago to Seattle. I’m now stick in Chicago overnight and have to be on a 6 am flight tomorrow. The Delta staff at LaGuaurdia was extremely rude and not helpful at all. Hate Delta......"

Pros: "I loved the flight attendants and the desk staff everyone was so friendly and made me want to travel delta again."

Pros: "On time"
Cons: "Small aircraft"
Pros: "Staff, service, options"
Pros: "As usual great staff and awesome entertainment/connectivity"
Cons: "Due to weather & maintenance flight was delayed for IFR release & fuel temperature gauge issues. Staff was very helpful. Would have appreciated a drink voucher. Some unprofessional passengers took their frustrations out on the flight attendants."
Cons: "Over an hour delay before boarding due to supposedly bad weather. Because flight was overbooked they were offering $400 gift card to change to standby on another flight. If you didn’t make that flight (evening), you’d be confirmed on a flight the following morning with one stop in Detroit (we booked a nonstop to Chicago). Uh, no thanks. Then to top it off, we’ve landed and been told that it will be at least an hour before we can deplane due to no availability at the gate (it’s 1145 pm right now). All this plus their new policy of not allowing us to select our seats because we bought the cheapest tickets. Really Delta? You go ahead and cater to the rich and I’ll choose to fly with another airline."
Pros: "Crew friendly"
Cons: "Middle seat with no option for me to move"
Cons: "Break downs again... At least this time they found another plane."
Pros: "Flight attendants were pleasant."
Pros: "Friendly service, comfortable seat, on time, no issues."
Pros: "The crew was great"
Cons: "The flight was 4 hours delayed"
Pros: "I flew on a basic economy fare (I understand the restrictions) and was seated in Economy Comfort +, so that was appreciated."
Cons: "I could see on the Fly Delta app that I had been placed in seat 10B, but neither the app nor my boarding pass gave me a group to board with, so I assumed that I needed to board with group 3, which necessitated gate-checking my rollerboard bag. Only when I approached the gate to board did I notice on the info screen that I had been "upgraded" to Comfort + and granted boarding with the Sky Priority group. I wish this had been clearer so I could have avoided waiting to board and gate-checking my bag. Minor inconvenience but room for improvement on Delta's part."
Pros: "Friendly staff and comfortable seating"
Pros: "This was not my original transfer flight but everyone was much nicer and helpful than serious and being rude. Love Delta, I did not flight United because I wouldn’t have met my United flight once landing in ATL. The Young African American woman who was at the gate was amazing and so reassuring that I would make my flight to Chicago. Would book Delta, just because of how nice she was to me."
Pros: "i liked that staff and crew were very communicative and pleasant."
Cons: "one crew member didn't show up and caused delayed flight."
Pros: "Flight was on time. Boarded quickly with no fuss."
Pros: "Flt on time, very nice and friendly gate agent and flight attendant"
Cons: "Too tight and seats not comfortable."
Pros: "The Delta people were solicitous, efficient and brilliant the whole way through. We had not a bit of trouble. Our first class seats were comfortable, but with the supplied blanket, pillow and poor air conditioning it was a hot flight. The cabin personnel were wonderful as per usual, and my tasty gin and tonic soothed any discontent. I wish I could fly this way all the time!"
Cons: "The private contractor handling wheelchair assistance was terrible. A Delta employee theorized that they do not pay enough to attract and retain personnel. Our pre-arranged chair was not there, multiple calls by our Delta assistant finally got us a ride to the chair holding area, but after about 45 minutes we gave up and shuffled off to the security area on foot. Thank goodness my hubby is mobile enough for that to have been an option. When we abandoned our wait we were still 4th in line for an attendant to push the chair. If Delta has any responsibility in this it would be in the retention and compensation for the private contractor."
Cons: "The delta studio didn't work with Android 8"
Pros: "We were traveling with a toddler and infant but put in different row because the tickets were purchased separately. Gate staff promptly put us together and even bumped us up to delta comfort. Was a very pleasant trip. Thanks delta!"
Pros: "Plane arrived early"
Cons: "They board the front of the plane first, meaning the aisles get clogged up slowing down the process. Also, staff kept insisting pre boarding that more people needed to check their bags because there wasn't enough overhead bin space, but there were plenty of bins not full by take off."
Pros: "Accident on way to airport, so I showed up to check bags 45 minutes before flight time. They said they couldn't get the bag to the plane..in 45 minutes? So, they put on the next flight... 6 hours later. Said I could fly without the bag... uh, no thanks. They would not look for alternatives without charging me more. Flight attendants were crabby, otherwise everything was fine. I flew British Airways a few months ago. Night and day. Seriously. Delta does not even approach having good service. There was no comparison to British Air--- Delta is not in the same league."
Pros: "Airline stewards were very friendly and pleasant."
Cons: "We booked with Delta, but were put on Air France. Even though we had our boarding passes in hand we had to wait in long, slow line for baggage tags because they would not print from kiosk. There was minimal Air France staff on duty serving thousands of passengers during busy season (July). While the lines grew larger, the staff was reduced from 4 to 2. Another long, slow line for customs, another long slow line for security=Charles De Gaulle airport was awful. We arrived at the airport 4 hours before our departure time and got to our boarding gate with no time to spare."
Cons: "Very uncomfortable, seats did not recline and seats way too close together."
Pros: "Entertainment options weren't bad. Most of the crew was polite other than one flight attendant who seemed ambivalent and unhappy to be there."
Cons: "Three hour+ flight and just one tiny bag of pretzels? And no lemon or lime wedges on the beverage cart? Plus, I have to pay extra for one checked bag. I will only fly Delta if I have to in the future. Subpar airline."
Cons: "Free wifi"
Pros: "The plane ✈️ itself the attendants . The entertainment on board. Really great"
Cons: "Nothing dissatisfying about the flight nor the airline staff . Very polite, very professional. It was a Great flight. For long trips this airline is one of the best."

Pros: "Fast boarding"
Cons: "Slow in refuelling, got us delayed for 40-"
Cons: "Delay due to strike"

Cons: "Boarding was delayed and prolonged My Baggage was not transferred and was not available when I arrived in Dulles."

Pros: "The crew was great. The soecial meal request was hadled well despite oversight."

Cons: "Cabin was crowded. Leg room was scarce, short seating space. Almost no room for sleeping if you're not a frequent economy traveler."

Cons: "Flight was delayed 3 hours"
Cons: "wasn't able to take the flight since I missed it"

Pros: "The flight to Gdansk took off and arrived on-time and the staff were professional."
Cons: "The flight to Amsterdam from Gdansk was late and I had to RUN to the connecting gate. 50 minutes is NOT ENOUGH time to go through passport control."
Pros: "Comfort was better than on the previous Dash-8. Food was OK."
Cons: "Despised the cold temperature and cold draft in world business even with all vents shut off...gave me a head cold. Boarding was disorganized. There was no sense of direction; ergo, everyone was jumping in."

Cons: "Nothing.... I enjoyed every moment of the flight."
Pros: "Very friendly crew going out of way to assist in making trip comfortable"

Cons: "Flight departing late."
Pros: "On time"
Pros: "Good flights. Good prices."
Pros: "Flight crew; legroom even in cheap seats."
Cons: "Exceptionally unhelpful customer service when asking about extra kilos/bags. Just quoted the online info back at us. We simply wanted to know how much would be charged if the bag was 1-2kgs overweight. We could not get a straight answer, just quoted the unclear company policy. Extremely frustrating and annoying. KLM offer a superior flight experience - it is a shame their terrestrial customer servic does not match it!"
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"
Cons: "Service from airline host Poorly maintained plane Bad food Old entertainment"
Cons: "Flight was delayed 8 hours. Arriving at Incheon, discovered ground crew were unaware of our arrival to take this connecting flight. However, we were put up overnight in a hotel, which was nice."
Pros: "Usual professional and friendly service from my airline of choice for most destinations."
Pros: "Everything. Staff incredible."
Cons: "Our flight was canceled from Amsterdam to Bordeaux and did not receive any direction and had to find alternate flights for ourselves with the personal expense of using our own cell phones. Then our luggage lost for 3 days. Not happy!"
Pros: "Catering is ok"
Cons: "Seats comfort really old school"
Pros: "Crew service"
Cons: "Flight delayed."
Pros: "The staff were friendly and all smiles. Seats were comfortable and we had a quick, smooth flight from Edinburgh to Amsterdam. The breakfast supplied was an egg and mayonnaise sandwich plus a drink, which seemed about right and very Dutch in character."
Cons: "It was rainy and necessary to walk outside to access the plane; the staff should give their customers a heads-up so that jackets can be donned. Additionally, the check-in queue seemed rather sluggish."
Pros: "Quick (relatively) flight."
Cons: "Skinniest seat ever. Couldn't even lean back. I now have hunchback."
Pros: "Comfortable flight to Amsterdam for vacation in UK. More meals than expected. Also wasn't expecting some of the comforts offered to "regular" class seats like eye masks, ear plugs, pillows and blankets. It was an overnight flight, so maybe that should have been expected, but I don't think we had those 4 years ago when traveling overseas."
Cons: "Nothing. This is filler text to meet min characters."
Pros: "Short layover connecting from US flight and luggage transferred ok to destination. Food option not great but at least they didn't charge for it unlike some other airlines. No entertainment but to be expected on such a short flight."
Pros: "KLM fed a sandwich even though the flight was only 2 hours. The crew was pleasant. Getting through the Amsterdam airport to catch a connecting flight with only an hour to do so was no big deal. Airport staff was pleasant and helpful."
Cons: "Did not get the luggage from connecting flight from Amsterdan to Basel"
Pros: "Nice, turbulent-free flight. Food was good, service with a smile. Leg space was OK because Boeing 777s are usually better at this."
