I have no Comment. Super clean, Fantastic Crew, Food was delicious. Also wanted to add the Zurich Airport. Super nice people everything is in order super clean.

I like it very much it was a good experience with an excellent service

The boarding of this flight was total chaos. For some reason, all passengers had to stand in a lengthy line at the gate to have our passports checked for the FOURTH time. No reason was offered for the necessity of the fourth re-check, and when we got to the end of the line, the check was perfunctory. There was little to no crowd control at the gate and in some cases, tempers were flaring. On the other hand, once we got on board, everything about this flight from start to finish, especially the quality of the food and the service, was probably the best I have ever experienced..

The seat and leg room is small on the 2 seated row. Otherwise, very good crew and service.

The meal was wonderful and strawberry ice cream was a plus.

I haven't flown Swiss in a long time. I was disappointed that after paying $14,907 for 3 business class seats, we still had to pay another $200 for a single business class seat. All the window seats used to be single seats. Now it's every other one and if you want a single seat it's extra. Also, The double seats do not have pods or any privacy. We landed in Chicago after a long 10 hour flight and our connecting flight was on United. Because we do not have status on Swiss, we were not allowed to use the United lounge, even with business class seats. My father is on crutches and we had a 4 hour layover. No lounge was also disappointing. All of my status is on British Airways so I will go back to flying BA. We flew Swiss because my father did not want to go through Heathrow. On a positive, the crew were super nice and accommodating for my father who had recently had hip replacement surgery. Food was okay. I"m not a good person to critique the food, I never like airplane food.

-Swiss airlines online check in app crashed multiple times -Zurich airport does not have very many bathrooms accessible to people with disabilities - closest disability accessible bathroom to departure gate was 1/4 mile away.

Great food - movie selection was good. Plane was a few minutes late but got to destination on time.

It was great! Friendly crew. Good food and service. Great snacks. But one of our luggage did not come to Chicago. Stood at carrousel until the end waiting for our bag and it wasn’t there. Then we had to rush very fast to catch our connecting flight to Cleveland and almost missed it

The two meals were plentiful and excellent. The drinks were continuous. Thanks, Crew very polite; however a bit "hazard" at the end as they were rushing us off; to prepare for the cleaning team and next flight. Baggage from Berlin was delayed; however through the apps etc; they kept me aware and informed.(.did receive my baggage about 36 hours after my flight arrival). Good experience; thank you.

My daughter always gets sick when we order the gluten free meal option. Internet didn’t work as advertised.

The flight was very cold, and the seats were rather uncomfortable. The food has been better on our other SAS experiences. Most significantly, the luggage with most of my wife's personal items and clothes didn't make the flight. Hoping for a quick resolution, but no real opportunity to speak with a Human has us concerned.

It was so hot on the plane. No air jets above the seats

Very unfriendly approach to me when you rescheduled my return flight due to your delay. No help to address my health concerns because I am diabetics and had orthopedic problems. No clear explanation where to clear customs. I had poor customer service

Please see my comments for the flight from Chicago to Copenhagen

We were sitting in SAS plus. Super friendly, service that went above and beyond on a Full Flight too! Meals were deliscious and trays were cleared promptly. Generous drinks offered throughout the flight. Would like to suggest better movies on offer to watch.... In all genres and maybe more cooking shows? There was only 1, Nadia's Everyday Baking... Thank you

The meal offered was fish. I am allergic to fish. When I told her, she just took the box of food back without offering me an alternative.... I had to ask... can I then have a bag of chips? She did give it to me. I am a Euro Bonus gold member. Please just take the time to offer something else. Easy and from a customer service point of view, .... Considerate.

Different airports have different regulations (weight/size) for carry-on.

Check-in for SAS at Zurich Airport was absolutely horrendous. Mixed with 4 or 5 low-cost airlines at the same desk with only 2 desks open for bag drop initially with incredibly long lines. They constantly had to get people to the front of the line for flight that were departing soon. We just made it to the gate in time for boarding thanks to the efficient security check. Not up to the standard of the SAS pricing!

This was my first time flying SAS and used them for 4 flights. The crews, flight and communication was outstanding. I flew premium economy and was extremely impressed by their SAS lounges. I will 100% ise SAS again. Everyone was so pleasant!

Flight crew was super friendly and helpful. Food was frequent and honestly pretty good. Plenty of on-board entertainment. Economy seats are super cramped for such a long flight, but the crew allowed people to get up and stretch, and kids could wander with their parents, so we all made it work. Overall a very good experience.

I couldn’t make my first flight due to weather delays trapping us in the town we were in. Then I had to buy a new ticket

The seats were comfortable and we had leg room. Great entertainment.

I feel bad, but Swiss airlines is not an airlines I will ever fly again. Their cabins are basic, seats are extremely uncomfortable, crew is a hit or a miss with service. What's worse is how they make you feel they are there to make money and not make your travel needs be met or make your travel a pleasure. They charge for 2nd bags, seat selection and felt like a budget arinines frontier/spirit airline attitude and approach. Their business class is from the early 2000s, basic. Additionally, planes going to India, are old, falling apart and not maintained. Even the crew mentioned this is typical of the airline having older planes going to India. Panels detached and loose or stuck with duct tape, seats scruffed up and dirty, seatbelts roughed up. The scariest thing was when I saw a window panel next to where I was sitting loose and dangling. The crew mentioned it's only cosmetic and assured the integrity of the plane was inspected by the maintenance crew. This is where they confessed about planes going to India being old. I UNFORTUNATELY would NOT recommend Swiss airlines to anyone and will NEVER fly with them again!

Ability to watch movies.No earbud sound system.Marginal beverage service.Unexplained late take off resulting in VERY tight connection in LA which proved maximally stressful.

Sitting in 1A I can honestly say, that being a first class seat the leg room is sub par. The crew was attentive and friendly. Food was a a cheeseburger with fries. Fries on an airplane came as expected: no very crispy 😉

United Premium Plus or Premium Economy was almost twice the price as regular Economy, but the value is much worse. The seat is a bit wider and more comfortable. but not by much. The food was not good, felt like cheap fast foods on a little bit of silverware. The flight attendance service was the worse, not much attention to passenger, no helping of any kind. All in all, United Premium Plus is not worth its price, and was much worse than its Asian or Europe counter parts.

On long flights with semi-comfortable seats the airline needs to accommodate for the need to stand up. Otherwise a fight becomes pure torture. Not even business class provides for that.

The flight and staff was very good However: we could not check in using the website. We got the reminders and updated information but could not check in on either flight. And we did have the United App. Also just a tip for fellow travelers - going through customs in Chicago Ohare Airport it terrible.

I had always heard bad reviews about United Airlines so I have always avoided them when traveling. Little did I know that when I booked my flight with Swiss Air they would swap it to a United Airlines flight. The change was made only days before my departure leaving me no option to cancel or get a refund. I hoped for the best but experienced the worst. I paid for 2 seats for my daughter (13)and i to travel together. Both times leaving from home airport and returning from vacation, they sat us apart from each other: different seats and rows far away where we couldn'teven see or waive at each other. There was no option to change because by the time you're allowed to check-in the only seats available next to each other cost nearly $200 each. I stomached the extra cost from the first flight hoping the return flight would be better. No chance! The return flight was worse. I was sandwiched for an 9 hour flight between 2 stangers while my 13 year old sat 5 rows down . Just horrible experience. NEVER AGAIN will i fly Swiss Air or United Airlines ! So disappointing.
