I slept the whole flight so I can't tell you about the food and there was no entertainment offered. Crew was very nice, seats were comfortable in business, and boarding was easy.

I slept the whole flight so I can't tell you about the food and there was no entertainment offered. Crew was very nice, seats were comfortable in business, and boarding was easy.

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.

The service was flawless. The trip went great. I flew from Venice, Italy to Tampa, Florida. The issue is my bag (that I checked for free when checking into the flight) was ripped along the side when I collected it from baggage claim in Tampa, last night. I thought of talking with the Tampa baggage claim employees about it and see what could be done, but my bag isn’t a very expensive bag and I didn’t want to make a big deal of it. I’m not sure if I’ll be checking a bag anymore in the future.

I took this flight to be able to fly with Swiss instead of Air Canada from Geneva.. The AC planes have a better outfit in Business class than Swiss, but the service aboard Swiss is really best, first-class, as is the food and beverages. Though using the same plane model (A330-300), the interior setup of the cabin starts to show its age, but IMO the planes are better serviced by Swiss than AC. I had in my recent trips with AC way too many technical problems that led to delays or even complete cancellation of my flight.. Their fleet is aging (average 20+ years) and the maintenance has taken a toll compared to years ago. Cutting costs in every corner has to be paid sometime by someone, and it's the travelers at the end that pays for it. Unfortunately for me, flying directly to Zurich puts a much longer after-fly trip on me than Geneva.. so I might go back to direct flight YUL-GVA, even if I don't like flying with AC.

We are glinting with united , but over all very disappointed

We are flying with Swiss for a long time but this time was terrible do to are flight cancellations we are in some bad hotel with out normal food

It is a good airlines, very professional very good food. I wish they offered free luggage is the only thing.

better announcing at the gate prior to boarding and better organization of various gps

Flight attendant served beverage to everyone during meal service and forgot about me. Had to call her several times until she realized it. Not a good service for a business class flight

A bit rush for transit. Food and entertainment are not available

The gate was too far away for the connecting flight

Generally good. The aisles have gotten narrower which can slow down boarding. Flight crew was great! Healthier complimentary snacks would be appreciated. Due to earthquake in San Francisco we had to circle in air space for a bit but then had a smooth landing. I laud the flight crew for their patience ;)

headphone jack didnt work for the first flight and not much variety

The agents was very rude and they charged me $50 for a carry-on bag saying that it was too big and then I saw someone going on a plane with the same size bag as me

For the most part united was a good experience, how ever when they came by with the snacks and water, they completely passed by my wife and I. As we were in separate rows. On a 5 hr flight we were not offered water

Fantastic crew. Flight was delayed at last minute but we were given updates every 20 minutes and the crew was so friendly and considerate. I miss the touch screens on the back of the seats, wish they would bring that back though.

Beijing PEK to SFO. I had an economy seat on this flight. The seat comfort was acceptable. My main complaint is with the FA’s lack of personality and absence from servicing the plane, specifically restroom care (I wish I could share a pic of the restroom that I captured) and care of travelers—drink cart/availability of drinks. I'm amazed at the level of service on other International travel where a passenger is most often appreciated.

Awful. Worst airline I have ever been on. Crew were among the rudest people I have ever dealt with. United staff members were rude and disrespectful. My flight was delayed, causing me to miss a connecting flight. I understand things happen, but when staff start lying about what actually happened, that is when I have an issue. Just be honest, really it isn’t that hard. I’m being very honest with this review and I don’t find this difficult what so ever. In fact, because of United Airlines, my Christmas holiday was off to a really rocky start. As someone who has traveled across the world, it has only been United that I have had a truly awful experience.

Good flight. On time. Boarding and seating was easy. Crew were really friendly, yet professional. Bathroom (by cockpit) was small but serviceable. Some the seats were showing some notable wear & tear, but were comfy. Very happy UA customer. TY! 🤛🏽💗

I don't like anything in this flight the food was bad the service was bad the flight was old and not connected to the screen no intertainments at all and it was long trip was bad intertainments the crew not helping

The company tries shamelessly to squeeze every dollar)Euro out of its passengers. During the check-in the force you to go through the seat selection, you can skip it. They will assign you the worst seat available, then show you the other available seats on the map, for a fee. But they won't show you the fee until you click on it. And once you do click, there's no way to unselect it!! You will get stuck and forced to pay for that seat. Cheaters!!

The flight was great. I don’t know about the food because I was asleep and they didn’t leave me any.

The flight was great, smooth and even a little ahead of time.

There wasn't a time for neither food morning entertainment in a short one hour hop over.

Not online or self check in, sent emails in Italian language ,not recommended.

Premium Economy was average for class. Seat comfort was just okay. Crew was attentive. Checkin was fine and moved quickly. Boarding process in Rome was not well organized.

It was horrible the woman next to me was sick and I asked if they would change my seat and they said that they didn’t have any available. I sat next to this women for 9 hour and now I am sick .

We booked and purchase our seats in February for a September flight. We choose seats then also, did the online check in on the app the day before and all was fine. At the airline check in they charged our seats and we were not even sitting together after paying for business class seats. They separated us with no explanation and would not change them back. I was very upset. On the return flight, they tried to put us on standby! When again, we purchased seats in February for this flight. The plane was old and smaller and the business class seats were not comfortable like the flight from NYC. Flight attendants were hard to find once the first meal was served, luckily the flights were smooth.

Crew was good. Very nice staff. Wine was good. Problems- no AC while waiting for takeoff. Long wait so we should have been more comfortable. No water for quite awhile. Food should have been better for an Italian airline. Chicken was pressed rounds of processed meat- not tasty. We had only one hour for our connection- ran through airport- plane waited for us and staff was helpful.

The plane was very clean. The bathroom was clean as well. The land crew were very polite and informative and helpful. They informed me that there is a long way and challenging to go from international terminal to national terminal and in addition to getting my suitcases and going through customs and dropping them again for my second leg of trip which was San Francisco to Los Angeles . I have left knee issue and had a recent fall with aching muscles all over, the land crew suggested wheelchair help for me, God bless her. If I did not have help, I could not make it to my last terminal. Thank you UNITED AIRLINE!

I like the service and the efficiency. I am lactose intolerant and the lactose intolerant meal in business class was not astounding. Also, the business class fully reclining seats are not that comfortable.

Food was great but they didn't clear my meal tray for 3 hours. You'd think they could check though the cabin now and then.

Upon arriving at IAH, it was informed that the luggage had not arrived. Still waiting to hear back when it will be delivered.

I wasn’t allowed to board with my children. I was charged outrageous costs for basic carry on size luggage. The entertainment screens were outdated and not user friendly.

I was very happy with everything, thank you for the smooth flight ✈️

helpful and friendly. The Lufthanza people I dealt with before my holiday were so unhelpful by comparison.

I enjoyed my flight back with Lufthansa because the food was good, and the flight attendants were nice and helped you when you asked a question. The flight attendants always came around and asked if you needed anything which I liked a lot.

Entertainment system is old. Food can be tastier Need to provide toothbrush and toothpaste at least when asked.

The flight was cancelled due to tech problem with the plane
