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

Absolutely amazing! Best airline i have flown with, huge difference to United!

All the flight to USA were arranged to E terminal whereas from Dubrovnik arriving on Zurich is on A80, have to walk all the way from A to E, even need transfer bus , for short transfer time like in an hour, we have to work fast, as soon as arrived at E, it is about time to boarding, pretty tight schedule, I hope Zurich airport can make some rearrangement so that transfer people do not have to walk long way. For short transfer time people, such as 50 min, this is even impossible if still like this.

...as stated previously, red tape should be shorted by Swiss in terms of generating refunds...

Delayed 30 mins Forced to check in my carry on luggage

The staff were nice people, the food was very cheap, one of the meal was a sandwich or nothing, I couldn't buy any food, mind expensive duty free WAS available right away. 🤒

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.

We are glinting with united , but over all very disappointed

second leg was more comfortable. Customer service in Abu Dhabi is okay.

Certainly! Here’s a more concise and refined version of your report, maintaining a polished and professional tone: --- Crew Check-In – Kolkata (CCU) The crew handling check-in in Kolkata was outstanding—efficient, courteous, and highly organized. Flight Segment – CCU to Abu Dhabi (AUH) A standard flight overall. Notably, only one in-flight meal option—a vegetarian curry—was available, which seemed unsuitable for a red-eye journey. The crew offered no alternatives, which was unexpected. Flight Segment – Abu Dhabi to Rome (AUH-FCO) Comfort improved on this leg, but service quality was average, falling short of Etihad’s premium standards. Crew attention was heavily absorbed by a difficult couple in Row 15 (port side), resulting in disproportionate focus. It was concerning that a steward had to personally return to apologize, a task better suited for supervisory staff. This highlights a development opportunity for supervisors Anna and Quashim in managing guest escalation professionally.

Horrible. After paying for seats, I was cramped, my daughters legs kept hitting the seat in front, I had no overhead bin space and no help from stewards on board, the food was served cold, when asked for snacks was told to wait and never received any, the flight was cold with no temperature controls. Entertainment was outdated. I booked this through partnership with American Airlines but will avoid in the future.

Horrible. After paying for my seats, I was cramped, had no overhead bin space, freezing as the flight had no temperature controls, the food was awful and served cold, when asked for snacks was told to wait and then never received any. I booked this flight as a partner through American Airlines but will avoid in the future.

Took a long time for boarding. The flight was comfortable.

Flight was delayed due to slow boarding process by etihad. Update food options and movies as well.

Should have had business class line in immigration. Food quality suboptimal

Used to Etihad employees are very rude and unprofessional but now better than before over all is okay now

Boarding was efficient, had to check in cabin luggage. Seats were narrow, food was more in quantity, received cabin luggage on the luggage belt which was fine.

Etihad flight sector is a local . .give the same quality upto destination

The crew was the best I’ve ever encountered. Business class was spacious, immaculate, and very modern.

I wish seats were not reclinable. It's so claustrophobic when the person in front of you spends most of a nine hour flight leaned all the way back. The crew was really nice though and the dinner (red Thai curry) was pretty compelling.

Our flights were severely delayed, then canceled and we had to fly out next day with no sleep accommodation help. This led to our baggage being lost and the service reps after baggage couldn’t be bothered to help. They kept sending us to different counters when we were at the right counter to begin with. The only saving grace was the angel woman supervisor with blond hair who helped us put in a missing baggage claim.

The boarding system was all bogus - employees at the boarding gate were not sound like proffesional or may be possibly rational

I got an email in the morning of the flight 1/7, from Kayak, that I was rebooked from UA 906 to LH 430. Nobody at Lufthansa ot United knew about this. I went to both counters. at the airport. Also, Cheap Flights, who I booked the ticket through, did not know. I ended up staying on the United flight. But this was very disturbing, since I got a very late notice that I was rebooked to an earlier flight, I hurried to the airport to find out after a lot of inquiring that this was a mistake. Not a good Kayak experience.

After living in Europe for five years and flying with Lufthansa and KLM airlines, I’ve realized that United Airlines is now a budget carrier. The flight attendant are not friendly. The seats are not comfortable. And everything comes at a cost. I will be flying with KLM and Skyteam like Delta to the US going forward no doubt. United Airlines is not what it once was:

Delayed take off but I think they waited for passengers.

I had to fly United where the flight crew was atrocious

Flight was delayed for no reason and I missed my connection. This added another day of travel and I missed an event I was traveling home for.

I traveled with my sister, however ,we booked a flight separately, and we don't sitting next to each other. The staff on the board where on the top of this unit they find us sitting together. Ty lufthansa team. U are the best

Better synchronizing the boarding processes. The audio announcements, the personnel and the digital signage were not saying the same thing. All confusion.

The first class seats were unusable, mine at the end of the flight, my husband's in the middle of the flight, and the one next to me was unusable either, they had to move the person to another seat.

Last minute gate change. Didn’t put our TSA global on our trip even though we asked multiple times to confirm. Did not help with food when could not eat what was served.

Our luggage didn’t arrive with us, that puts a damper on the whole trip.

The cabin was bit colder than I like but the crew members looked after us very well. They did even offer hot water bottle and hot chocolate. I cannot rate the crew enough excellent is not good enough. They really were wonderful.

Boarding is always a challenge as folks in al groups crowd around for no reason, but crew handled it well. I once again applaud the LHR ground baggage staff as they got our bags from a flight at Terminal 5A to a flight in Terminal 5C within 40 minutes...amazing!

This flight from London to Chicago was actually on an AA airline. I did book through BA but the flight was AA. Great flight, hectic in Chicago, I wouldn't choose to fly through Chicago again, but that's not the airlines fault. The flight itself was great.

Push back is not working when I complaint a male staff he told me that most of the seats are like that so we can’t do anything

Seats were way too small. I got claustrophobic waiting for trash from meal to be taken away. I couldn't move to even close my tray until trash was taken.

Was 3 hrs delayed and my poor friend I met in Barcelona was waiting at airport for 3 hrs. Dallas airport was awful

Why should I rate entertainment if I’ve not used? You don’t have NA - Not Applicable option.

Food is good, staff is good... Wi-fi quality is poor, disembarkment after landing is atrocious.

Flight crew was lovely. Bathrooms should have been cleaner. The handsets in business class for watching the entertainment are horrible. Very difficult to figure out which buttons are for what. I managed to get the flight maps on my screen but it wasn't easy. Never got anything else up.

Uneventful trip. Good flight crew. Food could have been better and a bit more of it. Cabin cleanliness was ok.

Inflight Services are poor compared to other airlines. They do not offer even water during 15 hr flight. Food is little in portion and I had food poisoning after last meal ( rajma chawal)

Boarding at Mumbai airport was terrible, the staff had no idea how to handle it. It was chaos - and led to a delay

My seats that I paid for were changed last minute and I had to sit in uncomfortable chairs

This was a bery good experience as it was a newer plane . AI older plane bussiness class is bad .

What a pathetic plane it was. Entertainment system didn’t work. USB port was broken. There was a hole on top of folding serving table. Broken restrooms in the middle of flight.

Our seat monitor did not Not work either way going to Vietnam. I had a bulkhead seat with plenty of room, but with No monitor, it was a long flight with no movies. Fun was good, staff was Excellent.
