Bags lost no more to say, bad communication and no urgency to get it back to the hotel by the airline properly the worst airline I have used.

Bags lost no more to say, bad communication and no urgency to get it back to the hotel by the airline properly the worst airline I have used.

The customer service rep on chat refused carrying golf set at no charge that is customary for LOT and others. I wanted yo carry just ONE club not even full set! Web check in was nightmare. Most horrible lounge at warsaw. To call it business class is a BIG exaggeration. Rude staff warsaw to nyc. Seats uncomfortable and not flat as is now customary. Bad content and entertainment system.

It was was okay but the seat was stiff and hard to sit on it!!

Seats were so uncomfortable, my butt hurts so much, I wish they have more cushions,it really was horrible, Except that, Stewarts were polite food was decent

The 737 lacked business-class seating. It was basically economy plus but with the middle seats left unsold. There were no TV screens but good food and service.

Everything was good, flight was smooth and on time Like service

Boarding was impossible to navigate. Had mobility issues and a business class ticket, but still boarded almost at the end of the queue because there was absolutely no organization or assistance.

Aircraft was new. Food so so, especially vegetarian was very disappointing.

Very courteous staff. Abnoxious passenger in front of me who reclined her seat all the way without warning and without considering the person behind her. My flight ORD-WAW was so much more pleasant because of the courtesy of the passenger in front of me.

LOT told me on my first flight that I had missed boarding my second flight and told us to go to a service desk to reschedule. We then were told our flight was still boarding and that we had to run through the Warsaw airport to catch it which is just a long long runway airport. The workers at the airport were not helpful at all and you have to go through two passport checkpoints. I have asthma and was almost dead when I got on the plane and no one helped or gave us water or even acknowledged us. The flight was fine - the crew members are not friendly so it’s a very functional flight at best. Also my bag didn’t make it to my final destination.

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.

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.

It was fine, definitely older planes with no charging or anything. There’s no entertainment set up on board, but it is nice that they allow you to access the in flight entertainment from your phone without having to pay for the Wi-Fi and they do offer free texting.

I liked that the flight was nonstop from ORD to CIU for $200 round trip.

All flight attendants could benefit by taking an international flight on Qantas Airline. Qantas attendants are much more hospitable in every way. Much superior than and attendants on any US airline.

While the staff was pleasant and helpful, the following observations are for your awareness. There was some delay on the tarmac on take off and landing. The paid lunch/food offerings were limited. Entertainment was only available on WiFi at a cost.

The first flight was better in terms of the aircraft.

So far so good but food and entertainment are not available for this flight

Smooth flight. Boarding was chaotic. Could not hear the gate agent over the intercom. People were lined up in the wrong lines. Groups one and two were told to board through line one and group 3 through line 2. All very confusing. Once in the air, the flight was smooth. There was no entertainment option on this aircraft, even though it was a larger aircraft.

Overall poor for me I paid extra for seats with leg room and my regional flights exit row seats have less leg room then the others that's money that could have been saved and on my final flight home the flights air was not operating it was unbearably hot in the cabin I will be contacting United and filing a DOT complaint

It was my first time with United Airlines and I would say it was very good experience and best of all the flights were on time. Will definitely fly with United Airlines next time.

Very modern plane. Good seat spacing. Meals were good. Screens had tons of movies and worked

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
