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

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...

When I needed to get my bag off of the plane so that I could take a train because the connection was 4 hours later, they took 2 hours to take my bag off making me take the train and miss my flight simultaneously. The seat size on the plane is too small for an average aged woman let alone a middle-aged man. It's unacceptable and I will not fly Boeing again.

The cushion of the seats are old and very thin. The food can be more tasty or come with salt packages

The biggest let down was with booking experience through Kayak. I booked a flight with checked bags on Kayak. Right away I got a message from travel agency that the flight is not confirmed and to call them. I called them and they said the flight I have booked is no longer available with the price I have booked it for and I can book it with about $100 more. I already had other options I could book with cheaper price so I asked them to cancel my booking. Then they said I can have the ticket with the same price but a date change which was not working for me as I had to be there for a seminar. So again I said no then they said they will cover the charges and confirm my flight. When comes time for check-in I see I have no checked bag option which means the travel agency deceived me saying I can have my booking as I had booked it. And at that point I ended up paying $155 for my checked bag going back and forth. I am extremely angry and unhappy with this experience

PLEASE DONT TAKE FORCEFULLY(SIZE APPROPRIATE) CARRY ONS FROM PASSENGERS WHO FOR SOME REASON NEED TO KEEP IT

It was great. My seat was comfortable. The bathrooms were clean . The service was superb . I travel a lot and I have been in 64 counties. I wish I could fly first class, even though I could , but I prefer to budget my yearly travelling expense on actual visiting , not on flight. Anyway, my point is that your economy was far much better than other airlines as good as Air France. The flight attendants and all crew were polite and very helpful and respectful. Thank you for making my long trip tolerable.

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.

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.

Impressed with the service despite turbulence because of the weather. Both flights arrived before their scheduled times.

Great experience…left a bit behind schedule but made up fir that in the air and landed 10 minutes early 😁

The seat and leg room was not good. The food and beverage service was good.

For economy, it was very good. Staff was great, they even let some of us change seats for more leg room... Put an empty seat between us which was fantastic for a 12hr flight. Onboard entertainment was excellent, I think over 200 choices of movies/tv/etc The bad was the barely/nonfunctional wifi that cost either $16.99 or 1700 miles (full flight). It was atrocious... Definitely the worst of the last 3 long haul major airlines I was on the last few months.

Electric plugs didn't work. Entertainment system wasn't working

The design of the light switch on the arm rest is ridiculous.

The gate attendant let me walk right by her with a bag too big for the overhead compartment

Overall, it was a good experience. Boarding was good and there was plenty of overhead bin space for everyone’s carryons (even when we boarded toward the end). Only improvement would be to offer trash service more regularly.

David went above and beyond to make our flight the best that it could be

No food service almost missed because of first flight delays

I’ve been traveling for 20 years. I tried Turkish airline for the first time horrible horrible service and it would be my last time even if I get offer for a free ticket, I will not accept it. They have races and the worst Flight attendant

It wasn't good. I didn’t understand. They changed 320 dollars for 2 luggage. My ticket was regular and I paid almost 1200.00 dollars. Why they did charge? I want my money back.. thanks Yılmaz polat

Very punctual, the onboard staff was friendly and correct, the flight was fortunately very calm, the toilets were clean, in short, an excellent experience Thanks

Ordered Vegan meal - it was ok, but not exceptional. Seat ok row 39 middle section aisle. Nearly full flight - crew was busy but they did the best they could. There was a USB A port at the seat. I listened to my own music and only looked at flight information. One nice thing was the connection information was made available in the screen.

Very nice and friendly crew. Boarding system can be improved.

The Etickets had been changed (Why?) without notice ; Hence, that caused troubles when checking in. Not until I contacted my ticket agent and was given correct Etickets could I then check in.

Cleanliness of seats, trays, storage pockets need more attention, but everything else was good.

A great airline, no complaints at all. My experience with Cheap Tickets was very disappointing however. Two hours after purchasing the flight they called to tell me that the ticket price had gone up. I’ve never heard of such a thing. That is called false advertising; I will never use this ticketing service again and will warn all friends to never use it.

One of the worst check in process at the DIA as well as the boarding counter Changed seat at the last minute and assigned middle seat while I paid for window seat. Requested many times but to no avail . horrible customer service and very poor process Requesting refund for seat that was changed last minute

Good overall flight. Excellent crew. Food options could be improved.

Flight was delayed but the real issue is how long we sat after boarding. Space very limited for an overnight flight and seatbacks didn’t recline so it was almost impossible to sleep.

The staff made sure I was comfortable, moved me to a better seat with more leg room

Easy boarding and comfortable seating were plusses. Enjoyed the experience and good service from the captain and crew. Many thanks...!

Somehow, my booking was under my preferred name instead of my legal name so they almost didn’t let me board the plane at LAX. This problem should have been notified to me when I was still in Toronto.

Great overall. Quick boarding, attentive staff - great experience in premium class.

When arriving over 2 hours early to check k in at Charlotte airport I was told I would have to check my carry on ? Apparently the flight was full and may not be room. I was not given a choice and the agent was quite unpleasant about it. I am a senior amd was not comfortable me having to worry about my bag being lost vut it didn’t seem to bother him. There were lots and lots of people of all ages in line when we boarded with carryons and most larger than mine .the rest of my journey was pleasant vut this was totally unacceptable.

The layover was 6 PLUS hours and we were only given a $15.00 voucher. We missed our first activity in Quebec due to the delay.

Miserable staff as it was a late/delayed flight and crew wasn’t in the best spirits. Completely understood as neither was most of the passengers. Still unacceptable l.

Or the greatest and it ended up picking us up from Chicago to Toronto not sure who was tesponsible for the 4 hr delay. United should have been properly prepared for a scheduled flight from Austin to Chicago and they were not.

It was a short flight, and no entertainment. That was not a problem for us, but there is no option for "not applicable". There was a bit of turbulence, so there was no food service.

Flight was 1.5 hours late to depart so changed flights to Swiss Air.

The United Airlines crew that operated this flight was subpar. They didn’t

Very small and uncomfortable seats, Hard to hear entertainment system sound. Horrible food. Staff doesn't care much about the passengers. 2nd time they didn't give me my vegetarian meal. They asked me regular food with meat. The airline and staff was from United airlines.

Checkin took along timen only.few angents available at.checkin desk. Customer support over phone no existence

At baggage claim, I was given the wrong printed ticket. The ticket belonged to another passenger for a different flight — to Zurich instead of Frankfurt (layover). I was even allowed to pass security, and when I asked the Lufthansa employee if I was on the correct flight, and why it was changed. The employee said everything was correct and I should board. When I got on the plane, there was someone in my seat, and the crew on the plane finally realized that I was on the wrong plane. When I got off the plane, nobody was willing to help, and the security refused to provide my original printed ticket. That was until I showed them that I took a photo of the ticket; once they realized I had photographic evidence, they were suddenly ready to help me. The Lufthansa employee began communicating with other airlines and found a flight that would take me to my destination via Polish Airlines. I was required to once again go through security, re-check my bag, and once again pay for my checked bag and weight overage fees. This experience was incredibly stressful and very frustrating, as you can imagine. A Lufthansa employee told me I would be eligible for a refund. Please tell me what steps I need to take in order to make that happen. Thank you!

The row of seats were so cramped it was difficult to get in and out of your seat. I even upgraded. A long flight and sad accommodations 😵‍💫 the shorter flight was very comfortable and the seating was spacious

I bought a ticket and paid for for our luggage but I had to pay for my luggage again. I’m so disappointed! We had a 30 min delay and because of that we missed our connecting flight and were told that we would be on the next flight (9am flight ) but we were landed we were booked at 12pm flight. I had a little baby w me, it was very stressful. I begged to leave at 10 am at least. I was emailed that we get a voucher but they didn’t work when we were at a breakfast store. I’ve been always happy w Lufthansa but this time was awful.

Good service … bus transfer upon arrival from plane to terminal: atrocious!!!

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

We had a 1 1/2 hour delay before we left Denver. When we arrive to Frankfort, they didn’t announce that people with connecting flights to exit the plane first. My next flight was already boarding when we we taxiing in to the gate. I waited another 10 minutes to get off the plane. I had to run to catch my next flight. I mean run! I made it with one minute to spare, but my luggage did not. My luggage came two hours later on a different flight.
