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

Swiss airline do not allow online check-in before 24 hrs, this is very inconvenient to us. I tried many ways such as booking code(6 numbers) or 13 booking numbers , neither of them work, Lufthansa is better which allow us to check in even before 30 hrs, so we can assign our seats( not many people want spend extra money to assign seats on top of airfare which is already spent.)

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.

We are glinting with united , but over all very disappointed

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.

They lost my luggage and despite all follow ups through emails and phone calls they don’t give me an update

Service was courteous and attentive. Sat in the exit row. In exchange for leg room I had people tripping over my feet to use it at a hallway from one aisle to the other, had no access to films viaa viewscreen and no underseat storage for medicines or other personal travel needs. Next time I am seated there, I will refuse the exit row.

Crew and service was excellent. My seat was super small and cramped! No leg room
