Flight was on time. Could have been a little more comfortable. Baby cried all night.

Flight was on time. Could have been a little more comfortable. Baby cried all night.

The chicken on the flight Boston to Zurich wasn’t very good. It was bland passable. Too much sugar in the Cole slaw. Cabbage is an amazing veg and can be much more crisp and alive. Flight attendants were Wonderful! Seats were a bit beat up but okay. In economy it was tight when the person in front learned back the screen became too close.

On time and my bag made it. My parents on British Air had their bag held/lost at LHR, so Swiss definitely won that contest.

Wonderful, i asked at front gate to change my seat up closer and they gave me a row with no one in it. Very kind of them as the flight was on the light side.

Great crew, great food, horrible aircraft seat spacing for a 9 hr flight.

The food could have been better but everything else was superb.

Horrible!! The WiFi was not working, the food was awful

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

Excellent Airline. Food, crew and comfort was perfect. Entertainment screens were old. Didn’t like them.

Crew members were good. Seats were packed and too tight .

Flight crew was very kind and polite. They had to deal with an unnamed issue right beside me, and did so with respect.

Good flight. Mass boarding. Seats fairly comfortable. Food okay although may have upset my stomach a bit.

The crew were nice and courteous. Exonomy seats were worse than expected. Overhead bin space was non existent thanks to loose enforcement of the carryon size and letting passengers put up their purses jackets and backpacks up there leaving no space for others with a small conforming carry on. Food was not good at all. Perhaps worse chicken I ever had in my life. I had to have them take it after tasting how bad it was. Whoever made that should not be in food making business.

The crew was very helpful and friendly. Food was good. The only issue was the legroom -- not great. The seat in front is also too close to see the entertainment screen properly.

No crying babies the whole flight would be nice. Impossible to sleep. No free snacks , only the main meal

The crew was amazing. Our seats was not very clean and even that was not a full flight but our seats was right beside the WC which did not let us to have a moment of rest.

Excellent service, and came on time! Thank you for your dinner that was chicken with salat/, and 🍰 it was good quality food , the breakfast was very good with good cheese , butter,etc and the tea was very good quality. The space where I was seat was nice so I could stretch my legs. I dit not have the bread as I am in a keto died. Have great time everyone in Scandinavia airline.

The stewardess was incredibly rude. The gave you only one drink with dinner.

Crew was unresponsive to request for a soda. Food was horrible and I’d venture to guess many others thought so as well by the amount that they trashed. Made me sick to my stomach and ended up in bed the remainder of the day once we arrived. Screaming child for 3/4 of the almost 8 hour flight. Crew had no headphones whatsoever for free or purchase. Seating way too tight and we upgraded our seats. I do not see us ever flying this airline again.

Boarding and crew were excellent. Seat could have been more comfortable (hard on lower back).

Boarding was 2 hours late and then we were delayed another 5 hours on the tarmac. I'm sure the crew were also tired, but some of them were rather snappy. The special dinner I ordered was not served, and they only served a tapas box on takeoff and breakfast before landing. That was disappointing in premium economy. However United was good at rebooking my connecting flight.

It was pretty good, they give a small blanket, neck pillow and earphones. The only bad thing was not big enough leg room for your bag and feet. They gave us a snack, dinner, and breakfast on flight and food was good considering it was on a plane

The crew was great. The food was typical, but decent. Everything else - mediocre to poor. The flight was late arriving - happily for us and our 49 minute connection (what idiot came up with that?)- in another concourse - that concourse changed before we arrived (ticket and app was showing the incorrect gate - when we boarded at the correct gate - known by the airport person pushing my assistance cart). Had I walked and read the screens or United app I would have missed the flight! May other people arrived late to the correct gate, having been victims of a last minute gate change, were also relieved the flight arrived late. The aircraft (Boeing 757) was a sardine-can due to an uncomfortable seat pitch distance. The material or seat was beyond not comfortable, but I'm sure they made a lot of money with that aircraft type. I spent a lot of time standing in the back (in the middle of the night/morning to rest my back). I learned my lesson - any trans-oceanic fight - avoid United or American Airlines - and look for Airbus or Boeing 737, 767, 777. Also, pay for business class or premium coach seating.

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

A little more friendliness from that crew of the day.

Staff didn't seem confident about the ingredients in my lactose intolerance meal

the seat has a problem. the back had a hole.

My flight was delayed so bad i missed u it so i just said never mind

Delayed 2 hours while stuck on the aircraft. If the luggage was properly loaded the first time we probably wouldn’t have been delayed at all

1. Everything was satisfactory concerning the flight. 2. Can't think of what could be better right now.

Was hard to sleep, but other then that everything was good.

We got to the runway and had to go back to terminal to have plane worked on, which is fine, but the 40 minute connecting flight was already gone because of this delay and had to wait 5 hours to get on a different flight and only got a meal voucher which I didn’t see the email until after I had already ordered and paid for food. I feel I should be compensated.

I paid for our seats and when we boarded and went to our seats it was the last row. I would have never paid for my seats knowing I’m sitting in the last row. The airline must have moved our seats and I didn’t realize it when we checked in.

Iceland air transfer was bad. They lost my luggage and I just received it 11/1

Handling our luggage was the biggest issue - they lost it and we got it almost 3 days later. Really threw off the beginning of our trip and we really had to change our itinerary accordingly.

The flight was delayed and as a consequence we missed our connecting flight. Were stuck for another 6h in Reykyavik. Appreciated that we got a generous food voucher at least. Would have liked to see more information upon arrival including a person waiting for connecting flight travellers and informing already that we will not catch the flight and directing us to the office dealing with the matter; unfortunately that didnt happen and we hence first needed to find out whether flight had indeed left already and then locate the adequate office to help us with booking us on the next connecting flight. Also my suitcase broke and it is not clear whether it is happened on the leg with Iceland Air from DC to Reykyavik or on the leg with Lufthansa from Reykyavik to Frankfurt. Finally, understood that it is a low cost company but at least provision of earplugs for free would have been nice, instead of making them buy.

Had a screaming child next to us. Not the airline’s fault but still annoying.

Seats are way too much now with these new airplanes especially long flights like we had. I was 7 month pregnant and in a lot of discomfort due to small seats.

My biggest problem was the flight from KEF to DUB was delayed, which caused me to miss my connecting flight in DUB and we were forced into an unplanned 10-hour layover in DUB. Crew and boarding staff were all very friendly but this was a real inconvenience and especially uncomfortable for my disabled wife.

The seat size was more like a domestic than an international flight. In fact, i would compare the ammenities, quality and service to a short hall ryan air flight, which was unexpected for an international flight. The plane was extremely hot so sleeping was difficult. My biggest complaint was that they are very strict on carry on luggage only allowing it to weigh 10kg/22lb. I try to limit myself to a carryon so i don't have to mess with bagage claim, but the wieght restriction made it impossible. I have never had a carry on weight restriction (at least enforced) on an international flight. Will not be including them in future searches.

When our flight was canceled and rebooked, my husband's meal request was not transfered. As a result, there was nothing he could eat for dinner and breakfast on the new flight, save a side salad and roll.

Very efficient and excellent service. Nice amenities and beautiful plane. Elevated meals. Boarding could have been more organized. We missed our connecting flight due to EU entry but Lufthansa was extremely quick to rebook us.

Missed it by a couple minutes and couldn’t find an alternative flight so had to spend the night in DC and after much shuffling from 1 airline to another managed to get a United to Frankfurt.

There were only 2 toilets and one of them did not work in business class. We are not allowed to cross classes so had to wait in line to use the toilets!! The entertainment touch display was finicky and did not work all the time.

The flight and crew were good. The customer experience on the ground could have been better. We had to reschedule our flight because of a delay on the previous flight. The attendants working the desk in Washington DC were not helpful. They told us to scan a QR code and that would get us rebooked. Why couldn't two people standing at their computers do this? We had to chat with someone to get everything figured out. It was extremely confusing.

good entertainment package but rather small seats for business class

The male attendant has zero personality. It seemed like he was over worked or hated his job, not once did he smile or made any contact with the people on the plane. Strictly business and call it a day!

Our flight was delayed for over an hour due to weather, and it had already been a long travel day. However, the crew was calm and compassionate, listening to every complaint with genuine concern. They got us home safely without incident, in spite of all of the obstacles. I’m grateful.

Bad! Disaster!! The LH419 was cancelled after 4 hrs on board with no AC and no toilets

We had almost a 6 hr delay, primarily due to weather, the e problem was that they communicated this delay and its length very poorly. The boarding was chaotic - even though they had hours to figure it out! The plane was an old 747 whose touch screens barely worked and there was a faulty USB port under my seat rest (something that wasn't labeled as being there) They organized my delayed luggage well. And I could get updates on the Lufthansa website. My shirt connecting flight charged for everything except water. Coffee was over 3€
