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

Terrible airline both Swiss and Lufthansa that are part of the same corp. stay away if you can

3hr delay and then missed connecting flight with another 6hr wait at the airport before getting a continuation to my trip, worst trip ever in my 50+years of flight travel

Without a doubt, my “customer service” experience with SWISS was the worst of my life. Multiple disconnections in conversations, very cold and indifferent staff, failure to follow up with promised status updates — simply put, T. H. E. W. O. R. S. T. A full week later, and I am STILL waiting to hear from them. Never again for me with SWISS. Disgraceful.

The flight and all amenities were good to excellent. SWISS was awful to deal with. Every step of the way they nickel and dime you. Chose your seats? $14. Change your seats… No accounting for the prior payment. You get billed again. 17 pound restriction on overhead luggage, nonsense. It’s a weight in the plane whether it’s in the overhead or in check baggage. They just milk you for every cent they can and I resent it. The flight was excellent.

plenty of legspace, snacks, no pull face from flight attendants when asking for a wine. Also fast transfer ability at ZRH.

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 .

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.

You cancelled my flight and didn't arrange another. Sent no info except YOUR FLIGHT HAS BEEN CANCELLED. HERES WHAT TO DO NEXT. and the rest of the email was blank???

The first flight was delayed. We missed the second flight, which was rebooked 9 hours later. We missed all our arrangements for the first day of vacation.

Old plane, food not that great - lacked taste. Crew was nice but strict.

Terrible airlines, kept lying to me about the fact that my connection flight was cancelled. Left me hanging until last min. NEVER AGAIN

Mediocre. Maybe due to Economy light. Staff was great. Space shrunk, not for me, and definitely not for Vikings. Food was decent. Assistance lagging. There was a possibility to upgrade to Premium economy, however my bid was immediately classified as low and not even considered (though well over minimum bid). Thus I was no bleeding dry.

Upon departing and landing, the man seating in front of me had his seat leaning back. Taking off nobody told him anything. Landing someone from the crew said something but the passenger ignored him and nobody followed up. Felt a bit unsecured. If this that is some of the basics are missed, what else was overlooked?

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).

We were forced to eat vegetarian food because non veg food ran out. The breakfast was mediocre.

We sat on the hot plane for ours with very conflicting messages. Some (most?) of this may be due to the flight control staff, but we were also repeatedly getting "we are leaving"/"we are not" messages. It was very uncomfortable

Staff could’ve been a little more cordial. The men were much more friendlier than the women. My daughter and I also missed the 2nd to last meal as we were sleeping but that is on us.

Lost of requested seat assignments. Lost my husband's meal choice

Flight was delayed from 35 minute delayed aircraft arrival to 90 minute delay causing us to miss international connecting flight on SWISS resulting in 16 hour delay to reach detonation causing significant angst, monetary loss and discomfort. SWISS transfer desk and staff was like robots not willing to help at all.

Not the best. Mean. Didn’t give any value to me being a united silver member and lots of attitude.

Aisle chair was good and liked the foot bar preventing you from putting your foot in the isle, The breakfast on this international flight to Zurich was horrible (Europeans, specially, used to good food) may make this a dealbreaker for booking with United Airlines again. I agreed with my Spanish fellow passenger.

my seat got changed twice after checking on then boarding it had been given to a family so by the time they found a seat for me no overhead storage left. i ended up losing my Sony Headphones case because i could even access underthe seat in front of my when deplaning.

Nothing exceptional but all good. Business class seats are like the domestic Mint class on Jet Blue. Comfortable but not exceptional. Food is good but not superb. Flight attendants were better than US carriers but that is to be expected. However, not the caliber of Asian or Middle Eastern airlines. Very Lufthansa like but Lufthansa has slightly better seats, even though they are hardly best in class

Seat 14K (business class) had no cushion / would not inflate. It was like sitting on a stone bench the whole flight. Sleeping was impossible.

They blocked me from checking in online and they charged me lots of money

Everything was good with Tap Air Portugal. It was Logan Airport that was a problem. The fuel system was down and delayed my 10:40 boarding. I wasn't able to board my flight until 2:00 am...after that my flights were great.

Not have my bag forced to be checked when I had a carry on included on my ticket. Staff was very rude to me for asking why they were doing this. I was told there was no more room for carry ons but there was plenty of space in the overhead compartments

Poor. Our flight was delayed and they told me I would be fine to make my connection in Lisbon, I missed it. Then they told me my bag would be automatically loaded onto my new flight to rome. It wasn’t. It’s been 4 days and I still don’t have it.

The seats were not designed to comfortably see people in coach for more than 10 minutes

Checked bG chstgr was extremely high. Over $120. It was s bsit and switch knowing an international passenger would have t9 check a bag.

On time, politeness, food okay but entertneiment mediocre with only old movie and the so called new we’re 2 or 3…

Everything went very well. I would like to acknowledge the politeness and professionalism of the staff—they are superb. No complaints.

No legroom, have to pay for everything including water?!? Water is more expensive than beer?

We liked the crew. They were competent, professional and friendly. The only big negative was our departure was delayed several times and the airport staff did not communicate what the problems were and what we should expect.

Damage May baggage and I report the airport agant and they see it

Crew was very friendly. Need lay flat beds! More snacks

Good. Rxception is the Entertainment - movies and TV shows all out of date…

I liked the crew but not the uncomfortable seats and lack of movie and tv selection.

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.
