Cons: None

Pros: Attention and comfort

Pros: Nothing

Cons: Leg room

Pros: The planes were well maintained. Good entertain emend choices. Food was decent too

Pros: The overall experience was okay, no food service and seats were not super comfy.

Cons: More leg space for a long flight and free snacks.

Pros: That we didn't crash

Cons: There should be food, or at least a snack, on a 5.5h flight. Also the seats are extremely small. I barely fit into normal coach seats, but with my 6'7" (200cm) I was extremely uncomfortable in these tiny seats.

Pros: The crew ok. Seats not comfortable

Cons: Serve snacks at least on trans-atlantic flights.

Pros: Flights arrived on time

Cons: Lousy crew at checkin gate, and on plane, they try and charge you for everything

Pros: The crew was very nice. The boarding was fairly organised. That’s about it.

Cons: I don’t know what the problem was with the air flow but it was hot and stuffy. The flight attendant tried to fix it several times but it was miserable. The seats are extremely narrow. No usb plugs and very little selection of movies.

Pros: Seat comfort was not terrible. Staff were good.

Cons: Tiny video display. Lousy pasta. Poor selection of films.

Pros: Fight was on time. BA Crew always do a nice job.

Cons: The entertainment on the flight didn't work. It is not easy to have two small kids on a 9 hour flight when the entertainment system isn't working properly. We did bring our own items to entertain our kids but with the limitations on what you can carry on we were banking on them being able to use the in flight system.

Cons: Antiquated and glitchy entertainment system on the 747-400

Cons: Overall, I am disappointed in Kayak for listing my round trip flight as KLM, when in actuality, only one short connection of this flight was actually KLM. My itinerary said KLM all over it, but in the fine print it said "operated by Delta." This is dishonest and misleading.

Pros: The seating in upper class is unconventional and uncomfortable.

Cons: Reconfigure seating in upper class. We will no longer be customers for that reason alone..

Pros: The crew looked after us well

Cons: It was all good

Pros: the crew was very polite and professional.

Cons: the aircraft is small and confined, only two toilets for the entire economy level passengers for a 6 hour flight. the online entertainment lacks variety and the food was okay.

Pros: I liked the attentiveness of staff and there was excellent communication between SWISS airlines and customers.

Cons: I honestly had no issues with my flight.

Pros: Never got on the plane due to weather restrictions in the connecting flight prior to this flight. Called SWISS customer service on a Russian line, were told to get a paper from another Russian airport that no flights were leaving the city. Did that. when arrived to Moscow no SWISS customer representatives were at the stations and had to end up buying a completely new ticket to get home.

Cons: Have customer service representative available at the airport 24/7 knowing that some people arrive from all parts of the country.

Cons: crew at the gate.

Pros: Taking off on time. Good service and helpful from all the stuff.

Cons: Keep it like that

Cons: Be careful when booking as without paying extra for a food package (which I didn't know about through any communication with Kayak or Norwegian airlines) you won't even get water. The crew didn't even make eye contact to those of us without the food package.

Cons: Flight was canceled after waiting 4 hours due to plane technical difficulties. No customer service to get to destination. While I know I will get a refund for Norwegian, not sure I will with the connecting flight. Had to go to a different airport and pay a lot more money and getting in a day. United

Pros: Cheap!

Cons: Staff were friendly and professional. The food was okay but nothing special. The seats were good, but a little firm which may cause problems on longer flights.

Pros: The socks offered in business were comfortable and nice looking. The red wine was good.

Cons: The food was just average and the seat not too comfortable

Pros: The crews were pretty great!

Cons: The regulating of the temperature.

Pros: the crew was wonderful, we got a nice Wrap and water, wine or coffee for free, not all airlines serve it anymore, we were on time and I got whatsapp message with updates of the flight

Pros: Fantastic gate agents!

Cons: The food was terrible.

Cons: It’s very very poor and flight radar is below average

Pros: Seat back tv’s

Cons: Flight was delayed over 3 hours, food was mediocre at best

Pros: The seats were nice and the food was unusually good

Cons: More water brought to the seats. The landing was strange. The pilot pulled up on the first approach and when the second approach was completed the steering was stuck. They ultimately got the steering to work.

Pros: Great crew, decent food, plenty of wine and other drinks, on-time departure and arrival.

Cons: Uncomfortable cramped seats, USB port on seat-back video display does not charge a connected device.

Pros: In general everything is very good- clean, professional, friendly.

Cons: I am not crazy about how they board the plane (random) but it works fine. Was in economy and the seats felt smaller than other (domestic) carriers.

Pros: The price

Cons: Have a bigger airport in Reykjavik. Being bussed between connections is not efficient or comfortable and leaves little time in the layover portion of the journey.

Pros: the seat was comfortable, the cabin temp was perfect, and the views were incredible

Pros: That we didn't crash

Cons: There should be food, or at least a snack, on a 5.5h flight. Also the seats are extremely small. I barely fit into normal coach seats, but with my 6'7" (200cm) I was extremely uncomfortable in these tiny seats.

Pros: Seat was both comfortable and spacious. Crew were very attentive and personable.

Cons: Really great flight. Can’t say enough about it.

Pros: the crew were amazing. The food was good. 20 minutes late in a snowstorm, amazing. Seats were comfortable. I will definitely fly Lufthansa again.

Pros: Love Lufthansa

Cons: Flight left without us even though they knew our flight had landed and we were on our way. Then they rerouted us with a longer flight and our luggage didn’t make it.

Pros: Great crew, smooth flight

Pros: the seat configuration is 2/4/2 so if you get a seat by the window, you have your significant other or friend next to you and no one else which is nice. Food was decent.

Cons: Entertainment didn't have any interesting movies or TV shows. Bottom of the barrel. No coffee or tea was offered before landing and it was advertised.

Cons: flight was late.

Cons: Cabin crew makes way too much noise on an overnight flight. On these flights, the focus should be on letting passengers rest, and limiting announcements, even if that seems to take away from the perceived level of service.

Cons: We paid extra for an exit row with more leg room and were moved to a standard seat. We were also separated from the rest of our party. We spoke to the help desk to try and resolve the issue they told us the seats we were moved to also had extra room but when we boarded the plane this was not true.

Cons: The first class seats need updating

Pros: The overall experience was okay, no food service and seats were not super comfy.

Cons: More leg space for a long flight and free snacks.

Cons: Weather did not cooperate, not airlines fault....

Cons: We had a three hour departure delay in Munich

Pros: Attention and comfort

Pros: Flight attendant warm, courteous and authoritative at same time.

Cons: Seat hard. Space tight. I am 6’4”

Cons: The touchscreen was so buggy and unresponsive that I opted to sleep instead of trying to find something to watch on it.

Pros: Competent crew. Arrived early.

Cons: The plane was so old it had signs that read, no smoking in the lavatories. The entertainment screen was small and slow to respond. Should be in a museum.

Pros: Seat comfort was not terrible. Staff were good.

Cons: Tiny video display. Lousy pasta. Poor selection of films.

Pros: British Airways code share is always nice

Cons: Older 747 not quite as nice as the Dreamliner but it made it!

Pros: plane was not full so plenty of room to move around etc

Pros: Fantastic gate agents!

Cons: The food was terrible.

Cons: Seats in economy section are very close together . There is not enough room for knees...especially for such a long trip.

Pros: Yes

Cons: Everything was good

Pros: Almost everything, especially the crew.

Cons: Don’t feel like anything should be better to be honest

Pros: The in flight service was fantastic. The attendants were friendly and always smiling. The pilots flew the plane with Swiss precision. I had an economy ticket and they fed us twice and had at least six beverage passes to keep you hydrated. A blanket, pillow and ear buds were provided as part of the seat. Norwegian Air does not even cover a glass of water. They are pathetic. We will travel with Swiss Air again.

Cons: Internet service is invoiced by the megabyte and not the flight. For flights of this duration, a lump sum is a better idea.

Pros: All great!

Cons: if my luggage would of arrived with me, Swiss airlines left behind 2 of 4 pieces of luggage in Zurich! I hope I can get them back!

Pros: Taking off on time. Good service and helpful from all the stuff.

Cons: Keep it like that

Pros: The crew was very nice and positive. The seats surprisingly reclined quite a bit. The dinner was actually good.

Cons: The offer of wine. The wifi options.

Cons: I do not like that mono do sale me a ticket with no baggage and never will by a ticket from this company again!

Pros: In general, everything was ok aboard the plane.

Cons: The plane was supposed to leave Lisbon at 5:00 a.m. but because of computer problem it left at 5:50, a delay that caused everyone to scramble to get to their connecting flight or even miss it.

Pros: Comfy seat.

Cons: Plane was late, crew was surly.

Cons: None

Pros: Although I was in Economy, I got a window seat with no one next to me, which made things a lot less cramped.

Cons: The plane was extremely hot I was sweating the entire trip. Also this was a red eye flight and I would have preferred they keep the lights off for the entire trip.

Cons: Better entertainment

Pros: The crew tried to be helpful and the flight was on time and uneventful.

Cons: Having purchased our 2 tickets together at one time months before the flight, it was very upsetting that we were placed in two different rows away from each other for a longer, international flight.

Pros: Nothing bad experience and poor foursomes service. Will never fly again with them

Cons: Customer service is abysmal. Didn’t get offered a drink or food until 4 1/2hrs into a 8hr flight. Flights delayed and cancelled and didn’t even look after us half decent. No food vouchers or taxi back to airport. Waiting in lines for hours with no one at desk. I could go on but no room to type

Cons: Lost my bag. Bumped me back down from Premium to Economy and tried to avoid refunding me. This airline has no concept of customer service.

Pros: Zero frills. Not a glass of water, a set of head phones or glance of the staff unless you paid for it. You get what you pay for and nothing came without a cost

Cons: More leg room would have been nice. Maybe one complimentary drink for over a 7 hour flight. Don’t forget to fill up your water bottle

Cons: It would be nice if they would give all passangers free food and drinks

Pros: Nice crew

Cons: Comfort. Seats were very uncomfortable with absolutely NO leg room. I fly a lot and this was one of the WORST leg room experiences I had.

Pros: Everything was easy

Cons: Business class seats are snug for big people compared to other airlines

Pros: crew was nice

Cons: First time flying with a partner through Delta, so they stuck us on a Virgin Atlantic flight meaning I didn't get my free Delta check in bag (a fee of $60 each way) when I have gotten it every other flight I have ever taken with them. It was also 2 whole hours late in boarding.

Pros: Premium economy was perfect, smaller cabin with less people, great flight.
