Business class seating in Swiss really is just Economy seating minus the middle passenger

Business class seating in Swiss really is just Economy seating minus the middle passenger

The flight itself was fine, but due to a snow delay my connection to Lisbon was delayed by six hours. Despite this, Swiss Air still managed to lose my luggage. Not acceptable. Someone else on the flight also lost their luggage.

Bad experience overall. Crew did not provide food for our 2 year old (even though we specifically bought a child infant seat for her and literally bought another full price flight), which was unacceptable. And we had to pay $310 each way to carry our ski equipment even though they advertise it as something that is free. Tickets were purchased the same way as usual, but they told us we had Economy Light tickets (I never elected to have such seats). Just plain manipulation and false advertisment. Very disappointed overall about this airline.

The trip was great until my luggage was lost on transfer from United to Swiss. It took Swiss 3 days to get my luggage to me though it was located almost immediately.

Made us gate check carry ons Then didn’t get them on the plane. Service they used didn’t deliver our carry ons for more than a day Total mess

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

We’ve never been more uncomfortable on a flight than we have on this particular one. The seats in front of us reclined so far back that when the person reclined their seat of broccoli, it almost hit me in the face and left me with literally no room to move that said I had to recline my seed in which made the person behind me upset. It seemed like the seats also would recline without even pressing the button in the armrest and would unrecline as well for that same reason, and it also seemed that some seats reclined more than others. The bottom cushions of the seat were so thin that even after one hour of an 11 hour flight, our tailbones were so sore. It seemed like an overall old airplane. It also didn’t have individual air vents and it was extremely hot the entire flight. Several passengers were commenting on how hot it was. The breakfast was some kind of flavorless triangle, puffy egg, laying in a watery bed of steamed peppers and onions and spinach. It was not appetizing at all. The flight crew was extremely nice so that was a nice thing this flight attendant. They let us try different types of Swiss sodas, which was really nice and the dinner was actually delicious but still overall given the other considerations. It was pretty much a miserable flight without basic seat comfort.

Food used to be better and comfort was not attainable after 5 hours everything starts hurting.

horrible.. they cause such a problem and my daughter 14 years old was stranded in san francisco

I can’t even the whole trip was a catastrophe

the entire flight felt off. The crew seemed uninterested and disengaged. The food service was really bad - overcooked, bland, weird food service. They actually woke us up to serve chicken wraps in the middle of the night, after dinner and before breakfast. Made no sense. Ultimately, I was glad they did though, because the breakfast had been held for so long it was inedible. Eggs, potatoes, sausage - all disgusting. We were asked to "honor" the lavatories for premium customers and stay in our own cabin: this was also strange. So people in economy didn't pay enough to use the closest toilet to them??? It's a toilet. All in all, not the experience I have come to expect from United Airlines. The return flight from Paris to SFO was better, btw.

They delayed the flight from 9:00 to 11:55 At 11:45 they canceled the flight. I paid a premium price for the tickets with poor service

The 777’s economy seat’s legroom was more tolerable than expected. I appreciate the reclining mechanism which slides the seat forward to minimize cannibalizing the space behind. The food was terrible: very salty.

Seats are uncomfortable. This has been a trend in the industry for decades. Trying to fit more seats on each plane to increase profits at the expense of the passenger.

Staff were good. My seat was in need of repair, but for a short flight was not problematic. Usual basic snack and drink setup that you'll find on any US carrier. Over, a decent, basic flight.

Flight delayed for more than 16 hrs and no effort was spent to provide an alternate

We had turbulence ever 1/2 hr or so and the captains announcements were SOOOO LOUD

it was a very short flight so my expectations were low.

Entertainment kept turning itself off. Gave up on watching a movie.

Very disappointing given gate agent behavior. Filed a formal complaint with United.

Cancelled flight, wasn't refunded paid selected seats. Poor customer service. Called airline and they didn't realize the flight was cancelled until several hours after the email notice was sent.

The worst with the trip was the space in economy, my knees are still hurting. There was no way to control personal air by turning a knob above you, it was way to hot on both rides. During the night flight they allowed 2 people from across the aile which was narrow to sit and talk for 7 hours while also using tablets and the flashlight from their phones pointing into the row where I sat at times. They allowed people with way too large baggage to bring onboard. I paid way too much for the ticket ($1,364} for economy. Kayak misinformed me to get cancellation insurance that was only valid for a very short time (less than 12 hours) and was over one hundred dollars. Hotel booking was incorrect, I had the room booked myself at the hotel, only double or larger rooms available which I paid over 400 dollars for. I will never fly with SAS again unless there is no other alternative.

Crew members were excellent. The seat wasn’t the best as well as a food options.

5 of my 7 pieces of luggage are missing and they cant call to find out where it is. I have to fill out a form and wait for them to mail it to me in several days (if they find it). That does not work for my travel itinerary. I need my full ticket cost refunded please.

Fantastic. The only thing - out of my six luggage one was lost in Copenhagen, however it was delivered Home 3 Days later so all great..

The crew was friendly, the flight was pleasant. Thank you for your service!

Our trip plan from Kayak stated we were flying SAS. That was not true. The first leg was a Delta flight. We wasted 25 minutes before finding out to check in with the correct airline. Then our SAS flight for the second leg arrived 25 minutes late, and our third leg flight with SAS closed the gate knowing the flight delay was SAS’s fault, and that this flight would only be backed up 5 minutes. The final kicker was that between Delta and SAS, they lost all our checked luggage.

Flight was completely full January 9th? I problem i had the stewardess was bumping into me constantly walking by? very annoying.. on Austrian air I dint have this issue at all...

Amazing! Everyone was so nice and the food was so good!!

Terrible customer service. The flight attendants were rude. We experienced significant turbulence for a large portion of the flight and there was very little check in from the flight deck. The space was extremely limited to the point where it felt like torture. Never again

Lufthansa cancelled our flight from Los Angeles to Naples Italy on March 10 for scheduled flight on March 12 Very stressful experience trying to arrange alternatives. Will never fly again with Lufthansa

Service and food were excellent. Incredibly friendly and competent staff. Flight was delayed over and hour and I had to run between terminals to get my connecting flight.

Late flight Delays Poor service Poor staff Worst airline ever

Lufthansa still has a good level of quality compared to US airlines, especially with respect to (1) food quality - actually tasty, (2) good French red wine - free, (3) good movie selection. Also my ticket price includes 1 free check-in luggage, while some other budget airlines sneak in an extra $150 for a checkin.

The food could be better, more snacks. And have some plugs to chargue the phone.

Everything was really great just The aircraft was too old and sounded it will break during takeoff

Extremely pleased with the crew. Best flight attendants ever! Very friendly, genuinely caring and attentive.

Best flight attendants ever! Very customer and service oriented, courteous, professional and helpful.

Cheapest airlines I have ever been on. I got downgraded and never got on united. I got rerouted through Vancouver onto jetwesf

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.

The flight I initially booked from Los Angeles to Florence. I made sure had a layover of about 90 minutes in Rome, so there’d be enough time to connect. A couple weeks before the flight for some reason I was updated that that flight had changed and I was only gonna have 60 minutes to connect. From LAX we were delayed by 45 minutes meaning making the connection was unlikely. The crew informed me that my connecting flight would not wait and they would rebook me on one four or five hours later. I wasn’t happy, but I accepted it. It is what it is. Except when we got closer, two separate flight attendant approached me eagerly and said they had great news that my connecting flight would in fact wait for me, but I needed to hurry through the airport so they didn’t have to wait too long. I was first off the flight. I ran about 4000 steps. And got through passport control all in under 15 minutes. When I arrived to my gate, I was greeted by a flight attendant there who was completely indifferent, said they didn’t hold the plane and they just closed the doors. Had they even held it for two minutes I would’ve made it. She simply told me that the flight attendant on my flight lied about the plane being held, and that they do it all the time. These were all employees of the same company ITA. I was absolutely livid at her indifference and having been lied to and then having to wait five hours and waste a day in Europe at an airport.

The flight was canceled and we have not received the refund

They lost my checked in bag and have not helped me.

First, ITA lost my bag and the baggage team showed no regard in trying to find it. Second, I had paid for priority boarding as part of a first class ticket and instead they disregarded boarding groups and we all boarded at the same time. Third, wasn't allowed to select my seat in advance even with a first class ticket. When I was assigned bulkhead, I was told I would need to pay to change my seat. Overall, very disappointing experience.

The seats needs to be spruced up , for a long flight very uncomfortable , cushions are worn out but everything else is very good , crew is great.

I guess that was fine with ITA but the Rome airport is so difficult to navigate with so many checkpoints getting new tickets from what was originally given to me

I did not leave to Italy yet. We had technical problems on flight from SF to Maimi and had to land in Denver and wait for another plane to take us to Miami, so I missed my plane to Italy. I am still waiting for the Agency to fix my flight till today the haven’t done anything and I am paying for my Hotel stay. Everyday they are promising to fix my flight, they are not doing so and they are not even looking for another solution

My seat was broken and ducted taped and my monitor did not work the entire time over 8 hrs sitting. And I had no books or anything with me

my flight from Rome to Boston was on a very old plane. My video and audio did not work.

Good with timing of flights. The crew was exceptionally unfriendly. I heard more than one person say this. And even with the aisle, it seemed more uncomfortable than usual. The movie selection was old and poor, but the dinner was great - the lasagna and tiramisu.
