No choice of food was given, and I was served leftovers, so they were returned back. the crew is unfriendly and harsh. Need to be trained on communication.

No choice of food was given, and I was served leftovers, so they were returned back. the crew is unfriendly and harsh. Need to be trained on communication.

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.

At boarding, the locations where we had to have our passports checked prior to boarding were very unclear. Occasional staff wandered around telling people, but in busy area of the terminal this was not obvious. It was also located well after the check in desk in terms of walking to the gate. The Premium Economy service was attentive and warm. The only big draw back was lack of restrooms, and no division or even curtain between PE and Economy.

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

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.
