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

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

The flight attendants are amazing. The plane itself was not in good shape for passenger comfort. A good share of seat reclines were broken so they went back an unlimited amount, which meant the person in front of me was fully in my lap (the crew helped me find another seat but that would not have been possible on a full flight). Moisture from the ventilation was also dripping on me. And the entertainment system is almost impossible to hear.

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.

Poor. Seats uncomfortable. No leg room. Hot and humid the whole trip. Food and staffs were ok.

Flight was cancelled due to technical problems with the aircraft. It would be nice if SWISS would invest in new aircraft; that would for sure minimize the technical issues with (old) aircrafts.

So disappointed, the flight from Zurich to Sarajevo was delayed for two hours for no reason, they were also shifting gate several times prior taking off

Overall a good experience, the flight was on time, the crew very attentive and friendly. However the seats are too cramped, there is no space, and as soon as the person in front reclines the seat, it's literally in your face.

Bag lost. Lost bag recovery process is an unsatisfying customer experience. Because 1) bag is still lost but also 2) the process is outdated and form-heavy and 3) in our case also involved a long line.

We sat in our seats on the tarmac for almost 3 hours due to storms. They would not give us water or a snack. We were to depart at 7.30 pm and it was about 10.30 when we took off. No dinner until much after that. Beef type noodle dish was terrible with about a teaspoon of beef in it. The breakfast sweet waffle with egg and sausage inside was horrible. An English muffin sandwich would have been much better. Food was the worst in all of our years of traveling the world.

Was never allowed on and not refunded the full amount of the ticket plus charged a $300 processing fee.

The staff was bit rude when I asked for an extra drink after one beer, asked for one wine glass.

I was deceived on the Kayak site expecting a ticket, but instead finding a "standby" reservation. When I tried to change the ticket, I paid almost twice the price of the original ticket. Then, the airline refused to give me the reserved seat I had chosen and paid for. I think I deserve a refund for this leg of my trip because I was doubly charged and did not receive what I had paid for. I put in a complaint with Lufthansa because the ticket was sold originally sold as a flight they listed. Someone here needs to take responsibility.

Excellent service; they helped me reschedule so I can fly in an earlier flight

I booked extra leg room, due to seat neighbor i now consider extra shoulder and arm room as well. Seems like the seats shrink in width now The crew was very friendly and professional ( 100%). Food was good not great, breakfast was bad, a dry slice of bread would have been better. Facilities clean.

I think they overbooked Frankfurt to New York and bumped me off. This changed my return travel I arrived home about 4 hours late. Almost 24 total travel time Totally unacceptable Would not travel with United

Flight was delayed over one hour and I had to pay to select my seat, even though my booking supposedly had free selection (I paid extra for this at time of booking)

Flight was late arriving. So, we left 25 min late. Pilot made some time up during the flight. Therefore, we arrived alittle past original time.

Insulting. Lufthansa flight from Munich to EWR had us getting our luggage when we were told in Florence that it would follow us to Indianapolis. It did not. Then very slow security in EWR caused me and three other passengers from Lufthansa flight from Munich to miss the boarding closure. Behind me were two elderly grandparents and their ten year old grandson. We were all refused entry on a plane to Indy that was still at the gate. The doors had not even closed inside the terminal yet. No apologies or compensation offered. Not even a meal voucher let alone a free hotel stay for our inconvenience. I m not sure what the other three passengers behind me did ( they were elderly with a grandson, recall), but I stated 12 hours overnight in a chilly EWR airport until next flight to Indy at 850 next morning.
