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

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.

Didn't make the connection as my primary flight was 3 hrs late, I had to basically beg to be put on a different airline to continue my trip otherwise I would have been sitting on the airport for 8 hrs

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.

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.

Lufthansa has a bag policy unique to Lufthansa. We all had a small carry on and a backpack (personal item) that we carried with us through multiple other connecting flights, no problem. With Lufthansa we were charged 80 euros each for the carry on at the gate, for this one flight. When asked they said they made an announcement… problem being that we had just arrived to the gate from a connecting flight and didn’t hear an announcement. While we were standing at the counter paying the ridiculous fee several other people were stopped, while countless others boarded with the same type of luggage and were not stopped. Crazy. Good news though, when we got on the plane half of the overhead bins were empty! After an already horrible experience the lady at the counter was also terrible, so that helped round things out.

Delayed over 2 hours. Bring your own snacks or prepare to pay. No entertainment and no plug plugs for charging.

I remember flying with Lufthansa many years ago, and it used to be an amazing airline with more technologically savvy and roomy planes, but unfortunately that isn’t the case anymore. The space between the seats is much smaller, which is ok for short flights, but definitely not for across the Atlantic flights. Not sure if I’ll opt for Lufthansa the next time, maybe just if necessary.

Boarding delayed 1.5 hours. Ended up sick because of all the delays and lines waiting around airport and boarding.

They failed to make sure all luggage made it onto the flight. I had to spend a week on vacation with no clothes.

No internet for most of the flight. Very narrow seats. Food was bad. Flight was nearly an hour late with perfect weather, crew offered no explanation or compensation.

Gate agent required us to check our perfectly legal carry on bags due to a supposed lack of overhead space. After seating, we saw nothing but empty space in our seating area. This caused luggage to miss connection in Athens, and we had no bags in Mykonos. Totally avoidable and unacceptable. My last U A flight !

Enough leg room, no drinks or snacks. Looked like they were very good with the children

Would not accommodate my request to bring my my jacket I left on the plane.

Food was mediocre. In flight entertainment lacked live TV. Crew was fantastic. Plane very comfortable if a bit worn.
