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.

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.

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

The cushion of the seats are old and very thin. The food can be more tasty or come with salt packages

Excellent Airline. Food, crew and comfort was perfect. Entertainment screens were old. Didn’t like them.

Crew members were good. Seats were packed and too tight .

Staff at the airport wasn't helpful or friendly. Probably the worst airport experience I have ever had, going and coming. The staff on the plane was better. Still not super friendly or personable. However, they were not rude like airport staff. They ran out of certain menu items. Maybe could have been prepared better? Overall just ok.

the cabin was kept too hot. couldn't sleep as a result

Crew were unfriendly, touch screen for movies didn't work very well, seats were tight and uncomfortable

Awful seating. Bad food. Staff only have one bottle of water and no cans.

Worse worse worse, i would not recommend this airline to anyone. Istanbul airport maybe State of the Art facility but staff is rude, only works if they get tips, and they push you to give tips even though my family had spent $50 in tips. Airline staff doesn't speak english so you really can't understand them. It was a nightmare travelling with Turkish. Never again.

My flight was canceled 1 minute before boarding. The customer service was owful, no one could tell us what was going happened. I spent 30hrs instead of 15 from Washington DC to Brussels. No apologie or help

Boeing 777 is a bad choice for a such a long flight.

I wouldn't know what the flight was like. AI canceled my flight reservation!! There's no way to speak to an actual human to fix the issue! NEVER AGAIN! ALWAYS BOOK YOUR FLIGHT DIRECTLY WITH THE AIRLINE NEVER GO THROUGH KAYAK OR JUSTFLY.COM!!

I’ve been traveling for 20 years. I tried Turkish airline for the first time horrible horrible service and it would be my last time even if I get offer for a free ticket, I will not accept it. They have races and the worst Flight attendant

It wasn't good. I didn’t understand. They changed 320 dollars for 2 luggage. My ticket was regular and I paid almost 1200.00 dollars. Why they did charge? I want my money back.. thanks Yılmaz polat

Missed it by a couple minutes and couldn’t find an alternative flight so had to spend the night in DC and after much shuffling from 1 airline to another managed to get a United to Frankfurt.

There were only 2 toilets and one of them did not work in business class. We are not allowed to cross classes so had to wait in line to use the toilets!! The entertainment touch display was finicky and did not work all the time.

The flight and crew were good. The customer experience on the ground could have been better. We had to reschedule our flight because of a delay on the previous flight. The attendants working the desk in Washington DC were not helpful. They told us to scan a QR code and that would get us rebooked. Why couldn't two people standing at their computers do this? We had to chat with someone to get everything figured out. It was extremely confusing.

good entertainment package but rather small seats for business class

The male attendant has zero personality. It seemed like he was over worked or hated his job, not once did he smile or made any contact with the people on the plane. Strictly business and call it a day!

Our flight was delayed for over an hour due to weather, and it had already been a long travel day. However, the crew was calm and compassionate, listening to every complaint with genuine concern. They got us home safely without incident, in spite of all of the obstacles. I’m grateful.

Bad! Disaster!! The LH419 was cancelled after 4 hrs on board with no AC and no toilets

We had almost a 6 hr delay, primarily due to weather, the e problem was that they communicated this delay and its length very poorly. The boarding was chaotic - even though they had hours to figure it out! The plane was an old 747 whose touch screens barely worked and there was a faulty USB port under my seat rest (something that wasn't labeled as being there) They organized my delayed luggage well. And I could get updates on the Lufthansa website. My shirt connecting flight charged for everything except water. Coffee was over 3€

It was freezing. I asked crew member for a blanket and was told it might be in front of plane but I never got one. I turned off all the vents but still froze.

My schedule flight was rebooking and changed to Chicago, then I did not used the flight from Dulles to Savannah
