0lane 2qs on tim3. Very bad food. No free wifi, only for texts. Entertainment poor and hard to access.

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.

We had seats between the bathroom and a screaming baby, and did not have enough room to lay my head down on the tray table. Not ideal.

Very nice crew and great food. Easy to board just wish the flight could be shorter or seats more comfortable or more room to walk around when you get cramps in your legs from sitting so long. Crew was great and attentive and really was good food.

Terrible - we needed tp change the flight and it was impossible. They ask for a price that was higher than buying a new tickets from another airline. Will never flight Swiss air and Luftgansa again.

My experience was wonderful. The professionalism of the crew was exemplary 🙂. The meals were wholesome and tasty. I have no complaints

As an ex airline employee in my home country of Jamaica, it was wonderful to see that Swiss Air has maintained it's exemplary service. The crew was both pleasant and professional. The meals were wholesome and tasty. My brother and I traveled and we both agree that our amazing vacation started with the excellent experience with Swiss Air. Continue to keep your standards high 🙂

Everything was smooth and great. I didnt like that they talk so much on the interphone during the flight.

Even though I paid extra for more room, we were very cramped and the seats were hard. Also, when we checked in they did not post the gate we were to arrive at even though we were half an hour away from boarding. The agent did not know either. Actually, the flight from Porto to Zurich did to have the gate posted, and there were very few agents in the boarding areas who could help us. I would never fly Swiss Air again.

Swiss is the. Only airline I use when I go to Europe. They are on time and they are fantastic!

Great plane and flight attendants. The person next to me had a DISGUSTING smelling mouth and breath, so that was nasty to deal with the whole flight. Brush your teeth, people! Condor was amazing, though :-)

It would be nice to have a cleaner facility, it was hard to access it. It was always full of people working in that space. The covers and especially the matt of bad quality and old. Many times reused. I would not use it. Food: the bread rolls were old, and food had strange choices. Chicken was terrible.

There was some nice staff when I entered and left, but the thrre flight attendants who served us were very brusque and rude. I have celiac and when I checked in, I tried to find the option to make sure my meals (stick on a 10+ hour flight after a 3 hour flight and short layover) were gluten free because I didn’t have time to get anything. Couldn’t find the selection for it, and every part of the meal and purchase options were gluten, so I didn’t get to eat. During check in the allergies section should be easy to identify and check so this doesn’t happen. Having more options for gluten free at this time should be easy.

Internet was advertised in-flight but not accessible. The foot rest in premium economy was stuck. For both nobody I asked was able to provide an answer/solution. However, this will not stop me from booking premium economy again, which I upgraded from my initial economy I had booked for my outbound flight YYZ to FRA.

Great flight, nice options for food and beverages. Fairly comfortable seats for a large person

Business class: or fist class: Seating absolutely terrible, same seats as everyone else , no space, we could not fit our knees in. I was sitting sideways since nobody else booked this business class. I wish we would have an option to select a business class for the main journey between USA and Europe, but regular class for the short flights in Europe.

The seating was exactly same as the rest of the plane. We had no space for our knees. In fact it was the tightest spacing of the seats I ever flew with, on a very old plane. (and we flew all over Asia and Europe) The same chairs. We were the only passengers in business or first class. Obviously funny.... The only difference was, we got a sendwich and we were offered a drink. Rest of the plane got a bottle of water.

The crew was great. Good etc was unacceptable for an overseas flight. Wine with a meal should be complimentary. Seat comfort /space horrible and I am 5‘3“ with heels on. Short haul probably ok but not on long haul flights

It was extremely difficult to upgrade my partners flight over the Internet from economy to economy, plus. Then it said clearly the checked luggage can be 32 kg. At the check-in counter in Hamburg, we had to pay 100 Euros ( $122.17) for the only 31kg peace checked luggage. We were told because the change was made less than 24 hours before the flight , the luggage weight would not be upgraded. Then they offered me that for €90 I can upgrade at the counter from economy to economy, plus so we can sit together on the flight from Frankfurt to San Francisco. I happily agreed and was charged. €99.($120.95), which I noticed too late. Especially about the Euro 100 up charge I feel upset and it’s a unfair way of doing business!

Take off was not good, too hot inside the plane and seats are beyond uncomfortable.
