Excellent excellent flight! I’m sure it helped that the turbulence and the weather cooperated, but the staff was wonderful. The legroom was perfect and my husband is 6‘1“ and he felt perfectly fine. Best flight I’ve taken in a long time.

Excellent excellent flight! I’m sure it helped that the turbulence and the weather cooperated, but the staff was wonderful. The legroom was perfect and my husband is 6‘1“ and he felt perfectly fine. Best flight I’ve taken in a long time.

The service was impeccable both ways. I’m very happy to have had the opportunity to fly Swiss Air.

I have no Comment. Super clean, Fantastic Crew, Food was delicious. Also wanted to add the Zurich Airport. Super nice people everything is in order super clean.

I like it very much it was a good experience with an excellent service

Swiss messed up a Geneva-Zurich flight on a day with perfect weather. Then they didn’t even let people with almost no time to catch connections disembark first. Finally, luggage missed the connection of course and it took almost 24 hours for it to be delivered. We lost a whole day of vacation stuck in the hotel waiting for it.

The boarding of this flight was total chaos. For some reason, all passengers had to stand in a lengthy line at the gate to have our passports checked for the FOURTH time. No reason was offered for the necessity of the fourth re-check, and when we got to the end of the line, the check was perfunctory. There was little to no crowd control at the gate and in some cases, tempers were flaring. On the other hand, once we got on board, everything about this flight from start to finish, especially the quality of the food and the service, was probably the best I have ever experienced..

Really BAD check in experience. My bag was left in Geneva and I have not received it yet. I have been in Stockholm 5 days without clothes to change. The flight was good but very unhappy with the post service support.

We still don't have our luggages... flight was Saturday Jan 3rd and today is Wed 7th...even after fling the delayed/missing baggage report on saturday night and contacting SWISS (which is not answering) we still dont have our luggages...

I purchased a one way business class ticket from Geneva to Miami but the check in agent said I had an economy ticket and later upgraded to business class. This was not the case, I had a single business class transaction. I was forced to pay for my second checked bag. I am unsure of why this happened. But I won’t use Kayak again for business class tickets.

We're talking about a short-haul in-country flight.. there is no confort, no food, just the bottle of water. The seats are squeezed like hell and I was in the back-end of the plane, with one spare row left for the crew and to store excess bags that could not fit in the overhead bin.. Speaking of carry-on, some passengers should be better screened as their bags were simply too big to fit in the overhead bins.. ! How can this happen, and it was an A310, with 2 columns of 3-seater rows.. There is a pseudo-Business class, which is simply a section in the front of the plane where the same seats are occupied only 2 out of 3, on each side, leaving more rooms for the passengers and their bags. That's it.

Phx - ORD was nice 737 with starlink and the ORD - grr was ancient bare bones airbus with not even a power port lol

It was easy to board, and the staff was friendly and helpful. What could have been better is that I shouldn't have to pay extra for a seat that doesn't recline.

Was on the plane sitting longer than the actual flight in air was, boarded at 5:45p and didn't take off until 6:50p flight was only about 30 minutes long. Just was poor experience will booking more with American Airlines.

The couple in front of me were constantly talking over the announcement from the captain and this was annoying me.

The lounge was not accessible because it was located before the passport control, and backtracking was impossible.

Flight crew was super friendly and helpful. Food was frequent and honestly pretty good. Plenty of on-board entertainment. Economy seats are super cramped for such a long flight, but the crew allowed people to get up and stretch, and kids could wander with their parents, so we all made it work. Overall a very good experience.

Good crew. Boarding delays. Almost two hours wait for the bags in DC.

Safe made to destination. Late to start at GVA for icy reasons but we fought our next fly.

Great crew, excellent landing, good food. Over all great experience. Thank you!

The flight and staff was very good However: we could not check in using the website. We got the reminders and updated information but could not check in on either flight. And we did have the United App. Also just a tip for fellow travelers - going through customs in Chicago Ohare Airport it terrible.

roomiest flight in economy I've taken in years. Excellent experience!

I was booked to travel from Dallas to Nairobi via Chicago and Brussels and had been issued boarding passes for all three segments of my journey. At the boarding gate in Dallas, I was required to check my carry-on luggage due to limited cabin space. Despite my attempts to explain that I was traveling internationally and would not have access to the bag during transit, my concerns were not considered. I also informed the staff that I did not have a padlock to secure the luggage, but this was disregarded. Consequently, I had to hastily transfer essential items from my carry-on into my handbag. To my surprise, upon arriving at Chicago Airport, I observed numerous international travelers boarding with cabin bags that were significantly larger than mine. This experience left me extremely disappointed and led me to decide against using United Airlines for future international travel, a sentiment I have also shared with friends and family. Unfortunately, the onboard experience on the Chicago to Brussels flight further reinforced my dissatisfaction. The cabin crew appeared disengaged, indifferent, and lacking in attentiveness, resulting in a service experience that fell well below my expectations.

I want to highlight the crew members and their excellent work and professionalism. They work hard to make a long trip the most comfortable as possible, the food and drinks they offer are pretty good. And they are always asking if you need something else. I have had experiences with other airlines where you have to basically beg for a bottle of water. This is not the case. Highly recommended!!!

the blanket was great and pillow helped. really need a toothpick packed with meals

The flight was delayed. No information was provided as to the reason for the delay. There was only water offered during the flight.

Check in could have been a little cheerful rather than dour

Nearly every flight was delayed, I missed a connection at one point and the solution was unbearable. Added nearly 12 hours of travel time to my itinerary and was given no recompense.

Swiss air was a short flight to and from Frankfurt to Geneva. The crew was nice, and the service was fine. Would be nice if they had wifi available.

It was alright, you are sure about your bags even though they will be bag checked, you will get them back once you disembark.

Their service , specifically the way Lufthansa manages luggages is terrible
