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.

Overall a very good experience.

I couldn’t make my first flight due to weather delays trapping us in the town we were in. Then I had to buy a new ticket

Airport terminal was outdated, flight was on a small jet with no wifi

The seats were comfortable and we had leg room. Great entertainment.

Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.

I feel bad, but Swiss airlines is not an airlines I will ever fly again. Their cabins are basic, seats are extremely uncomfortable, crew is a hit or a miss with service. What's worse is how they make you feel they are there to make money and not make your travel needs be met or make your travel a pleasure. They charge for 2nd bags, seat selection and felt like a budget arinines frontier/spirit airline attitude and approach. Their business class is from the early 2000s, basic. Additionally, planes going to India, are old, falling apart and not maintained. Even the crew mentioned this is typical of the airline having older planes going to India. Panels detached and loose or stuck with duct tape, seats scruffed up and dirty, seatbelts roughed up. The scariest thing was when I saw a window panel next to where I was sitting loose and dangling. The crew mentioned it's only cosmetic and assured the integrity of the plane was inspected by the maintenance crew. This is where they confessed about planes going to India being old. I UNFORTUNATELY would NOT recommend Swiss airlines to anyone and will NEVER fly with them again!

Ability to watch movies.No earbud sound system.Marginal beverage service.Unexplained late take off resulting in VERY tight connection in LA which proved maximally stressful.

Last minute gate change nearly caused us to miss our flight. Change was not announced or displayed in the main board at the old gate. Terrible communication. When we landed we had to wait 20 minutes because there was another plane at the assigned gate. Not the crew’s fault, but adding 20 minutes to a 45 minute flight sucked.

Sitting in 1A I can honestly say, that being a first class seat the leg room is sub par. The crew was attentive and friendly. Food was a a cheeseburger with fries. Fries on an airplane came as expected: no very crispy 😉

United Premium Plus or Premium Economy was almost twice the price as regular Economy, but the value is much worse. The seat is a bit wider and more comfortable. but not by much. The food was not good, felt like cheap fast foods on a little bit of silverware. The flight attendance service was the worse, not much attention to passenger, no helping of any kind. All in all, United Premium Plus is not worth its price, and was much worse than its Asian or Europe counter parts.
