Checking in and crew were great. Seats in front of you in economy recline so much that you can't get out of your seat. I guess thats why its economy....

Flight was on time. Could have been a little more comfortable. Baby cried all night.

The chicken on the flight Boston to Zurich wasn’t very good. It was bland passable. Too much sugar in the Cole slaw. Cabbage is an amazing veg and can be much more crisp and alive. Flight attendants were Wonderful! Seats were a bit beat up but okay. In economy it was tight when the person in front learned back the screen became too close.

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.

Bad experience overall. Crew did not provide food for our 2 year old (even though we specifically bought a child infant seat for her and literally bought another full price flight), which was unacceptable. And we had to pay $310 each way to carry our ski equipment even though they advertise it as something that is free. Tickets were purchased the same way as usual, but they told us we had Economy Light tickets (I never elected to have such seats). Just plain manipulation and false advertisment. Very disappointed overall about this airline.

Poor. Seats uncomfortable. No leg room. Hot and humid the whole trip. Food and staffs were ok.

Flight was cancelled due to technical problems with the aircraft. It would be nice if SWISS would invest in new aircraft; that would for sure minimize the technical issues with (old) aircrafts.

So disappointed, the flight from Zurich to Sarajevo was delayed for two hours for no reason, they were also shifting gate several times prior taking off

Overall a good experience, the flight was on time, the crew very attentive and friendly. However the seats are too cramped, there is no space, and as soon as the person in front reclines the seat, it's literally in your face.

Bag lost. Lost bag recovery process is an unsatisfying customer experience. Because 1) bag is still lost but also 2) the process is outdated and form-heavy and 3) in our case also involved a long line.

They left a little late, contributing to our missed flight.

United did a good job of communicating before the flight, but a simple notice about the expected time for the completion of repairs to the broken navigation services (which closed the airport for the day) would’ve helped to clarify our expectations. With so many cancelled flights on the 21st of September, a little certainty about our own departure would’ve helped. Because of the disruption, the plane was quite empty, and at 6‘5“ I was able to steal a little extra legroom from the empty adjacent seat. However, I am still waiting for the day when I can sit in a standard economy seat and simply straighten my legs. Cabin crew were amazing. Great attitude, and moments of fun with passengers.

We sat in our seats on the tarmac for almost 3 hours due to storms. They would not give us water or a snack. We were to depart at 7.30 pm and it was about 10.30 when we took off. No dinner until much after that. Beef type noodle dish was terrible with about a teaspoon of beef in it. The breakfast sweet waffle with egg and sausage inside was horrible. An English muffin sandwich would have been much better. Food was the worst in all of our years of traveling the world.

Was never allowed on and not refunded the full amount of the ticket plus charged a $300 processing fee.

The staff was bit rude when I asked for an extra drink after one beer, asked for one wine glass.

I was deceived on the Kayak site expecting a ticket, but instead finding a "standby" reservation. When I tried to change the ticket, I paid almost twice the price of the original ticket. Then, the airline refused to give me the reserved seat I had chosen and paid for. I think I deserve a refund for this leg of my trip because I was doubly charged and did not receive what I had paid for. I put in a complaint with Lufthansa because the ticket was sold originally sold as a flight they listed. Someone here needs to take responsibility.

Excellent service; they helped me reschedule so I can fly in an earlier flight

I booked extra leg room, due to seat neighbor i now consider extra shoulder and arm room as well. Seems like the seats shrink in width now The crew was very friendly and professional ( 100%). Food was good not great, breakfast was bad, a dry slice of bread would have been better. Facilities clean.

I think they overbooked Frankfurt to New York and bumped me off. This changed my return travel I arrived home about 4 hours late. Almost 24 total travel time Totally unacceptable Would not travel with United

Flight was delayed over one hour and I had to pay to select my seat, even though my booking supposedly had free selection (I paid extra for this at time of booking)
