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 transfer was awful, everyone was running to catch the flight, there was no information on the process. We git to the gate and the boarding was late and had to stay in different lines but there was no guidance. The flight was late and uncomfortable, probably one of the worst flights I have been on. The luggage was sent to a different terminal and still did not make back to us.

The awful part was the customs delays at ZRH. The good part is the flight was delayed long enough to accommodate. The flight itself was fairly comfortable.

It was on time and we arrived safely—that's a good thing. Other than that, my son's seatback storage pocket was ripped and couldn't hold anything, and his footrest was stuck so he couldn't use it. You pay extra money for allegedly more comfort, but the plane was old and the seats were broken. No drinks were offered in the beginning like in other premium economy settings, no hot towels. It was really basic and nothing more than economy other than three times the price. Very disapointed. My food tray was VERY dirty—I couldn't even eat anything after seeing that. I will try to avoid SWISS in my future travels

Slow boarding, late departure and arrival. Very good crew and free messaging over WiFi but outdated electronics and seats

Overall good solid airline but got “burn” with my check in the “free” laugage that weighed 8 kg.

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

The crew and service was excellent. The food and entertainment were very good but not excellent.

Entertainment sounds were not good. Otherwise everything else was good.

The layover should have been one where I could have actually reached my connecting flight in time if all flights were in time.

Awful!!!. I do not recommend United. The flight staff are unhappy and don't attempt to make the passengers feel comfortable or welcome. The food is not edible, and the seats are miserable. My expensive luggage was destroyed, and the ticket prices are too much for the experience.

On time, easy boarding. Anytime you sit in an economy seat, it’s uncomfortable. New plane and the bathrooms were in the galley at the back of the plane which seemed odd.

Did not like the check in guy quibbling over a couple pounds at the luggage weigh in

Just having a little bit more legroom would've been nice.

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

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

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

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!

I had always heard bad reviews about United Airlines so I have always avoided them when traveling. Little did I know that when I booked my flight with Swiss Air they would swap it to a United Airlines flight. The change was made only days before my departure leaving me no option to cancel or get a refund. I hoped for the best but experienced the worst. I paid for 2 seats for my daughter (13)and i to travel together. Both times leaving from home airport and returning from vacation, they sat us apart from each other: different seats and rows far away where we couldn'teven see or waive at each other. There was no option to change because by the time you're allowed to check-in the only seats available next to each other cost nearly $200 each. I stomached the extra cost from the first flight hoping the return flight would be better. No chance! The return flight was worse. I was sandwiched for an 9 hour flight between 2 stangers while my 13 year old sat 5 rows down . Just horrible experience. NEVER AGAIN will i fly Swiss Air or United Airlines ! So disappointing.

The entertainment system was not working, they tried restarting it couple of times but it did not fix it. We were told to contact Lufthansa costumer service after the flight for some kind of reimbursement. When costumer service was contacted I was told no reimbursement for entertainment system malfunction per policy.

I was never able to use this flight. I booked my flight through KAYAK, using cheapfaresflights, and the agency did not book the ticket correctly. When I went to check in for my flight in Rome, my details had changed. My name was incorrect , and the itinerary was not what I had paid for. I was unable to board the flight and I had to purchase a second ticket at considerable expense. Unfortunately, no one at KAYAK or Cheapfaresflights was able to help me. They both shifted the blame on United Airlines, United Airlines was able to provide me a full detail that the error occurred on the travel agencies side. I consider this fraud and will pursue it further.

Cancelled 90 min AFTER Departure! We had to deplane and wait another hour plus for the flight to be shown as cancelled for the customer service team. There were many many angry customers.

Bulkhead seats should not be an extra charge. They are extremely uncomfortable. And we missed our connecting flight due to slow luggage retreaval.

Lufthansa flight LH04414 from Munich to Washington DC, was fine. Efficient and safe!

Bumpy ride, not Lufthansa‘s fault. Crew managed a situation over a back rest to far down well. It was two iles behind me. The person putting the seat down, against the other person’s knees, was quite rude and belligerent and needed to be told in a no nonsense matter to stopp. Male flight attendant did good job.

Had a few open seats and could use it for a great rest ful journey

It was very good. Service was friendly and efficient, and food was good.

We left 1.5 hours late therefore missing my connection. The airline didn’t give vouchers.

Food could have something without dairy, I couldn't eat anything. Tv for both seats was malfunctioning. They have one bottle of ginger ale for entire plane.... and I paid extra for these seats...very disappointed
