Crew was great. Seats are cramped and uncomfortable and I’m a small person.

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

Awful. Delay after delay. And then again on the tarmac.

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

Food was not Good Nuts came very wet & not tasting Good Main course I asked for Steak they got me Chicken because they don’t have more !!!!

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.

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

Very comfortable plane. The food was very good (for airplane food). The crew was great

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
