The crew were unprofessional with a racist element. I was physically abused as well from one of the crew members

Crew is not the cheerful type. very slow meal service (this is their style as have flown this many times)

Legroom not all it could be, especially when the seat in front is reclined. Otherwise it was good, food and beverage were nice.

This fight left ahead of time which meant it arrived early which was great. Staff were very professional, but as with all these Short hop Flights the food was a disappointing snack There was no entertainment on this flight, but I did not expect any

I flew premium economy and this was a good option. Although the seats didn’t recline much, I was able to get some sleep with my head propped against the window. The food was good and the entertainment was wonderful The staff were very attentive and professional

Seats were nice and comfy. Crew was polite and attentive. Business class is awesome and worth the money.

Overall a very pleasant flight. No significant issues on either flight. Amsterdam airport is very convenient for connecting

It was operated by Delta. Boarding took a long time. How difficult can it be? Overall decent trip. Liked the Salt Lake City airport. Better option than Chicago for transfers.

We left one hour late because of technical difficulties. The economy comfort seats are great for the price. The crew was mediocre, they do not provide a pleasant experience, they just deliver food and drinks and give orders, not very amicable, no service and hospitality focus.

Overall a good experience. We were disappointed when we had to check our carry on due to the plane being full. KLM hadn’t notified us and we had valuable items in the carry on but they still made us check it. Some of the food was great and some was mediocre. Crew is really kind and funny.

Horrible I am at almost 2,000,000 miles on United. This was probably the worst flight ever. An hour and a half before takeoff I get a message that they’re changing the plane and I no longer have a seat in Polaris business Supposedly, there was a problem with the plane, but then there was no other plane Finally, they decided to bring a plane from Newark to Washington Dulles Of course the original flight was at 10:45 PM so by the time the plane got there it was 12:30 AM. It had not been cleaned. It had not been catered. They don’t really have people available to do those things when it’s not pre-programmed at 1 o’clock in the morning. The crew had to be changed And the new plane held 28 fewer people than the scheduled plane There is no way you can hate United Airlines enough The people at the gate were actually just fine, but it was management who was completely useless And did they send extra help to the people at the gate? Did they send supervisors? Of course not. Just don’t take United find somebody else or buy a boat

Flight attendants were great. Food mediocre. Bamboo utensils not Great especially if you have to cut something. Seating a bit crowded.

The crew was the worst ive ever had in my life flying with United Airlines, letting another person move my bag without asking and then the staff saying would the floor be better after I kept begging saying dont move my bag it has fragile things inside. This incident truly makes me they favor other customers more and I dont want to worry about being on the tail end. Especially if they dont listen any input, no care for what I asked but accommodated those who are reckless and disturb others more...

Our flight was delayed 2.5 hours from Lisbon to DC so we missed our connection to Seattle that would have arrived at about 9 PM. The agent initially said we had to stay overnight in DC and there were no other options to put us on to get us to Seattle. While on board I discovered a flight via American he could have put us in but by the time we arrived in DC that was sold out. We were then put on a flight to San Francisco that was also delayed then arrived in San Francisco and our flight to Seattle was also delayed so we ended up not arriving until 2:15 am. Our son could not pick us up so we ended up having to pay over $100 to Uber home. This is the second trip with United that the flight has been delayed causing us to miss an evening in Las Vegas and we were given nothing.

MY FAMILY'S LUGGAGE WAS LOST FROM ROME TO BARI. I WAS THE ONLY ONE THAT RECEIVED MY LUGGAGE FROM ROME TO BARI. AFTER DEPLANING IN BARI, WE WASTED A LOT OF TIME AT BAG CLAIMS LOST AND FOUND REPORTING THE CLAIM AND PLEADING FOR THE BAGS TO BE DELIVERED THE NEXT DAY. WE WERE TOLD THAT IT TAKES 3 DAYS MINIMUM TO DELIVER. MY DAUGHTER AND MY GIRLFRIEND NEEDED THEIR PERSONAL THINGS AND WE WERE STAYING 3 HOURS AWAY FROM THE BARI AIRPORT. WE HAD TO DRIVE 3 HOURS TO THE AIRPORT TO COLLECT OUR LOST LUGGAGE THE NEXT DAY. WE ARE NOT HAPPY WITH THE EXPERIENCE

There were no facilities in the middle of the aircraft and premium economy was not allowed to use the business class facilities, and had to share the only two toilets at the back with economy. The upgrade to Premium was definitely not worth it

Our flight to Rome, Italy was cancelled the day of and we were never informed. We only found out because I was trying to get into my husbands account and called to get his account number. Had to pay more for worse seating on another airline.

The economy seat was much less comfortable for an international flight in terms of recline and moving space when food tray is expanded. Per entertainment, it would be amazing if I could connect my Bluetooth headset or ear phones to the entertainment screen. Or provide in-flight wifi to connect directly from my own device.

We were a little disappointed to not be able to complete check in online without uploading pics of passports. Also we have KTN's and they weren't on our boarding passes when we got to security. Had to trek back to counter to have them fix.

Excellent service in Polaris class IAD to ZRH. Arrived rested and well fed after the overnight flight.
