The flight to America was freezing. The overnight flight back to the UK was boiling hot and the cabin stank of toilet or occasionally perfume, even though I was several rows back from either bathroom. Food was tiny portions. Two small pieces of tough and dry beef in random gravy with pretend mashed potato raking up most of it. Very little veg. Salad was ok. Wooden cutlery broke within minutes of using. Lots of old films for entertainment. Some new ones. Generally a bit rubbish.

Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.

It was terribly delayed with zero support from united airlines. I reached at 1 am in the night. They did not provide any option to change the flights.

Flight was delayed 14 hours due to DC air show and weather. Missed connection to MUC.

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

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

Miserable. They moved my seat, but canceled the next leg of my flight. I resolved the issue at my transfer, but that resulted in lost luggage that has taken days off my schedule with no resolution. Worse, they fail to interface effectively with Lufthansa, forcing me to bounce between two equally useless help desks. The apps are unable to handle the situation, the bag dropped off the tracker, and while the call centers are polite, they do not provide written information to assist with cross-airline communication.

The only downside was my cell phone charger wouldn’t work in the charging port but everyone else’s would work in them all. My cell phone cable works fine in my hotel room in Frankfurt.

Smoothly flight, pleasant flight attendants. I wish there were better food choices.

A three (3) hour flight should have meal service in First Class, not just potato chips!
