Food was terrible Not many options Stewards dont care Delay

Our original business class flight was cancelled so we not only downgraded but we were also spread out across the plane not sitting together in separate middle seats. My poor kids were scared and couldn’t see me on the flight and the crew wasn’t sensitive to the situation and what the airlines did to us. Very dissatisfied with United airlines.

Hated every minute of it. This flight should have only taken 1.5hrs but was delayed over 10hours. Now I am being told I cannot be compensated or refunded my ticket price or extra leg room, which I purchased but did not receive, because the airline is throwing the blame on the 3rd party I purchased tickets through and 3rd party putting the blame on airline. No one wants to help. They received their money and that's all they care about. Im going on 3 days of still trying to get to my final destination, had to cancel car rental, car insurance and hotel. Currently staying in airport until hotels open up. Thank you Lufthansa, Kayak, Underpricer and United for making this trip the worst ever.

the flight from Tampa departed with a delay. The food on board was poor, usually on international airlines alcoholic beverages are offered free of charge , but here it was for a fee, the cutlery was wooden, there were no hot drinks (tea, coffee). Unfortunately, I didn't take pictures of the portions of food, but it wouldn't have been enough for a child either.And in the future, I will try not to use the services of this airline

Good dinner and nice plane.Smootz flight. Breakfast had no sweet option. Seats hardly reclined.

Flight from CLT to DUS via MUC ticketed by United Airlines and operated by Lufthansa. 2nd leg of flight from MUC to DUS was cancelled and no notification provided. At check in , Lufthansa agents at airport were unable to locate record and wanted us to contact United Airlines directly.

Boarding went well, staff was friendly. Food was not goods at all. I had ordered vegan meal. The seat I picked didn’t have storage area in the front and so had to put my small back pack at the top.my flight to Bangalore from Munich, the tv was broken so I got complimentary wifi which never worked. Food there too wasn’t good. I had paid extra for the seats. The only good thing is that the fact we have a flight direct from Charlotte to Bangalore with one stop in Munich!

The flight and crew were fine. The entertainment- the sound was so bad through the headphones I could barely understand it and it was a show I had seen before. The food might have been fine but having to have an account with united in order to access the app in order to pay for the food was rage inducing. I had entered my credit card info at home and logged in as guest but that wouldn’t allow the “wallet” tab to open in the app. And then the wifi was so bad that it took about 45 minutes to fully log in and get all the info working at which time I missed the food. You shouldn’t have to give your address, email and phone number in order to get a hamburger.

It was a great flight, great crew, excellent service, fantastic brand new place, overall 10+ on the experience! Thank you.

I really enjoyed the staff and crew! Very positive and happy people! Made the experience easier! The entertainment was a bit lack luster. Better movie options as well as equipment that works smoother could be nice. My ear buds from the airline didn’t work and my tv screen had a terrible delay that made it hard to search for things to watch. Also the selections were very limited.

Both flights were late for what appeared to be the airline’s not having the planes ready. Arrived over 6 hours late.

It was a busy flight and all the crew were very helpful and gracious

Seats were not the most comfortable and food options weren’t great but overall but everything else was excellent

Check-in very easy and smooth. Plane and crew were nice. Seat open next to me created more space. Food was fair but plentiful. Lots of movies and I was able to sleep some on the way to Munich. Very tight connection, about an hour. Fast through passport control and a bit of a walk to last G terminal gate but I made my connection to Palma. Unfortunately, my luggage did not make it. It is now almost 24 hours since I anded and still NO luggage. I know it landed last night on another flight. Local delivery should be today to my hotel in Palma but nothing yet. I asked about the tight connection when I checked in and was assured they would get my luggage to the connecting flight. Very disappointing it missed my flight but more disappointing that it has taken so long to arrive. Failure on the airlines and service to get my luggage to date.

I wish the flight attendant was a little bit kinder

The food wasn’t great and it would be nice if the airlines showed documentaries about the countries we are flying into.

Disappointed everytime. The app doesn't load the boarding passes. They have lots of agent that seem to be busy doing nothing with a long line waiting to get paper boarding passes. Food choices are poor. Entertainment is less than entertaining.

Horrible experience. Nothing to give to kids to keep them entertained.

I think I have bruises on my kneecaps. Do the seats have to be so close together these days? And if they are so close they really shouldn’t recline. I think when the gentleman in front of me reclined, the back of his head was on my chin. That being said the crew were always caring and polite, and the flight was on time and very safe. So I’m grateful for that.

I dropped my wallet under my seat on this flight with all of my money and credit card. I requested to be able to go back and retrieve it but Lufthansa denied my request. I went to the Customer Services and they called Lost and Found but I was told nothing found would be turned in until around 12:00pm. My next flight was leaving so I was unable to check to see if my wallet was turned in. I will never fly with Lufthansa again.

Not connecting flights. Missed my flight from Dublin to Liverpool because I arrived at Dublin one hour too late. For this mistake, they offered me a flight from Dublin to Manchester. Thats great and all, but I waste time and money to commute to Liverpool. Be sure to check the time of your connecting flights, because they sure don’t when they sell it to you

Excellent! Great flight attendants, good food (in business class, at least), very comfortable. Touchscreen and remote wasn’t great.

In economy and food was ok, but with limited leg space (and I was in a 2 seat configuration) it was difficult to eat with a tiny seat tray. I spilt wine on my trousers. First time on British Air (I usually fly Turkish Air) and in a 777. Heathrow was pleasant but changing terminals awkward.

Starting with the flight Cairo to London the plain was so poor no entertainment at all uncomfortable seats although it’s 5 hours long,then an American airline plain took me from London to Miami it was a bad experience the crew most of flight time not available and they asked us to help our selves for any snacks if we need. From Miami to London actually was perfect flight with a huge plain and perfect crew but from London to Cairo was horrible plain with stiff fixed seats not movable no entertainment or wi fi very poor Menu which is unacceptable for a business class

I've done hundreds of flights in my life, and this flight was one of the best I've ever taken, From beginning to end, everything went smoothly, professionally, and with a smile and friendly attitude from all employees I interacted with. The food was delicious (and free), as were the drinks. There was just a genial and effective way in the way that British Airways organized the flight -that reminded of days in the 70's, 80's, and 90's, when flying was a fun, and exciting adventure. I enjoyed and had confidence in the abilities of the flight crew, I'll be flying British Airways several more times this summer. Thank you so much for the great experience! Cheryl Olso

My baggage did not arrived with me. Took 3 days to get it after so may calls and follow up

Terrible! I missed my flight to my final destination and British airlines and American Airlines keep pointing fingers on each other’s. Nobody wants to take responsibility

Terrible. Flight was 3 hours delayed and I missed my other flight to my final destination

Overall, terrific service, accommodations, and experience. Only reason comfort was rated lower was because it was difficult to keep a comfortable sleeping position for the overnight flight, but I also had an economy seat.

Not sure if the crew were experiencing something unknown to me,but the service of passing water was non-existent.In addition,please take consideration when providing yogurt as alternative for breakfast as some of us, could be lactose intolerant.. thanks
