I liked nothing. An extremely uncomfortable flight, staff were rude, no ice for my drink. 4 hours of misery

I liked nothing. An extremely uncomfortable flight, staff were rude, no ice for my drink. 4 hours of misery

We had a delay. That made me feel anxious because I arrived out of time

Good value for the money. Good leg room. Take off and landing very good.

Delayed delayed delayed and then cancelled very late not allowing for too much time to find a room for the night

expedite passengers through passport control when the airport authorities are processing inefficiently.

My flight was delayed 1 hour. My Mood was not great

Great flight and crew but let down yet again by the disaster that is Birmingham Airport

Crowded, little leg room, little lateral room. Hour late, then all funnelled into a small room with a couple of bench seats for 150 people. Most sitting on the floor or standing for 30 mins before chaotic boarding.

1. Too long on board without air conditioning. 2. Very very long-tiring walk to exit gate.

You can only check in maximum 2 hours before your flight. But it’s not written anywhere on your ticket or your boarding pass or in any of your emails. The only sign is at the beginning of a huge snake queue on the barrier which is easily blocked by people. So you queue for half an hour only to be turned back. Plus on the flight we paid for priority which included two carry on bags in addition to our backpacks plus I had a letter from Ryanair for my CPAP machine to be allowed as free carry on as well. As it happened, we only had one carry on and the CPAP and two backpacks and the agent insisted I shove my CPAP under my seat which I refused as it wouldn’t fit without jamming it. They had oversold priority (or didn’t check bags) and there was an enormous fuss about overhead storage. Poorly managed and the inflight ordering service didn’t work. It was awful. I will never fly them again. And before you say it was cheap, it was most certainly not. So Ryanair can kiss my business goodbye.

Liked - efficiency of boarding with 2 jetways. Checkin was with kiosks with helpful and plentiful workers to help with the process. Munich airport security was very automated, efficient and effective. Free wine and beer! Cons - food was only okay in economy class. Plane bathrooms could have been cleaner.

Disappointing. Too many let-downs, in delays and communication, by both Lufthansa and Discover to put in an email. I am resigned to the fact that this is what I should expect from all airlines. Unfortunately.

Crew were professionals. However, the plane seats are too small -essentially there is no space to move around which for so many hours is almost inhuman but certainly unacceptable. Same with the bad quality of food and the fact that you need to purchase Wi-Fi

Sorry, I’m not a fan of United. The seats are just too cramped and uncomfortable if you are traveling very far.

I think it was a United A380 plane. The trip from Munich to Denver was about 12 hours and the preferred economy seat I paid $75 for was very cramped. The crew was nice but I was so uncomfortable and getting up to walk around didn’t really help. My legs were swollen for 4 days afterward. I would think on such a long trip the seats would have more room. I would have gone 1st class but it was 3-4 times more expensive. I won’t fly anywhere far away again. My last experience with Lufthansa was great to Italy and back, but this time I could swear everything was United and not good.

Boarding was total chaos. They didn’t know what they were doing and taking bus to the airplane is like going back in time. The food is bad, portions are very small and we don’t get simple paper napkins! Is it really that bad?

Great crew dealing with the most unprepared family with a million kids and zero sense.

We were disappointed not to be able to buy out preferred seat from date of my original booking, which was about 40 days before the trip. When we arrived in Hannover on the Oct 10 I tried every day and the weed site said I have to wait until ck in, did that and still was not able to. Get to the airport and out seats were separate from each other. The crew was able to get seats together, was not the most comfortable. Don’t understand why this happened.

Actual flight was smooth but we were delayed 70 minutes. Were promised to make it up to us but were given no refreshments

I had handicap and pre board due to a recent broken arm, was made to find my own help placing carry on baggage in the storage above. My tv and entertainment unit did not work correctly, requested help and it took 30 minutes to get help, she did not fix it or come back to see if it was fixed. I went to her a second time and she did another reset, still did not fix.
