This flight leg was fantastic - super comfortable and a great selection of things to watch on the TV. Staff were excellent, really above and beyond.

Not enough veg food available for passengers. I actually did not get the veg food and was told it was over, and I starved the entire flight duration.
Lately I like the planes have been exceptionally filthy. There’s lines of dust and dirt all across the ceiling in the vents, and the cracks in between the seats are literally full of food. It’s definitely not the quality of service that I was used to with United. I’m also very disappointed with the Wi-Fi! All I wanna do is knock out a few work jobs while I’m trapped in my seat And it spools so bad. They did provide me with a refund, but the process of getting that refund is so complicated. It’s unfortunate.
Excellent flight. Smooth, efficient boarding. Quick flight. Arrived early at STL.
The LH flight was great except for the delay at boarding. It should be announced well in tme.
Could have said yes to a glass of wine 🍷 instead of saying we'll come around in a couple of hours
Inoperable monitor left no entert for 9 hours. Crew was not helpful Food was awful.
The food and sitting need improvements. They were extremely bad.. If you choose to recline, there is no room for the passenger behind you. This is one of the worst sitting arrangements that I ever experience. The aircraft was not properly clean before boarding.
Had one staff that was not pleasant. Seems they are stressed with too many people to care for.
Ok. Get a different kosher caterer. The food was odd.
Booked seats (paid extra) online and found they didn’t exist on the flight. We were then separated from the rest of our party. Given seats in the very back of the plane. We will not fly Discover or Lufthansa again. We will not book flights or travel through Kayak again!
Had a few open seats and could use it for a great rest ful journey
Airline food is airline food, but the plane was wonderful and the seating comfort outstanding. One of my best flights in quite a while.
Smooth flight with enough time for connection. Ran out of meal options. In-flight and gate staff were friendly and helpful. Good service overall.
The seat space seemed small especially when the person ahead reclined but other than that, very good.
Everything went well. I will fly with Lufthansa again. And use Kayak whenever I book flights
Bought a seat in a flight that got changed out so ended up paying for a seat I would have had if I hadn't paid.
Food was poor quality and the screens for entertainment didn’t work properly
United lost my travel information and canceled my original flight. I had a seat assignment but was refused the booking. I had to prove that I went to Germany on United Very concerned about security that no one recorded my passport from Cleveland to NY and NY to Frankfurt I arrived at home at 12:30am on Saturday instead of 8pm I expect a full refund from United Please provide information to assure compensation
I paid for extra legroom which made the long flight very comfortable. Food was very tasty, they fed us 2 meals plus a cookie snack and extra liquids. Checked luggage is expensive.
