ok, butt flght was delyed for 2,5h from Frankfurt, and next Flight to Columbuse same

Very kind Lufthansa agent somehow gave us all no charge extra business class seats and helped us get home rested and happy.

United was excellent. We had very good experience flying the carrier. Certainly. We will opt to fly them for sure. Lufthansa is out.

There was a little turbulence taking off and landing but mostly it was too late for me to make my connecting flight to Greensboro. Everything else was excellent.

The seats were very nice in premium economy. The service was good. The flight was slightly bumpy. Would have appreciated more updates from the pilots.

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.

Meals were poor and service rendered on return flight was mediocre as compared to the flight we took to Germany earlier where the attendants were more attentive, energetic, and mindful of passengers' needs. Thumbs up to crew of UA 58. Thumbs down to UA 59..

The crew was generally professional. Though one of the crew members seemed to be easily annoyed, the others were fine and helpful. The green olives and almonds snack was really good. A great idea, and nice balance of tastes.

Would've been great if Lufthansa union cockpit pilots didn't strike for 2 days and caused a chaos to my returning plans to USA, and then after rebooking a flight 2 days later tge plane departed 35 min later. So I did not have a good experience.

It was okay, the food was good, but after the landing there was not enough time for luggage and security to catch a connection. It was crowded on board.

That was the last time I booked Kayak. The connecting flight got canceled and the trouble shooting terrible. Next times, I will book the airlines directly. Good bye

I want to highlight the crew members and their excellent work and professionalism. They work hard to make a long trip the most comfortable as possible, the food and drinks they offer are pretty good. And they are always asking if you need something else. I have had experiences with other airlines where you have to basically beg for a bottle of water. This is not the case. Highly recommended!!!

Way too crampled. Charge more and put in less seats.

the blanket was great and pillow helped. really need a toothpick packed with meals

This was the worst flight of my life. Economy seat directly behind a premium economy seat with extra recline meant I have about 6 inches between my face and their chair. My seat would not recline at all. I couldn't even use my laptop on the tray table because I had so little room. I was in a casket basically for 10 hours. Completely unacceptable.

Horrible airport ever. We stood in the security check line for more than an hour. It was past boarding time and we were still waiting in line for the security check. With 2 children and a medically ill person we had a very stressful transit.

We missed our connecting flight in Frankfurt do to security and all hell ensued then.we got rebooked to Washington got there round 10 am ish didn't find out till 630 we were rerouted to United!! Then we started getting updates

Too tight connection. Lufthansa staff pulled 12 of us out of passport control that had tight connections and took us about 1/3 mile AWAY from our gates and put us in another slow, long line. Needless to say all of us missed our flights and the Customer “Service” staff was rude and not helpful at all. Was rebooked from a direct flight to one w a 6hr layover. Asked about an other option that was on my app and was told to book it myself online (which would be $300 extra pp!!). Got rebooked again w a tight connection which was also missed. Rebooked into middle seats that didn’t recline for 9 hr flight!! No compensation (and we paid for seats!) Ended up taking 26hrs to get home from Europe to North Carolina! No longer a fan of Lufthansa—2nd time having these kind of issues w them!

The food on this flight was better than what we had getting to Rome. The flight was comfortable and the staff was great. One of the staff members was a stickler about the blankets in the aisle, which I get, but still. Overall, great flight and will fly with them again!

The legroom was lacking and the entertainment system lacked adequate selection of older films. Modern films are generally not very good.
