Outstanding service, efficient & friendly crew, flight was safe, comfortable & on time

Outstanding service, great food, friendly & efficient crew, safe & comfortable flight

Staff were not attentive, wifi did not work, cut my head in the bathroom due to the position of the soap on the sink, had blood running down my face, told staff, they had no expression no sympathy, didn't even say "sorry", they said "oh we will have a look at that" about 10 mins later the purser brought me a bandaid, still no sorry.... Shocking

The crew was great. Very friendly and responsive. The plane was old, small and tight. We ran out of overhead space and I had to check. Middle seat was particularly tight.

The flight was delayed from take off because only one runway was operational in San Francisco.

Several missed and almost missed connections. It felt like everything was being patched together last minute without enough resources and it ended up being an extremely stressful experience that basically ruined our weekend on the west coast. What a waste.

Dinner was good, but the breakfast served in the morning was horrible.

Packed in plane small uncomfortable seats elbow to elbow nobody wants to be in that situation for the money they paid

Checking in united could not figure out my star alliance gold. Baggage did not get marked priority and didn't receive boarding passes. When got to SFO lounge personal fixed everything Immediately

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..

Service was excellent. Flight was only about half full, which meant we had tons of room to stretch out. Boarding area was nice and well organized, flight attendants were super friendly and attentive and we loved the 3 snacks!

My flight was cancelled, but it was not Kayak's fault. Kayak did require me to pay for the ticket twice to two different venders who paid Lufthansa. Kayak/Lufthansa owes me for the first booking I made first was fraudulent on the part of the subcontracting ticket seller. There will be litigation over this issue under the current passenger protection laws.

Original Lufthansa flights were canceled and the alternative route that was offered required cab transfer in New York from JFK to Newark at my own expense. Who can refund these $218?

flight was half full, plenty of empty seats, was able to lie down across 4 seats, food was good, arrived on time

flight was packed, had to check my carryon bag, tiny snack bag offered, but we arrived on time and thats what counts

Was never allowed on and not refunded the full amount of the ticket plus charged a $300 processing fee.

Terrible. Our flight was completely cancelled with no options to rebook until 4 days later.

Generally good. Not their fault but the design of the Boeing 747 had seating supports directly in line with my legs. So my legs always had to straddle this support which caused body misallignment. Such poor design from Boeing. There was no USB port for me to charge my phone. The screen touch control was very poor.

Patrick and the whole crew were amazing! Hope to have this team for all my European trips.

Smooth flight with enough time for connection. Ran out of meal options. In-flight and gate staff were friendly and helpful. Good service overall.
