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..
