I was exhausted from a long day. The flight was smooth. The first flight during my 3 week travel that took off on time.

Boarded early; and arrived home 40 mins early. After a long flight, it’s nice to be back home early. These flights have no amenities; no snacks. So need to bring your own

As I wrote earlier, poor planning and/or communication. At least twice, we were told that we would be boarding in less than ten minutes, only to have the flight again delayed at least another hour.

It was a red-eye, but the flight felt surprisingly quick. The seats were very comfortable, and that made resting much easier. I also want to thank the gentleman seated next to me, who graciously moved so my mom could sit beside me. We slept almost the entire way. The cabin crew was respectful in not disturbing us, while also being courteous and professional throughout. Thank you, United.

Terrible. No customer service, no food, no drinks on a 6 hour premier economy booking.

left on time, reasonable boarding process arrived early luggage came out quickly

The LH flight was great except for the delay at boarding. It should be announced well in tme.

Compared with other carriers business class for an overnight was not worth the extra expense.

Nothing wrong with the flight itself. But due to 2+ hrs waiting in immigration and the additional security checkup in O’hare, I nearly missed the flight.

Another late flight from United. We never got the exact reason why. When we got on the plane, the staff seemed to spend a very long time just milling around in the front of the plane. I also never figured out why the door to the cockpit was open for so long prior to leaving. All in all just a poor performance again from United. There is a reason we did not choose United for the international legs of this recent trip, overall dissatisfaction.
