Everything was on time Will use united again for sure

Plane outlets in my row not working to charge phone. Staff response was, well it should be. Plug into seed for volume not working well. Had to find the sweet spot for plug in or it would shut off and on.

Fine not above and beyond as I had a connection that was delayed due to maintenance

The power at the seat didn't work and the seat itself was difficult to adjust - this was a business class seat. Flight attendant gave me miles to compensate. The attendant was very professional and on top of his game the entire flight.

I upgraded my seat and was promised it would be next to the emergency door for extra leg room and they said it was premium plus but it was at the back of the plane...same thing happened from Newark to Dubai

Everything except the food and entertainment. It was a great experience though

Bad food, bad service, cold cabin with no additional blankets when asked for (they told me they don’t provide additional blankets). I’m a frequent traveler and this is one of the worst companies I traveled with (by the way I thought that I booked my ticket with Lufthansa but I didn’t see that the flights were handled by United).

United Airlines is my preferred airlines and I am thankful for Gary who also help support me on the phone to switch my flight literally last min.

Not being stranded in Chicago for her airport to 11:30 tomorrow morning the 3rd

the whole trip was smooth, and as comfortable as flying is these days. flight crew was friendly and very courteous and helpful.
