Perfect flight. Smooth flight. Arrived 20 minutes early at destination. Excellent service.

Flight was delayed 8 times. We were sitting at the airport for 14 hours. We got 2 hours of sleep (if that) on what was not meant to be a red-eye.

Plane boarded early a quickly, was mostly full. We left close to on time. And landed early.

Flight was timely, relatively comfortable, with decent entertainment and food served. Only problem encountered was with the free messaging which I highly appreciate, but it did not work from iphone to non-iphones.

This flight was perfect. No complaints and only the highest regard for the crew and ground staff and how they executed perfectly. I fly a lot with United and would request predictability and transparency in their operations instead of last minute changes.

Survey sent before we actually left. Delay after delay. Now a crew problem.

I love flying with United. Unfortunately, I flew on an older plane with minimal upgraded technology (no Bluetooth functionality or handy charging ports). Otherwise, the flight was great and even arrived early.

They changed my seats after I checked in and I was stressed from the time I saw that information until just before boarding, when the gate attendant fixed it, but it shouldn't have happened. And if it couldn't be prevented, then the people on the phone I spoke with should have done something to help, which they did not, nor did they offer me compensation, just meaningless apologies.

Smooth flight, especially take off and landing, and great crew on board. Really loved the stroopwaffles!

Deplaning was delayed because of Jetbridge equipment issues in MKE, causing an issue on an otherwise great flight.
