Great! The plane was decently sized and comfortable. The staff was nice and there was great in flight entertainment

Last minute gate change nearly caused us to miss our flight. Change was not announced or displayed in the main board at the old gate. Terrible communication. When we landed we had to wait 20 minutes because there was another plane at the assigned gate. Not the crew’s fault, but adding 20 minutes to a 45 minute flight sucked.

delay several times and wait extra long to board. no entertainment service because there are problem for some rows. always encounter some delays for the last flight of the day.

The flight was delayed instead of leaving at 11 it left at 12.20

The flight experience was very good! Especially the United Club!

I was not able to buy food in the flight. They refer to include your Credit card in the APP, and if you are not from USA (i have a credit card form Canada) it is not possible

The flight from Ottawa to Chicago took a lot longer due to DC in Ottawa. We got to Chicago and went to our gate to catch our flight. We only had nine minutes I found that very stressful.

Good boarding. Crew started quick with drinks and food. They came around several times for trash which I really liked. Other than turbulence due to storms in the area, flight was great.

The control panel for the seat back screen did not work at all after takeoff.

Paid WiFi was only available for a few minutes. Avoid at all costs.
