Surprisingly the coffee was pretty good and they had a gluten free bar handy!

Gate agents call groups one and two and give about 3-5 minutes for each group to board, then the call groups three and four together and it causes a bottleneck in the line. Give each group 3-5 minutes to board before calling the next group.

We sat at the gate for over 30 minutes, with no indication as to why

I didn't really interact with any of the crew since we had a bumpy ride and no refreshments were distributed.

It was delayed over an hour and a lot of announcements disrupting movie.

I didn't use the onboard amenities, so it is difficult to comment on those services. Otherwise, the flight from Nashville to Toronto was quite crowded, but the boarding process and the flight itself were perfectly fine.

Seats were old and very uncomfortable. Coach seating is way too tight

WiFi was a major problem and if it does not work on a 4 hour flight then that lowers the overall experience

One of the best crews and best flights I’ve ever had! Really great experience

The bus ride from the terminal to board the plane is uncomfortable and stressful when making a connection.

United did nit provide any updated on flight crew not bein available until boarding time started. It was bad. Itws alate night flight and there no proactive communication and iha d an important meeting that i missed due to thus

From the boarding crew to the FAs was such a good team. All with smiles and positive energy. The pilots made an announcement of us waiting on some passengers who were late landing and I didn’t hear one person feel like it was an inconvenience which was wonderful. Massive kudos to all that worked that flight. Everyone was united. 😊💙

Smooth flight, easy boarding process. Made up time in the air with initial delay due to weather pass through

Usual wait for over a half hour for a gate at Ohare. They tell you you'll get there early then sit on the plane and wait almost an hour

Plane congestion resulted in a 1 hr wait from landing to arrival at the gate. This was in addition to also experiencing extreme delays on my incoming flight.

Delayed too much. 1.5 hrs in the airport and another 1 hr in the runway. Got too late in the night. There was no proper food available.

Sitting on the runway after we land for almost two hours! Not sure if we should blame United or Just Dumpy Vance.

Why wasn't this flight departure scheduled eith another crew so that it could leave on time? When we arrived in Denver we had so little time between flights we had run to the connecting flight. We should received some credit for the inconvenience.

Please please take consideration when setting cabin temperature. The vents were not functional and it was over 70 degrees in the cabin during the winter months when most people are used to much cooler indoor temperatures. I was down to my white t-shirt and the sweat pants I wore from Auckland to San Francisco and was sweating profusely and there was NO VENT!

My flight was 3 hours late, which caused me to miss my connection in Denver. Further, this connecting flight was then Later canceled. This required me to stay another night an hour and a half away, and rent the rental car for an additional Night. I am still waiting for United Airlines to reimburse me for the inconvenience and Expense of having to extend my rental Car for An additional Day.
