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

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

Having to up charge for a seat assignment is not good. Delta can do better

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.

awesome team work seen since on board till off plane in my destination. thanks you so much.

Job well done, being treated for good and helping a lot . thanks you so much till will meet against.

Very disappointing that on an international business class flight they would not give me access to the lounge in Boston. They said it was because it was a codeshare flight. International business class should include lounge access regardless of codeshare.

They did not have free WIFI and I was not okay with that!

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.

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.
