It’s a 3 hour flight with no entertainment and no WiFi due to Delta using old planes on this route and food is cold. Today we were told no potable water on the flight to even make coffee or tea. Ridiculous service in this direct route for business travelers and non business travelers

The crew was excellent but the entertainment did not work. The 3mm jack for the headphones was faulty and no sound was available for entertainment.

The number of interim flight delays has been higher than I can remember in my history of travel making any connection a mystery as to whether you will actually make it.

THI IS THE 3RD CONSECUTIVE FLIGHT FROM ORD TO MSP THAT HAS BEEN DELAYED 2+ HOURS. CRAZY

Sat in the plane at the gate in SLC for 2+ hours before take off, getting me home nearly 3 hours later than planned.

I was impressed with how quickly the baggage transfers were made.

The Airline Attendant found us in flight and moved us to seats in the front of economy due to the short time we would have to make our connecting flight. We really appreciated it.

For some reason, there was very little volume on the cabin announcements. You could not hear what the pilot or crew were saying.

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

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!

Flight was on time, clean, etc. Despite connecting to your wi fi I was unable to use your app to watch entertainment.

Awful!!!. I do not recommend United. The flight staff are unhappy and don't attempt to make the passengers feel comfortable or welcome. The food is not edible, and the seats are miserable. My expensive luggage was destroyed, and the ticket prices are too much for the experience.

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.
