The plane was a rather tired 737-800, with old style small luggage bins. Poor air flow. USB charger in the infotainment system was not functioning. The flight was 2 hours late due to crew rest requirements (not their fault). On arrival in Seattle, waited on the tarmac for 30 minutes with very few updates from the crew.

Flight was delayed and we were on the runway after landing for 30 mins

We were delayed so pilots can rest and had no WiFi the whole trip. First class seats are small compared to other planes

The experience was bad. Flight was delayed to handle maintenance (understandable) but still there was some dew forming and dropping as droplets on few seats. Internet at best was allowing some browsing but at a snail pace.

We were delayed 2 hours because of a broken seat. Other than that it was a very nice flight.

There needs to be better accommodations for waiting passengers. A a designated standing space that is separated and away from concourse traffic.

My seats are comfortable because I choose to fly in the exit rows and this time upgraded to first class with minimum sky miles. Otherwise, I would not be happy in regular seats or even middle comfort seats. Onboarding on the return flight from Nashville to Atlanta was hot and very uncomfortable for over 30 minutes due to extreme hot weather. However, Delta should provide some other air flow option as it was almost unbearable until 10 minutes after take-off. First class seats should be equipped with cup holders. Currently, the middle console is used and is flat and prone to spilling drinks.

I upgraded to first. Quick and easy boarding. Comfortable seat with power and a nice IPA.

Flight was delayed due to needing a replacement flight crew. Delta changed the aircraft type in Detroit. One hour delay. But once in the air, good flight

The flight was excellent. Their was no service as we boarded, the flight attendants spent about 30 minutes just taking and not really caring that the cabin was about 80 degrees and did not offered any beverage to first class passengers or any passenger. The flight from DEN to ONT is not long but not under an hour, we received one drink and bag of chips if you were lucky. I was in first class…. I did leave my hat on the plane and it only took less than five minutes for a United rep to locate and bring it to me.

Flight did not have wifi service. It was experiencing technical difficulties. Definitely and old plane that needs updating.

Very Poor. Significant delays getting to Chicago and then very poor communication on delays in Chicago to Cleveland. We could have rented a car and driven there faster than the delays ended up being.

The app logs you out right when you are boarding requiring all passwords and reservation number for the flight. Super annoying

The pre-order only approach for fresh food is really challenging

the seat has a problem. the back had a hole.

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.

Tired of being nickel and dimed for every little thing, especially carry-on luggage.

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.

Late start, late arrival and very uncomfortable seats. No legroom, no elbow room because the person next to me was fat. I had to press myself toward the aisle or be rubbing arms with them. As a result, I was bumped every time someone passed in the aisle. But I couldn't get away from the hip encroachment. Who wants to rub hips with an oversized stranger for over 2 hours? I'm not fat, just tall and larger-than-average frame so I need to leg room but it would be nice if other peoples' body parts weren't squeezing under and over the arm of the seating. Why should it cost me so much for simple comfort so United can get a little more profit?
