Both legs on the way were smaller planes, each had a mechanical issue causing a delay

Delta exceeded my expectations! I am beyond satisfied. Thank you!

Flight was on time! That's the most important thing for me.

Delayed flight. Dirty seats, dirty seat belts with food stuck on it from previous passengers maybe. No one cleaned the seats or flight.

The flight was delayed and knowing I was going to miss my connection, nothing was done proactively to try and get me rebooked. It was an act of congress to do so. This is not on the crew, but on the experience itself

No headphones, forced to sit in another seat that I did not book, had to check my carry on when I boarded the plane I saw backpacks and other non carry on items stuffed in the carry on holder! Horrible experience Wi-Fi did not work either

Sat in the tarmac at O’Hare for 65 minutes. This is a regular occurrence for delta at O’Hare

Delta is getting worst by the minute. Where this was at one point my only go to airline, it has become like a budget airline

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.

Great Brasilia aircraft - not a Boeing 757 like the next part of the flight. Flight from MCI to IAD was great, on-time, comfortable, did I mention that? The flight from IAD to EDI was painful. One of the reasons I won't fly United again? Boeing 757, with a seat pitch and material that was horrendous. Worst aircraft ever, made worse by United sardine-can tight seating. Oh, and the connection window, 45 minutes, really? At IAD, in different concourses? What idiot came up with that flight scenario? Happily, (for me and my travel insurance people) the flight was late (reminiscent of American Airlines). The crew was professional and courteous.

Crew was great. Seats are cramped and uncomfortable and I’m a small person.

Awful. Delay after delay. And then again on the tarmac.

WiFi was slow as compared to trip down. Maybe because it was a night flight and more people were using it?

Excellent except for the 2 screaming kids who wouldn’t stop crying and screaming for the entire flight but what are you going to do? The flight was early- good experience

Kept changing the takeoff time and the moved it up so arrived when boarding had already started. Then sat waiting to taxi in for a long time

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.
