delta wifi wouldn’t work boarding was not in sequence flight crew spent most of their time on the phone with the lights off pretending no one wanted or needed anything

Friendly flight attendant Quick checking for baggage drop Quick TSA lines

Crew was absolutely fantastic and we’re so welcoming and friendly ❤️

We got stuck on the tarmac taxiing after landing early so we didn’t get off the plane until an hour later than we thought we would

It was okay. We were delayed for weather reasons, but the pilots and the flight control staff figured a way around the storm and were able to get us to Los Angeles safely. Not all the staff members were polite, but the entertainment on the flight was good.

So terrible. My flight was 4 hours delayed and we weren't notified til last second within an hour of boarding. WE had to sit on the plane for 4 hours. ridiculous.

Missed the Flight from Atlanta to Roanoke due to initial flight from Houston being 2hr. late. Now waiting 17hrs. till my first available flight.

Flight was 2 hr. delay, making me miss my connection to my final flight home to Roanoke. Now 12:38am in the morning and I just got the first available ticket at 5:30 pm tomorrow evening. Sleeping in the airport.

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.

It was a short, comfortable flight. It did leave an hour late due to the pilot having to be replaced (family emergency) but that didn’t inconvenience myself & my friend. The situation was explained, eventually.

Flight was delayed “due to earlier delays of that plane”, so we were nearly three hours late.

There was a piece of plastic baked into my buttermilk biscuit! I have a pictures. The flight attendants in first class were really apologetic, and tried to rectify the situation. I I am very appreciative that they were able to give me some packets of pretzels and gummy bears. I understand they don't personally handle the food until warming it up so I know it wasn't their fault. I don't know whether it was a newer aircraft, or different food packaging, but I was happy that when the food was being warmed up - it didn't smell like plastic. Jokes on me with finding plastic in my food.

The seats were uncomfortable, as if the cushions haven't been switched out in many years. I felt like I was on an old bus. The food was delicious. thank you. Onboard entertainment, very limited. Unless you like violent movies. Why in the world would you have such severely violent movies on a plane? if you don't want to see such things, you don't have a choice. Have you considered that when choosing entertainment? Good god. Why would you have the Godfather? Or black women being brutally beaten with a club? Why in the hell would you put that kind of material on a plane? As for Kayak: Why when I ordered Qantas, was the plane on United?

The head rest is too big and cannot be placed differently/removed. Causes one head to tilt forward and increase back pain

It was terribly delayed with zero support from united airlines. I reached at 1 am in the night. They did not provide any option to change the flights.

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.
