Flight was delayed and then "they did not have time to load food". No snack or drink at all for 1.5 how flight. Somebody wasn't prepared.

No Internet, no backseat screen, no nothing. I bought a Delta ticket and ended up on American Airlines. How did that happen?

It is usually very pleasant. Good service for the price, international flights are even better

We never made it on this flight because we missed our connection due to o delayed flight from Jackson.

We had a terrible experience. The flight was delayed several hours, so we missed our connection. We were told to wait at the airport. At around 11:00 pm, the flight was cancelled. There were no available seats out of Jackson for the next two days. Fortunately, we had the foresight to rebook on United for the next day. However, we had to spend a long day at the airport and an overnight at a mediocre hotel. It was a miserable way to spend part of our vacation. We also sacrificed our $450 deposit on our California hotel because we could not get there.

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

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

Have not had a flight out or returning to Norfolk that has not required maintenance, and a gate delay. Properly staff the crew so maintenance can be performed without last minute emergencies on each flight and there is enough staff to have gates prepared for inbound flights. Staff to ensure the safety and on time service vs. profit.

Always pretty good as far as I see it. Staff was friendly and process was quick to get on and off.

Our flight was great with an unexpected upgrade. However, four days into our travel we are still without a piece of luggage. The bag tracker has not been accurate, the airline is not communicating with me or the luggage delivery service and no one is willing to take responsibility or guarantee any kind of support or reimbursement. Unfortunately, we do not have the option to easily shop to replace items as we are currently on a cruise. I have been very disappointed by United Airlines response.

There could have been better food options in economy on the long 7hr trip from IAH to AM.

The seats on this flight weren’t as comfortable as we had expected. Even leaned back these seats left us feeling crappy in our backs. Also we had to use our own tablets for movies, but nothing in the seats in front of us to hold the tablets up.

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.

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.
