It's fine but Newark to Nashville was too long

They delayed the flight 3 hours because it wasn't full they moved us to 5 different gates probably the worst airline ever not even spirit is this bad.

Poor communication, flight was delayed for preventable reasons. I missed my connection.

We had excellent customer service despite the chaos at George Bush airport in Houston!

The flight was delayed so we were dead tired, and after that the turbulence was horrible. I was very scared.

Was happy we finally got upgraded in 1st class. The seat getting old. The cushiness need some improvement.

Once we got in the air the pilot made up some of the time of the delay. So that was really nice.

We boarded but then sat there waiting on some missed connection people to get on so we sat for about 15 minutes for that. Then we sat again because the passenger manifest was wrong and they had to figure it out before we could leave. That took about another 20 minutes or so. The crew was working hard to figure it out so it’s not their fault. It ended up being a system glitch where someone was upgraded to first class while another person was also in the same seat and it just created a mess that took a little while to figure out. They literally went to every person on the plane asking their names to see who was sitting in the wrong seat. I also hate the entertainment that must be watched on your phone or tablet. Just give us setback screens. It’s so much better. Almost every Delta flight has this now and it is so nice to have them. The crew did a great job. I have no complaints from them. They were very hard working, even with the mishap and a disgruntled passenger.

For some strange reason I was put in zone 5 for boarding even though I had paid premium price for a premium seat right behind business class. This must have been a flaw because everyone else around me in the same zone (row) had been placed in zone 3.

I had requested wheelchair assistance prior to flight. The airport staff had no record of it. It was not provided at Cedar Rapids which was a small airport, so I managed on my own. At O'Hare airport the same thing happened. The staff told me they had no record of my request for a wheel chair. But they finally provided it after a delay when I insisted that I needed it.

The flight was delayed almost three hours. I understand delays happen from time to time, but this flight was delayed no less than 10 times. I wish the amount of time of the delay was more accurate, versus delaying in 10 or 20 minute increments many, many times.

Delayed by 5 hours and I had to wit in the airport for more than 6+ hours.

technology worked well and everything ran smoothly. The seats are quite cramped so please don't try to re-engineer the cabin to squeeze more bodies on board.

Flying in the United States with the major airlines has become so underwhelming. A 2-3hr flight in most other parts of the world with the major carriers of the area comes with newer, CLEANER aircraft and significantly better in flight service in terms of both staff attitude and a actual meal service.

Delays experienced in boarding/take off due to incoming plane delayed. However, the boarding time/depart time in the app was significantly delayed in providing these updates. Usually not updated until an hour after we should have already boarded. Poorly managed.

The plane was experiencing problems with the HVAC system, it was very cold in the front of the plane and very hot in the back.

Plane was delayed for 6 hours, at first by weather, which is understandable, but was further delayed with NO given reason for 2 1/2 hours more. We had no clue when we were going to depart actually until they opened the ramp. VERY POOR to ZERO COMMUNICATION!!!

At least it was a short flight. Greyhound with wings.

Delayed, missed connecting flight, ground crew double charged for international charges, were super rude and told me to just”deal with it” when I complained. Horrible airline, very frustrating.

Our flight got changed and/or delayed 8 times before we boarded.
