Bad. Flight was delayed due to maintenance issue with Delta. Seats were small, no service, bag got broken on initial flight. Cramped and hot. Sitting inside with no ac.

Flight attendent didn't let me sit in the empty window seat literally next to me. Doors had closed already so I moved over. She came over, asked for my ticket and made me switch back to the middle. The man on the aisle and I were right on top of each other. Seemed like a real power trip for no reason at all.

The flight was delayed and passengers were told that they will miss connections as flight may get 40-55 min late.

The flight from Atlanta to Tallahassee was delayed, not such a big deal because it arrived almost the same original time. Most of my complaint is that one of the boarding agents and one of the flight attendants seemed bothered and were not very friendly.

Be on time. No issues with weather etc. entirely on airline.

Good flight — left on time due to on time arrival of Pittsburgh flight

I think in the future I cannot fly anything less than Comfort plus. The seats vary depending on the plane. The people are extremely nice and funny. I try to only fly Delta if I can help it.

delayed take-off, then had to circle in air for awhile, wi-fi did not work, then the cabin got extremely hot multiple times and the luggage was at wrong carousel at LGA. In addition, plenty of overhead space so they checked bags too early. Horrible flight.

I missed the flight because the Minneapolis flight was 49 minutes LATE, and the Boise flight LEFT 24 minutes EARLY!

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

Phx - ORD was nice 737 with starlink and the ORD - grr was ancient bare bones airbus with not even a power port lol

It was easy to board, and the staff was friendly and helpful. What could have been better is that I shouldn't have to pay extra for a seat that doesn't recline.

Was on the plane sitting longer than the actual flight in air was, boarded at 5:45p and didn't take off until 6:50p flight was only about 30 minutes long. Just was poor experience will booking more with American Airlines.

Pretty much the exact same comments for this flight, there was crazy weather!

The guy in front of me was talking constantly, even when the pilot was making announcements. I found this very disrespectful to the pilot and to others.

The couple in front of me were constantly talking over the announcement from the captain and this was annoying me.

It was great. I really love the app. User friendly and very comprehensive when it comes to having information at my fingertips tips related my travel.

The bathroom was nasty. It has been so long since it had been cleaned that there was a urine cheese inside the toilet. The crew seemed miserable. The one black girl took no pride in her appearance. The experience felt trashy

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.
